3D printed generative jewellery with affordable desktop FDM printers

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.

Actually a dear friend of mine runs gigamax3d.com and GigamaX3D facebook page.
They are the official european distributors of ESUN filaments and Velleman 3D printers. They sell nice quality ABS/PLA/HIPS/PVA 3d printing filaments with 1.75 and 3 mm diameters in 1 kg spools in 16 vibrant colors, which I’ve already tested on my Replicator2 and they are all good (I’ve had some serious troubles with 3d printer filament diameter issues before).

They also carry consumer and prosumer desktop 3D printers like the Leapfrog Creatr or the Tricolor Mendel RepRap model and also offer print on demand services and training/education workshops. A lot of RepRap parts and electronics are available on stock as well. Gigamax 3D printing workshops offer an impressive scope of standalone desktop 3D printing technology, the Leapfrog Creatr dual extruder model, tricolor Mendel, K8200, Reprap Huxley to name just some of the best ticket items being put to use and build by this busy little center.

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;)
