3d printing in classrooms with FreeDee 3D Academy and Makerbot

3D printing in european classrooms? If you think that techies are the only ones using this technology, think again. We here at FreeDee 3D Academy don’t have to look far from our office in Budapest downtown to see how middle school students are using 3D printers. And why not? 3D printers are a natural for STEM education, an initiative that prepares students to excel in science, technology, engineering and math. The future of STEM (science, technology, engineering, mathematics) education may depend far less on traditional teacher-student hierarchies than on supportive communities of people who have diverse, complementary knowledge and enthusiasms. Knowing how to look up information and to tap into others’ specialties could become the real keys to STEM success. And the hands-on, do-it-yourself culture of the Maker Movement, along with the Makerbot 3D printers supplied by FreeDee Printing Solutions and other tools that animate it, might play a singularly important role in reinventing libraries and schools to work this way.

But this time, a catholic middle school next to the Ukrainian border in Kisvarda has managed to set up the very first FreeDee reference 3D lab fitted with 4 Makerbot Replicator desktop 3d printers and a 3D Systems Sense handheld 3D scanner to support the education of teenagers in the STEAM education including arts and social sciences. To help students and others get past their fear or dislike for science, the director of the school and the teachers strongly favored a connected learning approach. Connected learning encourages people to identify the relevance of STEM topics to things about which they are already personally passionate. In that context, STEM can seem more meaningful and directly valuable, so individuals will be more motivated to learn the associated science.

The St. Laszlo Catholic Middle School in Kisvárda, Hungary provides education for children from the primary and middle school. The school has purchased a set of professional desktop 3D printers and a 3D scanner through a couple of grants a couple of weeks ago, and the innovative technology has already made its presence known. Sixth and seventh grade students in robotics classes have recently designed and 3d printed custom designed mechatronic parts to improve their robots built from Lego Mindstorm kits.

The students and their creative teachers have also created a number of other objects with the 3d printers, such as: replicas of ancient temples, nuts and bolts, geometric solids, stencils, dragonflies, cells, mathematic demonstration models, human and reptile bones, custom parts for a laser scanner, and of course some rings and headbands.

Last year in December, the management of the school collaborated with FreeDee 3D Academy in Budapest to set up 3d professional Makerbot Replicator 3D printers and give one extra Makerbot Replicator 2 to Szt Laszlo Middle School in Kisvárda, Eastern-Hungary. They’ve already made great strides in learning how to create objects with the printer. Laszlo Jura, teacher of IT and Robotics, says the only challenge is designing with 3d printing in mind. He says the trick to an easy print is making sure the object is oriented optimally to avoid unnecessary supports and to give the most stable base for the 3d printing process.

Students in programming and technology classes and the school’s robotics club started off 3d printing trinkets, also made of ABS and PLA, in the school’s STEM lab, which is actually a Makerbot Starter Lab including a 5th Generation Makerbot Replicator 3D printer, a Makerbot Replicator Z18 large format 3D printer, a Makerbot Replicator 2X experimental dual-extrusion ABS printer and the most popular desktop PLA printer, the Makerbot Replicator 2. After learning the mechanics of the 3D printer, they’re now putting their printers to use for a good cause. In the next couple of weeks, they will meet with representatives of the local organization of E-nabling the Future, called E-nable Budapest, an organization with a mission to partner with schools to use 3D printers to print hands and arms for children born without any. It is some kind of charity movement, because a lot of patients in Hungary cannot afford to buy medical prosthetics while their infants are growing.

As featured on the local news, they’ve been 3d printing and building prosthetic arms and hands in the school’s STEM lab. Soon, the students will use the 3d printers to print a prosthetic arm and hand for their principal, who was born without a left hand. Kerezsi director says making an arm-hand combination will take some time and planning and will involve a good bit of measuring, printing, fitting, re-building and re-fitting. But he’s sure the students are up for the challenge.

Some of the students say that may pursue engineering later in life, but for now they enjoy the active learning and using the 3D printer for a good cause. This approach to STEM built around personal enthusiasms dovetails with another trend, the rising interest in the Maker Movement—and in equipping libraries to become community centers for Maker activity. The Maker Movement is an extension of traditional DIY hobby craft culture that embraces digital technologies such as 3D printing and robotics.

Last friday, on the 29th January, the middle school has made an open day for its partner institutes and regional companies of Eastern-Hungary to showcase their brand new lab with the 3D printers and 3D scanner. They have fought about their experiences with the additive technology, how they already have profited from the affordable desktop 3d printers using them to create educational demonstration models. Since the installation of the equipment, they already have printed dozens of colorful plastic models for making the education more interactive and allow children to experience the power of the brand new digital fabrication methods.

