Ryan sez, "This is the spiral skull that I created in Zbrush and got printed in strong, flexible nylon. It's being featuring at the 3D Printshow in NYC which wraps up Saturday." It's called "Mortal Coil" (clever!) and it's €66.59 and up on Shapeways. If this sort of thing excites and amuses you as much as it does me, don't miss the fan-folded paper slinkoid sculptures of Li Hongbo.
SainSmart PLA works fantastically in my Makerbot Replicator 2.
I tried ordering plastic from Makerbot directly but delays on every color I wanted led to me check for other sources. Seems this complaint is common. Guess what? I saved $11/spool and got every color I wanted 2 days later.
Thank you Amazon Prime and the power of internet forums! There are lots of providers of PLA but people have a lot of trouble sorting them. From varying thickness of the strand's diameter to differing melting points of the plastic there is a lot to look out for. I found the SainSmart stuff to work very reliably.
After you order the plastic you will need to print a new spool holder. This pattern worked fine for me (I did rotate the model on the build plate, so it didn't build straight up!) Also, I read around on the internet and then experimented with extruder temperatures. The Replicator 2's default setting of 230F is too hot for the SainSmart, I find 215F works much, much better in my home.
I've tried Black, Red, Blue, Pink and Silver/Grey. So long as your build plate is level and the extruder is clear SainSmart works great!
Toronto's Metro Reference Library has unveiled its new makerspace, which sports 3D printer and scanners, Arduino and Raspberry Pi kits, and digital AV production gear. They've also lured the Toronto Mini-Maker Faire into relocating to their space. The library's makerspace will over classes and workshops on programming, hardware hacking, and repairing your electronics. It's a great all-ages/all-comers complement to Toronto's existing makerspaces, including Hacklab, Site3, and Makerkids.
The location couldn't be any better, either. I love Metro Ref. When I was 14, I dropped out of high-school without telling my parents and started taking the subway down to Yonge and Bloor every day, spending all day at the reference library, spelunking in the shelves, subject indices and (especially) the newspaper microfilm, which was amazing. And I've always loved the idea of makerspaces in libraries: as I wrote during last year's Freedom to Read week, "We need to master computers — to master the systems of information, so that we can master information itself. That's where makers come in."
Yesterday marked the expiry of US Patent 5597589, "Apparatus for producing parts by selective sintering." This is one of the core patents in the 3D printing world -- the patent that allows 3D printer companies to charge more for fine nylon powder than Michelin-starred restaurants charge for filet mignon. The high cost of consumables in 3D printing has been a major barrier to innovation in the field -- selective laser sintering produces a fine finish that the patent-free fused deposition modeling technique used in Reprap-style printers can't match -- and now the brakes are coming off.
However, there are still lots of patents (including some genuinely terrible ones) in the 3D printing world, so the expiry of 5597589 doesn't necessarily mean that we'll see a flood of cheap printers and cheaper feedstock -- given the murkiness of the overlapping patent claims and the expense of litigating each one of them, radical new entrants into the field are still facing a lot of risk that has nothing to do with making great products at a fair price.
In a good piece on 3D Print, Eddie Krassenstein speculates about the scary supplementary laser-sintering patents lurking in the wings, pointing out that Stratasys (the major competitor of 3D Systems, who owned 5597589) didn't design their entry-lever printers to use SLS, even though they knew that the patent would be expiring in early 2014. Krassenstein suggests that this means that Stratasys knows about some other gnarly and deadly patent that would torpedo them if they went SLS.
But I'm a lot less convinced than Krassenstein is about the potential of a competitor taking the risky step of making a SLS printer that sticks to the claims in 5597589. Virtually every technical idea is covered by a stupid, overbroad patent, and yet people start businesses every day that open them to legal liability from a troll or an entrenched incumbent. If the potential for a patent suit was, in itself, a sufficient deterrent to raising capital and starting a business, we wouldn't see any startups. And a company that sticks to the claims in 5597589 has a powerful weapon in any patent suit: the USPTO granted 5597589 20 years ago, and so if they granted overlapping patents since, they were manifestly in error, a matter that is relatively (in patent terms, anyway) easy to prove.

Bunnie Huang is a virtuoso in hardware engineering, and a hero of the open source hardware movement. In this Make post, he documents how he and Sean "xobs" Cross prototyped a laptop that was open and transparent to a very great degree, secure against all attacks short of dopant-level hardware trojans. The post -- and the photos of the gloriously fuggly laptop, which they dubbed "the Novena Project" -- is part requirements document, part philosophical statement, and part engineering text. I love Bunnie's reasoning for wanting an amazing, open laptop: he spends the majority of his waking hours with it, so he wants it to be as amazing as possible, and it's worth him spending the time and money to get there. I also love the requirements he sets out for genuine "openness" (I put some of these after the jump, below). Most of all, I love how this thing looks: rough-hewn, gloriously unfinished with its 3D printed panels, and as bursting with potential as the Colossus.

In Paging Dr. MacGyver, Julian Smith profiles a wide range of medical makers, from patients to carers to doctors, each of whom has homebrewed some important piece of medical or therapeutic equipment. From DIY prosthetic limbs to the wonderful Dr Oluyombo Awojobi, whose rural Nigerian clinic is graced with a collection of his brilliant improvised devices built from scrap, Smith makes the case for a networked world where medical needs, ingenuity, and a spirit of mutual aid and collaboration are offering new opportunities for making each other healthy.

3D Systems' display at this year's CES included the ChefJet 3D printer, whose output medium is flavored (chocolate, vanilla, mint, sour apple, cherry and watermelon) sugar (it's softened with water and set with alcohol). The monochrome version is less than $5,000, and a full-color version will ship later this year at less than $10K. It's marketed at the food industry, and comes with simple modelling software. The technology's come a long way since the Evil Mad Scientists came up with the CandyFab five years ago. (via Singlarity Hub)
Jeroen Domburg's friend was having a 25th birthday party at which jello shooters were to be served. Jeroen decided to liven these up by creating a 3D printer that inserted a needle into each shot and injected an ink made from banana liquor, food colouring and corn starch in 3D patterns like cubes and spirals. Even cooler: the main body of the electronics in the printer were harvested from superannuated DVD and CD drives, and the firmware for the printer is free software (TGZ) for your pleasure.
Derryl Murphy sez, "My son is home sick and found this video showing a 3D printer ItsJustJumby created for working inside the world of Minecraft. The engineering is way beyond the two of us, but we both still find it amazing and fascinating."
I could watch this all day. The description's actually very clear, and extremely clever. Great engineering smarts on display.

We're big fans of Dan Hillier's work around here -- the iconic, instantly recognizable grotesque Victorian collages. Now he's branched out into 3D printing. He writes: "I recently collaborated with a 3D printing design consultancy called Modla, for The Other Art Fair. Having met with their Creative Director, Jon Fidler, we worked on the creation of a 3D version of my work, 'Nothing Matters'. The piece is now available in a limited edition of 20." (Thanks, Dan!)
