Amos Dudley wanted to improve his smile but didn’t want to pay thousands of dollars for Invisalign, so he 3D printed his own orthodontic aligners.
I took a mold of my teeth with some cheap alginate powder, Permastone, and a 3d printed impression tray, to get a better picture of what was really going on. Notice LI-r (right lateral incisor) projected outward, and CI-r (right central incisor) depressed inward and overlapping.
At the time of writing this, I’m an undergrad, which means that a) I’m broke, and b) I have access to expensive digital fabrication tools - definitely an unusual dichotomy. I was researching [name brand clear-aligner treatment], and I ran across a photo that caught my eye.
Those look like the layer striations from a 3D print!
What is to stop someone, who has access to a 3D printer, from making their own orthodontic aligners?
Update: Unsurprisingly, orthodontists feel that DIY dentistry is not such a great idea.
Belli notes, “He moved these teeth in only 16 weeks. You can cause a lot of problems with that. If you move a tooth too fast, you can actually cause damage to the bone and gums. And if you don’t put the tooth in the right position, you could throw off your bite,” leading to additional damage and wear on the teeth.
The Neues Museum in Berlin is the current home of the bust of Queen Nefertiti, a singular piece of ancient Egyptian sculpture. A pair of artists went to the museum, did a 360° scan of the bust without the museum’s permission, and have made the resulting high-resolution 3D model available to all.
In lieu of the contested original, a 3D-printed copy of the bust made from the model is now on display in Egypt at the American University of Cairo. (via hyperallergic)
Update: There’s cause to be skeptical about how the 3D scan of Nefertiti was accomplished and the artists are being a little vague as to how they did it. The video shows the artists using a Kinect Xbox controller but a Kinect scan can’t deliver the resolution level of the 3D model. Perhaps it was stitched together using a bunch of photos? Or maybe they hacked into the museum’s files and took their model?
The last possibility and reigning theory is that Ms. Badri and Mr. Nelles elusive hacker partners are literally real hackers who stole a copy of the high resolution scan from the Museum’s servers. A high resolution scan must exist as a high res 3D printed replica is already available for sale online.
The Free Universal Construction Kit is a collection of almost 80 adapters between various construction toys like Lego, Lincoln Logs, Duplo, and K’nex (10 toys in all). The kit is available as freely downloadable designs for your 3D printer. The MoMA announced the acquisition of the Construction Kit for their permanent collection earlier this year.
The Venus de Milo’s arms are lost to history but that hasn’t stopped historians and scholars wondering what exactly she was doing with them when the statue was carved. In order to test out a theory that Venus was spinning thread, Virginia Postrel hired designer and artist Cosmo Wenman to construct a 3D model of Venus de Milo.
Ted Power’s Citibike key broke, so he pried the chip out of it and 3D printed a new key with a built-in bottle opener.
Power used Shapeways’ printing service to make the key. His exact key isn’t publicly available on the site, but you can print this cool multi-tool replacement. (via @dens)
This is magnificent. The little floppies!
And you can totally build your own with these instructions. Case is 3D printed and the chip & software run on the Arduino platform. So cool! (via devour)
Artist Aki Inomata builds fanciful new houses for hermit crabs.
Miniature windmills, churches, and even entire cities jut from the surface of her 3D-printed shells, which are modelled upon CT scans of abandoned crab shells and then recreated in transparent resin. Inomata then allows the homeless crabs to inspect the shelters at their leisure — she says “most hermit crabs don’t even glance at” them, but occasionally one of the creatures finds its dream real estate and settles in.
Yobi3D is a search engine for finding 3D objects. Here’s a search for “horses”:
This is pretty neat…all the objects are zoomable and rotatable in the browser. (via prosthetic knowledge)
Sometime around 1918 in Buenos Aires, Marcel Duchamp designed a chess set:
Sometime earlier this year, Scott Kildall and Brian Sera used archival photos of the hard-to-find set, turned them into 3D models of the chess pieces, and made a pattern for 3D printing your own set:
The community at Thingaverse is already busy making interesting variations of Duchamp’s set…look at this one:
Something tells me Duchamp would have loved this whole thing.
Update: Welllllll, Duchamp may have loved this, but his estate definitely did not. Duchamp’s estate sent Kildall and Sera a cease and desist letter, forcing them to remove the 3D models from Thingiverse. Which, the irony! So, Kildall and Sera, riffing on Duchamp’s mustachioed Mona Lisa, have created a set of six 3D-printed chess pieces with mustaches modeled on the Duchamp set. Fantastic.
Vice made a 24-minute documentary film about Cody Wilson, who is designing a semi-automatic weapon that can be printed out on a 3-D printer. You just download the plans, print it out, and there you go.
“Gun control is a fantasy” indeed.