After the opening ceremony, the teachers and gifted pupils have shown the audience in 4 different places how they have implemented 3d printing in their educational practice. In the first classroom, participants have thought how a physical object can be made out of scratch: they use free and open-source CAD modeling programs like FreeCAD or Leopoly to create 3 dimensional meshes. After that, they check and clean-up the model to prepare it for 3d printing on Makerbot Desktop 3D printers. With the Makerbot Desktop software, they place the virtual model on the printed and fine tune the printing process to be able to get the best results out of the machines. After an object is printed, they also give it a perfect finish with sanding and painting them. The results? As you can see, they have managed to produce a huge amount of educational models, for some coins. This way, they just saved a lot of money while the innovation drives a lot of attention from the region to the institute.

According to recent information reported by the BBC, experts say we are headed for a boom in 3D printing, citing estimates that the market will top $16.2 billion in 2019. While you may already consider it to be booming just by the amount of press the technology is receiving, the idea is that those graduating with the skillsets currently are going to be melding with the initial need within industry. The timing will come together perfectly with large companies finally being convinced to turn to 3D printing. And as many guidance and career counselors in schools will be explaining to masses of graduates, companies are looking for: industrial engineers, mechanical engineers, software developers, commercial and industrial designers and marketing managers.

The Technology Outlook for STEM+ Education 2013-2018 recognizes learning analytics, mobile learning, online learning, and virtual and remote laboratories as technologies expected to enter mainstream use in the near-term horizon of one year or less. 3D printing, games and gamification, immersive learning environments, and wearable technology are seen in the mid-term horizon of two to three years. Finally, flexible displays, the Internet of Things, machine learning, and virtual assistants emerged in the far-term horizon of four to five years.

“3D printing allows for more authentic exploration of objects that may not be readily available to education institutions, including animal anatomies and toxic materials. The exploration of 3D printing, from design to production, as well as demonstrations and participatory access, can open up new possibilities for learning activities.” writes the report. “Typically, students are not allowed to handle fragile objects like fossils and artifacts; 3D printing shows promise as a rapid prototyping and production tool, providing users with the ability to touch, hold, and even take home an accurate model.”

We’ve seen 3D printers in action in STEM education, and we also use one here at FreeDee 3D Academy in our design process. What fields have you seen 3D printers at work? Let us know.

Budapest 3D Printing Days 2015 is coming next week!

On the 14th May 2015 the 3rd edition of Budapest 3D Printing Days is going to open its doors for a three-day extravaganza on 3d printing, additive manufacturing and associated technologies. Great speakers will build the core of Budapest 3D Printing Days’ outstanding line-up of conference sessions and interesting 3d printing or 3d scanning related workshops. Whether that business involves desktop consumer 3d printing, manufacturing or even hobbyist tinkering technology (maker culture), this years event in the heart of the Hungarian capitol will be the place to do the business.

The aim of the exhibition and thematic keynote sessions is to provide inspiration and education on all things designing and making – be that in an international aerospace and defense contractor or for homemade prosthetics for children and young adults. The 2015 line-up consisted of the leading lights from the companies that both provide and use the tools we’ve been covering for the last couple of years. The organizers have something different for this this year, but more of that later. The space for the show like the main exhibition area at Akvárium with the 3 halls, the conference hall at Design Terminal and the workshop space in Design Terminal’s pavilion were larger than for 2013 or 2014.

When I first visited the Budapest 3D Printing Days in 2013 there was a small and somewhat dispersed representation for the 3d printing industry, although as an exhibitor I absolutely felt happy and found some good friends and businesses during the 5 days of the show. The exhibition and workshops with working 3d printers have been really popular, the organizers decided to go bigger with the next years event. The Budapest 3D Printing Days 2014 has been the most prominent Central-European 3d printing event with a lot of exhibitor from the V4 Countries like Poland or the Czech Republic. For 2015, Design Terminal made a huge impact by launching the biggest and newest range of the regional 3d printing market, in this way the event wants to be even bigger: the region has its own leading cores and the organizers want to connect all the regional businesses around the local 3d printing industry. I really like the concept of becoming the place for regional desktop manufacturers to launch their awesome machines, for example the professional grade DLP 3d printer of Do3D, the super-affordable spider-like deltabot of Krak3n or the affordable industrial SLS 3d printer of a small company. Some ’traditional’-style desktop 3d printers will take place as well, like the CraftUnique 3d printer from Craftbot, which is already in production thanks to its successful indiegogo campaign.

