What it's like to be personally responsible for automating away someone's high-paid, high-skill job

When Erin Winick was a sophomore, she got a summer internship at a company where her manager offered her the opportunity to use her passion for 3D printing to streamline the company's mold-making process; but when she started consulting with "Gary," a 34-year veteran of the company who was responsible for the complex molding process, she realized that she was about to put him out of a job.

3D printed origami robots that crawl and grab when activated by magnets

A team at MIT’s Department of Mechanical Engineering and Department of Civil and Environmental Engineering have created a set of foldable, 3D printed robots that are doped with magnetic particles that are precisely aligned during printing; when triggered by a control-magnet they engage in precise movements: grabbing, jumping, rolling, squeezing, etc. Read the rest

Frozen Rat Kidney Shipping Container: The incredibly bounty of the NIH's 3D printables repository

3D printing arbitrary shapes without sprues, by embedding them in 3D-printed clear plastic

3D printing complex shapes is hard; the additive nature of most 3D printing means that the printer has to create sprues (struts that support parts of the structure during printing, which have to be removed later), or add in material that can be dissolved in a solvent bath after main production.

See how this 3D-printed gear turns clockwise no matter how it's cranked

Differential gears can be used for all sorts of interesting things, as YouTuber Maker's Muse demonstrates with this 3D-printed hand crank that only turns clockwise. Read the rest

Watch this delightful 3D zoetrope system with swappable animations

4-Mation is a product being developed by Kevin Holmes, Jonathan Scoon, and Charlie Round-Turner that features a spinner that accommodates different 3D-printed animations, like the leaping frogs above.

They also have this cute fish loop:

They plan to offer three models, from basic to deluxe:

4-Mation is a modular 3D Zoetrope kit that will be available in 3 models. It’s powered by 24 3Watt RGB LED strobes, precision timed by a microcontroller linked to an encoder motor. RPM(Strobe-rate), brightness, colour are all controlled from a phone app. The Android app (4-Mation) is already in the play store, iPhone app is in progress. Assemble the kit in about 1/2 hour then download and print one of our free animations – or design your own.Animations can be swapped in a minute.

They took it to a local school, where the response was tremendous:

A proposal to stop 3D printers from making guns is a perfect parable of everything wrong with information security

Many people worry that 3D printers will usher in an epidemic of untraceable "ghost guns," particularly guns that might evade some notional future gun control regime that emerges out of the current movement to put sensible, minimal curbs on guns, particularly anti-personnel guns. Read the rest

An algorithm that converts 3D meshes into machine-knitting patterns

A group of CMU researchers have created a generalizable approach to converting the model files generated by 3D design packages into knitting patterns that can be fed into a variety of computerized knitting machines, which then "print" the solid by knitting it. Read the rest
