  2. The world’s first 3D-printed gun

    Technology is a lovely thing, but sometimes it scares the bejeezus out of us. This working 3D-printed gun is one such case.

    Gun enthusiast “HaveBlue” has documented in a blog post (via the AR15 forums) the process of what appears to be the first test firing of a firearm made with a 3D printer.

    Before you go about locking yourself in your closet, you should know that the only printed part of the gun was the lower receiver. But, according to the American Gun Control Act, the receiver is what counts as the firearm.

    HaveBlue reportedly used a Stratasys 3D printer to craft the part, assembled it as a .22 pistol and fired more than 200 rounds with it.

    The tester then attempted to assemble a rifle with the part and a .223 upper receiver but had “feed and extraction issues.” The problem may not in fact be with the 3D-printed part, though, as the issues remained when a standard aluminum lower was used.

    3D printer gun designs have been floating around the Internet for some time now, but HaveBlue seems to be the first to take it to the next level.

    *”Our entry into the Siri design competition, an accessory which slides
    onto the iPhone and serves as the ‘face’ of Siri. The androgynous face has
    a wry, elusive smile suggesting the machine knows something that the user
    does not. Behind Siri’s all-knowing gaze, the glow of the iphone screen is
    visible through the sculpture, and the main buttons are still accessible
    even when the screen is obscured. The design, when placed over the iphone,
    forces the user to interact with Siri instead of tapping on the screen to
    engage commands. For more complicated tasks requiring the screen however,
    the phone can easily be slipped out of the top of the case.”*

  6. 3D scans from the Met-3D hackathon

    Art that everyone can remix from afar

    Indian Girl by Erastus Dow Palmer

    Last week, the Metropolitan Museum of Art held an event to make 3D scans and prints of works from throughout the museum. Participants used digital cameras andAutodesk’s 123D Catch to generate the 3D models, and then printed them usingMakerBot Replicators.

    Several models were uploaded to Thingiverse shortly afterwards, and today the uploads continue. The sculpture above – Indian Girl by Erastus Dow Palmer – is new as of about an hour ago. Well, the scan is new at least, the original is from about 1850. :)

    Here are a some more scan vs. original comparisons I put together:

    Luisa Deti by Ippolito Buzio (1562-1634)

    Marble statue of a lion

    They might seem a bit crude at first, but keep in mind that these are untextured 3D models produced from photographs (using free software, no less). That’s always going be less fancy than an expensive laser scan, but way more accessible.

    If you’d like to download the models for 3D printing, make sure you follow the Met’s user page on Thingiverse, here: http://www.thingiverse.com/met

  7. The Free Universal Construction Kit

    Ever wanted to connect your Legos and Tinkertoys together? Now you can — and much more. Announcing the Free Universal Construction Kit: a set of adapters for complete interoperability between 10 popular construction toys.

    In addition to the Kit itself, we also offer for download this attractive B1 poster (4.5MB PDF, in two versions: gray background / white background).

    Video by Riley Harmon for F.A.T. Lab + Sy-Lab.

    F.A.T. Lab and Sy-Lab are pleased to present the Free Universal Construction Kit: a matrix of nearly 80 adapter bricks that enable complete interoperability between ten* popular children’s construction toys. By allowing any piece to join to any other, the Kit encourages totally new forms of intercourse between otherwise closed systems—enabling radically hybrid constructive play, the creation of previously impossible designs, and ultimately, more creative opportunities for kids. As with other grassroots interoperability remedies, the Free Universal Construction Kit implements proprietary protocols in order to provide a public service unmet—or unmeetable—by corporate interests.