The first day starts with the official opening ceremony, where all the companies will represent their products for the press and audience for a few hours. The conferences will take place on 15th May, the workshops will run continuously during the 3 days of the Hungarian 3d print show. Even you are a hobbyist or a professional, the most interesting day for you might be the conference day: the morning will kick off with some keynote speakers representing the longest-established companies in the industry like Arduino (Davide Gomba) or Makerbot (Alexander Hafner). Almost twenty speakers will take to the stage over the day, spanning the veterans and newcomers to share their vision for the technologies and application for the next couple of years. I hope I won’t miss the interesting lecture of Cristina Nan from Architecture Hafencity, and of course we really can suggest our dear friend David Pap from FabLab Budapest with their interesting workshops about generating custom g-codes for desktop 3d printers using grasshopper or 3d scanning techniques with photogrammetry or laser-scanning. How we make things today and how we made things twenty years ago has changed drastically thanks to the increased accessibility and power of computing solutions – will the same be true for the 3d printing technologies on the Budapest 3D Printing Days showfloor?

GigamaX3D and parametric | art have been central to Design Terminal’s Budapest 3D Printing Days for some years now, retaining a central position and substantial double-stand since the 2 companies work together from the beginning. They will be having their main, twin-desk booth which will be in a central place of the main hall, where they will be demonstrating the consumer and professional desktop 3d printers and materials and the production applications of affordable and/or open-source 3d printing technologies – including end user parts as generative jewelry, lampshades and sculptures by parametric | art. If you are curious what you could expect from the two companies for 2015’s event, you’re at the right place because there will be 2 workshops for generative 3d printed jewelry design and DIY 3d printing, which are open for the public during the Hungarian 3d print show.

GigamaX3D is going to be showing some brand new products and a couple of evolutions and improvements to already existing products. On the FDM desktop 3d printer side, they will showcase the Leapfrog professional 3d printer systems, the Creatr and the Xeed, and they also will run a fully open-source assembled K8400 Vertex 3d printer KIT, which also will be explained during the 3d print workshop on saturday. Some of he 3d printers at the booth will be 3d printing prosthetic hands for young people for the e-NABLE project with Joe Cross, who also will be a speaker and exhibitor at the Budapest 3D Printing Days. I am glad to spread the word about e-NABLE and how we can help in this area, because until recently, they did not have any e-NABLE volunteers working in Hungary.  Thanks to this event, they will be able to recruit new volunteers and help many children. The idea of desktop 3d printing being used at the point of need (or indeed by the person with need) to create healthcare solutions os something that will touched upon Joe Cross in his presentation. Honestly, I’ve never seen a project like e-NABLE developing such a great movement, so guys, if you have a 3d printer at home, don’t hesitate and support them with some prints you can afford.

I hope I’ve made some attraction to the event and if you’re around you will visit us at the Budapest 3D Printing Days, the event also has a facebook page and a microsite where you can buy tickets for the workshops and register as a visitor. The exhibition and the conferences are free to attend for everyone, so don’t miss the opportunity to get the freshest news from the 3d printing industry! Actually, one of the headliners of the huge 3d printing new portal (3dprintingindustry.com) will be a keynote speaker as well! See you there next week;)

The best 3d printer filaments for the best price, is it a fairy tale?

With the exponential growth of the desktop 3d printing scene, even more and more hobbyists and makers are looking for the cheapest plastic filaments for their self-built or out-of-the-box 3d printer. If you google ‘em, you can easily realize that you can get the best prices from the far east, but you should know you mostly get what you pay for when it is about the 3d printer filament prices and the material quality.

In this entry, I just want to make clear a few things about choosing the optimal 3d printer filament for your needs, depending on what you want to use your 3d printer for. There aren’t any 3d printer filaments for universal use, the maker itself has to decide in every 3d print job which kind of extrudable plastic is the best for the actual needs.

If there were an award for the most innovative desktop machine of the 21st century, it might well go to the desktop 3d printer. These machines, which turn digital designs and virtual 3d models into real physical objects made out of plastic or other materials like 3d printed wood or sandstone, are getting better, faster, simpler and cheaper at such a dizzying pace that it’s not hard to imagine a future in which they’re as pervasive as personal computers or mobile phones. Just think about the beginning of the internet. There are some common points and milestones in their history. And already, you can buy a basic desktop 3d printer for about €450.

building open-source 3d printers

But it isn’t the best decision, however, to hung up on the incredible low prices of the 3d printers themselves. Just think about the most common and conventional 2d inkjet printers which need those expensive ink cartridges every month, affordable desktop 3d printers can work with open-source 3d printing materials with the specified diameter and 3d printing guidelines, other work with cartridges using a built-in chip which makes the system closed. Of course, 3d printer filament cartridges are more expensive than the normal PLA, ABS, HIPS or wooden 3d printer materials, although the material is made in the far east in every single case. Although the plastic pellets of the raw 3d printing material is quite cheap, the spools of plastic filament which a 3d printer layers into an object have a huge impact on the long-term economics of 3d printing.

If you don’t want to pay a huge amount of money for expensive, brand-specific 3d printer filaments, you have a lot of opportunities: if you’re a hacker kind of guy, you can produce your own filaments for your 3d printer by purchasing or building a 3d printer filament extruder like the Strooder, Filastruder projects appeared on Kickstarter a couple of months ago. If you don’t want to turn your bedroom into a plastic factory, you can search for the cheapest 3d printer filament suppliers on the web to get the best offer. It can build up some trust if you see a lot of people using the type of 3d printing material you want, it is always good to see the results of other 3d printers using the same plastic material from the same supplier.

We’ve complained about the high price of 3D printing filament, and cheered at the machines that makes filament for the 3d printer out of plastic pellets. Still, the costs of the material for our 3D printers is getting higher and higher, making every hacker and maker searching for the cheapest 3d printer filaments on the internet. Trying to find the best 3d printing filament supplier is always a work in progress. Canvassing suppliers on every continent for 1.75 and 3mm ABS, PLA, HIPS, PVA, Nylon, Conductive, Flexible or wooden 3d printing material for every possible color while accounting for different amounts and spools of filament and shipping is a whole lot of work. Therefore, I’m going to describe it from the european point of view, first starting with how much it will cost somebody like me to get a kilogram of usual 3d printer filament shipped to my door. And this way I only think about local 3d printer suppliers.

3d printed wood

If you do some research, you might realize that the cheapest spools are from China or the Far East, which means you have to pay the taxes and high shipping costs for your 3d printer filament spools. If you order it with airmail, it is incredible expensive, if you choose the normal transport, it can take months until the package arrives. A fact is a fact: you’d better choose a 3d printer supplier in your neighborhood because you can check the quality and have some warranty for the quality of the product. 3D printing materials aren’t easy to produce, it can be made wrong both overseas and here in Europe. GigamaX3D wants to bring 3D printing accessible to everybody, so that everybody with an idea for a product can turn it into reality. They think that open-source 3d printers like the Velleman K8200 3d printer KIT or the Flashforge Creator desktop 3d printer and cheap 3d printer filaments could help.

In the GigamaX3D 3D print webshop you can find the cheapest 3d printer filaments with a high quality. They also offer premium 3d printing materials for special applications with higher accuracy and strength, but you also can order ABS, PLA, HIPS, PVA, Nylon, Wood, Conductive or Flexible 3d printer filament spools at an incredible low price starting from € 12.70 / 1 kg. The premium filaments are made in the EU by Fillamentum, which is a czech plastic filament manufacturer with the highest quality materials and most beautiful colors. You also can find filaments from the far east, the cheapest spools are made in China by Esun and are widely used with success around the world since it’s one of the most popular 3d printing filaments.

All the chinese and european 3d printer filaments distributed and used by Gigamax 3D printing technology are extruded with inline laser diameter control for guaranteed quality, and have a tolerance in the cross section dimensions better than +/-0.10mm. They just have started a promotion offer, which means, if you place an order above 10 spools (except the discount white PLA) you can get FREE SHIPPING to the EU using the coupon code 10PLA at the checkout! That means, you can get many colors of PLA, ABS, and HIPS 3D PRINTER FILAMENTS for € 16,50 / 1 kg spool with free shipping! In my own opinion, it’s the the cheapest 3d printer filament available in the EU I ever met. But price is one thing, let’s have a look at the quality of the 3d printer filament. PLA and ABS plastics are the most common 3d printing materials, but the devil hide in the detail and it all goes about the diameter accuracy. I can’t test if the given tolerances were true or not but I know a lot of people who are using Gigamax 3D printer filaments with amazing results on different types of 3d printers with FDM technology. An architect/designer and 3d printing enthusiast, who runs parametric | art generative 3d print studio in Hungary works always with the cheapest Esun filaments purchased from GigamaX3D, a girl who makes unique jewelry with a 3d printer mentioned GigamaX as a filament supplier on her blog as well. The universities and high schools use 3d printers and filaments for different use, the technical and material support is mostly provided by the Hungarian 3d printing company.

Affordable 3d printing pen from Velleman

As I discovered when I could give a try to the 3Doodler handheld 3d printer back in March, 3d sketching in the air can totally be great fun. Let’s make it clear, you won’t create any flying machines or 3d printed musical instruments but it is possible to serve up something more elaborate than a squiggle ball with a little practice. The only problem with the original 3d printing pen construction is that it’s way too heavy to create precise drawings and is uncomfortable to use after a while.


3d pen for sketching in 3D

3d printer pen by Velleman

Just like in most cases of the 3d printing industry, after the successful kickstarter project of the doodler, a lot of chinese clones appeared on the market. The only problem with chinese suppliers is that you never can trust any quality values and replacing parts or getting support might be an impossible mission as well. You’d better get your 3d printing pen at a local supplier who cares about warranty – and if not, it will have consequences – and this way you can feel safe with your brand new 3d printing device.

But parents, please take care if you want to buy a 3d printing pen for Christmas, the tip of the machine can be really hot which can easily burn one’s hands! So please make sure that you child won’t touch the nozzle while sing the 3d printing pen, and you better do not leave it alone with it.

3d printing pen

3d pen by Velleman which works like a 3d printer

In this blog post I would like to show you a brand new 3d printing pen, this one is from the Belgian company called Velleman. Their amazingly popular K8200 DIY 3D printer KIT made them recognized in the worldwide maker community, although they’ve been producing DIY electronic kits like arduino shield and other professional electronic solutions for decades now. The new 3d printing pen has got some benefits and useful features like the 1.75 mm filament mechanism, which allows you to use any 3d printer filament from the cheapest PLA 3d printing filament rolls to the premium quality filament spools which allows you to 3d printsketch with wood or sandstone instead of being bound to expensive filament sticks.


There is a real 3d printer extrusion mechanism trapped inside the cigar shaped device. On the whole, many things has changed to the 3d printing pen’s shell design since the designers of the 3d doodler created their successful kickstarter project. The oblong device is covered in a white and blue hard plastic casing. It’s lightweight and easy to hold between your thumb, index and middle finger, just like a thicker ink pen.


3d pen for drawing in 3d

3d printer pen by Velleman

The Velleman 3D Printer Pen has debuted at the Maker Faire in New York. The 1.75 mm 3d printer filament extrusion system allows you to use all the common FDM 3d printing materials like ABS, PLA, HIPS, PVA, Timberfill (wood), Luminuous, Flexible, Conductive and so on… For example, playing with the conductive filament and sketching circuits in 3d or ON 3d surfaces can be an interesting stuff, I’d like to give it a go on some organic 3d printed designs. But let’stalk about the Velleman 3d printing pen, which is an absolutely great xmas gift, but for you, not for your toddler. Just check out the specs and prices, you can forget about the filament price because you can order 1 kg spools for about 20€ which last for a year or more…

  • dimensions: 7.3 x 1.7 x 1.2 inches (187 x 43 x 31 mm)

And how does the Velleman 3d printing pen work?

Literally, it is a small 3d printer extrusion mechanism integrated in a pen-shaped case, which melts and extrudes 1.75 mm thermoplastic filament sticks which can be deposited anywhere from ground instead of the layer-by-layer modeling technology of the desktop 3d printers. This gives you the possibility to build an huge variety of geometries and structures with ease! Most people will instantly be able to trace objects on paper, and after only a few hours of practice you will be able to make far more intricate objects. Just like a glue gun, but this 3d printing device doesn’t extrude thick plastic stick. This 3d printing pen extrudes heated 1.75 mm filament (PLA or ABS, which filament cools down once it’s out of the nozzle. This allows you to build 3D structures and shapes.

Why is it better, than the Doodler?

Because it is lighter, easier to use: you only have to plug in your 3d printing pen and wait until it heats the extruder. Once the wanted the temperature achieved, you can set up the speed of extrusion and start creating some magic! Especially for the holidays, just think about some awesome, lightweight truss-like christmas ornaments with your 3d pen! You can use any kind of 1.75 mm 3d printer filament in any colors, GigamaX3D also offer special 3d printing pen packages including some rolls of premium 3d printer filament or conductive 3d printing plastics.


Who is the Velleman 3d printing pen for?

3d pen by Velleman

3d pen kit with 3 spools of filament – for €71

For anyone who would like to draw in the air! It is a toy for adults, not for your children! It is not allowed at the age of 12 but your older teenager children would surely like it! I also have purchased my own copy because I though it will be a nice part and a great additional tool of my 3d printer collection. I already have a Flashforge Creator X Dual extruder 3d printer, which is a great copy of the Makerbot Replicator 2, which I also own. The Rep2 has been modded, it has an open-source controller and runs sailfish now, because I don’t want to be bound to MB’s presets or adjust the setting in text editor while modifying the profile files. I also have a Velleman K8200 open-source 3d printer kit, but I don’t use it for 3d printing: I’ve turned it with some open-source upgrade parts and a Proxon drilling machine into a simple CNC mill which can engrave or mill PCBs or soft materials like Styrofoam. The next thing I want to give a try to is the chocolate extruder, as you can see it on this video, it can print a chocolate mug on your toast for a delicious breakfast at the holidays! And if you want to complete your 3d printer setup, you also should have a 3d scanner which allows you to capture your environment in 3d and prepare it for 3d printing! You also can draw some hair or make-up on a 3d printed sculpture like these 3d printed Halloween monsters.

If you already are a 3d printer owner and maker, you can fix and repair your failed prints with your 3d printing pen. Just fill the holes, glue broken parts or pimp some old and failed plastic parts and turn them into some piece of art! In forthcoming world of new devices like 3d scanner and 3d printers, the Velleman 3d printing pen offers something creative, special and unique, allowing you to create strange new works of art – and it is truly affordable and a great xmas gift for about 70 Euros, including some spools of 3d printer filament. The 3d printing pen may look like a tech gift for 3d printing enthusiasts but thanks to its easy-to-use mechanism it can be a creative tool for everybody who like making things on their own! You also can print some graphic pattern on your 2d printer and then draw it with you 3d printing pen using heat-resistant translucent kapton tape on it! Have you ever tried a 3d printing pen?

The most prominent 3d printing event in Eastern Europe is coming!

Additive manufacturing and 3d printing is an amazing technology with unrivaled capabilities. There is no need to provide anything less than the unvarnished truth. When additive manufacturing’s advantages are wanted and needed, the facts will not dissuade potential users. Yes, it may lead to specific technologies being eliminated from consideration, but that is for the best for everyone involved. If you are interested in 3D printing, come and join the Budapest 3D Printing Days 2014 to get some really close experiences about this fascinating technology.


Whether you just want to see a real 3D printer in action for the first time or share your success with an advanced application, the best way to experience this technology is in person. In the company of engineers, designers and 3D printing experts around the globe, you’ll find out how to make the most of additive manufacturing in your scene.


When starting with this article, I was wondering about the 3D printing bubble – the theory surrounding the exponential rise in popularity the technology has seen in recent years, in particular the saturation of the desktop 3d printer market – is becoming a victim of its own success. Because the realm of 3d printing is no longer consigned to the underground-hacker-maker RepRap 3D printer community and/or industrial powers of this world, and because everybody from Barack Obama, Jay Leno to that chap from Made In Chelsea seem to have one, is 3d printing loosing it’s ‘coolness’?

I remember that it wasn’t a long time ago that 3D printing was a little-known term of the high-tech industry. And now, today it is a household name and an accepted technology entering its next major development phase. Right now, we can see 3D printing and all the hybrid additive manufacturing solutions for production taking off and we believe will fundamentally change the world of manufacturing.

In the last couple of years, the global media has given 3d printers a fair amount of attention and the industry now has great expectations placed on it. Perhaps the greatest asset of 3D printing is that it is an enabler . for both corporations and individuals. In fact, 3D printers is being used in three types of manufacturing and fabrication processes: personal manufacturing, augmented manufacturing and alternative manufacturing.

The oversimplification of 3D printing in the media and in conversations does the job of grabbing attention and drawing focus to the highlights of this fabrication process’ capabilities. That big picture has involved more and more people and attracted more interest in 3D printing than ever before. But of course, for an average customer, the details are missing. Without them, you can make poor decisions and you may conclude that 3D printing isn’t quite right for you. But you might know that the devils is in the details, and as the idiom indicates, getting to them may be a challenge for you.

The jewelry industry already understood the importance of harnessing the power of 3D technologies and additive manufacturing for the benefit of the industry in general – and training the next generation of jewelry designers. Parametric design processes like computational algorithms and data based design are the new tools for young designers, and the digital design combined with fully digital fabrication allows them to create some really amazing pieces using a CAD software or only coding.

There are some breathtaking projects around, you have to check out Nervous Systems Kinematics Home app to create custom generative jewellery pieces which can be downloaded and 3d printed on your personal 3d printer at home. Of course, you’ll need a desktop 3D printer with a resolution of 50-100 micron to be able to make high quality prints, nobody wants to wear something barbed. Post processing might be necessary, ABS prints can be smoothed in acetone vapour to get a shiny finish (fine details and contours often disappear during the smoothing process).

When it comes to getting the best out of 3D software and a desktop 3D printer, we can keep in mind that this technology is still a complementary tool, it supports and enhances traditional techniques (like lost-wax casting for example), not replacing them.  It’s a technology that gives the jeweler a new set of tools (both for design and fabrication), but it’s not a replacement for traditional skills. When we are talking to a designer and they want to design a conventional wedding ring, they would not need to take advantage of the things 3D printing offers because on many cases, traditional manufacturing techniques are better placed to do so. According to this, we can say that a 3D printer won’t put a traditional jeweler out of his job. The whole new process of 3D printing only saves designers from having to model the initial part of the design from scratch.

It is a really nice idea for students of for those trying out the technology, to push the technical boundaries of jewelry design and manufacturing with new digital tools as a pattern language. Fashion design, industrial design, architecture and jewelry already adopted the parametric design language which allows the designer to generate a huge amount of variations and iterations for a defined situation depending on fitness values and genetic algorithms. There are some open-source tools for generative design, which makes this game much more fun!

A dear friend of mine has designed the generative 3d printed jewelry pieces shown in the pictures I’ve inserted, I think they all look really unique, and they all came out from an affordable desktop FDM 3D printer. Most of them are 3D printed on a Leapfrog Creatr Dual extrusion 3D printer, some of them have been printed on a RepRap Huxley or the Velleman K8200 3D printer. In some cases, he has made some test prints on a Makerbot Replicator2 as well. I bet you’ll like all the stuff of the parametric | art 3d printed generative jewelry collection, for some design, there are already uploaded design files (.stl) on Thingiverse, so you only have to download and scale it, and then 3D print it!

The illustrated 3d printed jewelry pieces are great examples for the quality which can be reached with a well-calibrated 3D printer and using premium quality 3D printer filaments. For the chiseled details and overhangs, you’d better print these kind of objects with high resolution (100 micron or finer) and use water-soluble PVA 3D print support material to avoid the trouble while removing supports manually.

If you want to design and 3d print your own generative 3d printed jewelry (for example like the voronoi bracelets on the picture above), you don’t need to buy any expensive stuff. You don’t need a professional CAD software which are really expensive, there are plenty of open-source and free tools which you can use as well. Just like I described in a former blog post about 3d modeling for 3d printing, you can use Meshlab, Grasshopper for Rhino and Meshmixer for the modeling work and Netfabb or similar software for optimizing and repairing you meshes before generating the g-code. If you want to learn this stuff, there are some really nice workshops offered by Gigamax 3D printing technology.

Which filament is the best for your desktop 3d printer?

From engineers, plane- and car manufacturers to architects, artists and other product designers, they all use 3D printing to test if their designs come out the way they were intended. Thanks to the winde range of open-source and affordable desktop 3D printers and cheap 3D printing materials, schools, students, small offices, makers, enterpreneurs and professional designers are now able to set up a studio full of 3D printers to have their students or consumers (workshop participants) experiment on their own. In this article I’m going to discuss the most important facts when choosing the filament for your 3d print. There is a huge amount of companies and webshops offering PLA and ABS filaments for 3D printing, but if you aren’t carefully enough, you can get some really serious issues with bad filaments.


Most desktop 3D printers use the fused deposition modeling (FDM) technology, which means, that they all work with plastic filaments with 3 mm or 1.75 mm diameter. The hot end of the 3D printer heats the filament which melts before being extruded from the nozzle. Most 3D printing plastics have a melting point from 180 to 240 Celsius. After 3000 hrs of 3D printing on my Makerbot Rep2 and several types of RepRap 3D printers, my tip would be: if you want to start 3D  printing, you have frustrations enough (mechanical and electrical issues), spend a few extra bucks to eliminate possible filament issues. I’ve tried several suppliers of 3D printing filaments last year, from the cheapest ones to the premium quality spools as well. The moral of my story is:  you get what you pay for, buy materials from a trusted and verified supplier where you know who makes it, and watch out what you put in your 3D printer. 3D printing is already hard enough without nozzle blockages to deal with.


Unfortunately, the nozzles of the usual desktop 3D printer setups aren’t self-cleaning, so you can have some dust or particles while feeding the filament into your extruder head. Accumulated dust/dirt on the filament, or even actual debris inside the filament, can partially or fully block the narrower output end of your nozzle. High quality filaments come vacuum-packed and sealed for your security, but I’d suggest to check it before you put anything into your 3D printer. I’ve found some really cheap stuff on ebay as well, but the pain of clogged nozzles and wasted failed 3D prints its not worth it.


Some 3D printer extruder constructions might be sensitive to the diameter of the filament, it may be have problems if your roll of filament varies widely in diameter.  I’ve had some bad experiences with the Formfutura supplier, although I’ve ordered several spools from them. With the FlexPLA and the Laywood, I haven’t got any problem, but with their normal PLA spools I have discovered some irregular values after measuring the diameter. I mean, the cross section of the filament should be round with a diameter of 1.75 mm, but mine looked like an ellipse with 2.05 mm along the longer axis. Unfortunately, the hot tube of the extruder of the Replicator 2 has only a 2 mm hole in it, so the filament just got stuck int he hot tube while feeding.


I had to take my 3D printer apart, remove the clogged filament and clean all the parts before re-assembling. Sometimes, the diameter variation could be gradual; in this case, you might have great print jobs for a long time, and then unexpected as the filament gradually gets narrower, you have an extrusion issue.  Or, as the filament gets wider, you start to have an over-extrusion problem. I’ve already read some reports about knots ont he spools, int hat case, those plastic spools weren’t originally manufactured for 3D printing, maybe they are common plastic welding rods sold as 3D printing material. If you have experienced knots or stuff like that, you’d better switch to higher quality filament (like the filament that Gigamax3D sell) that is made specifically for 3D printing. I’ve found that supplier a couple of months ago, and I’ve been really glad because they are from nice quality for an affordable price. I’ve tested them before buying, because they have a store in my country so I could measure the diamter of the sealed spools. They have allowed me to test every spool I wanted, and their filament passed the tests with my micrometer. It was the first time I bought some HIPS spools, and they worked fine as well.


Gigamax-supplied filaments have been tested to conform with all the common desktop 3D printers’ specifications and work best for most applications.I you already have some experiences with desktop 3D printers like RepRap machines, Makerbots, Leapfrog 3D printer or any other FDM 3D printer, you might have discovered as some filaments won’t work fine or can cause serious damage to the extruder head and machine. The quality of your 3D prints depends ont he quality of your 3D printing material as well. That’s why it is important to use high quality filaments for 3D printing. Gigamax offers an array of plastic filament colors. If you visit the Gigamax 3D print webshop  you can see the full range of colors and special materials like glow-in-the-dark PLA or HIPS filaments in bright colors. All Gigamax 3D printing filaments come in a vacuum-packed foil bag with a desiccant pack to keep the ABS, PLA and HIPS spools dry during storage.


They also sell PVA material, which can be really useful if you have a dual extrusion 3D printer like Leapfrog Creatr or a multimaterial RepRap machine like the Tricolor Mendel. 3D printing with FDM technology is really popular because of the simpliness of the process. There is no finishing necessary when 3D printing with extruded PLA, ABS or HIPS filaments. After the FDM extrusion process, the plastic solidifies right away. No chemical reactions, resins, etc. and no further post-processing and/or finishing needed. In case you use a 3D printer with multiple extruder heads with the water-soluble plastic PVA plastic as a support material, you have to dissolve the PVA in water after your print is finished. PVA is an amazing material, unfortunately it only can be used with at least 2 extruders and costs a little bit more than usual 3D printing plastics.


Since I switched to Gigamax3D filaments I haven’t got any issues with filament diameter and clogged nozzles, unless I unloaded the HIPS filament and loaded some Laywood and Laybrick material. I think that some particles may have stayed in the brass nozzle and that’s why it acts like a barrier and the plastic cannot extrude. You know, 3D printing can be sometimes really frustrating, especially if you don’t know the reason for the problem. I’ve had several issues along the months, I’m going to post about typical issues with my Makerbot soon (problems with the Delrin plunger, broken cables, SD card reading errors and wrong plastic pulleys… c u next time;)
