This 3D-Printed Working Model of a 787's Jet Engine Has Impressive Thrust

Given the challenges with precision, building functional machines with a household 3D printer isn’t easy. And that’s why it’s all the more impressive that someone on the RC Groups forum has used a 3D printer to make a fully-functional scale model of a Boeing 787’s GE-built turbofan jet engine. »8/31/15 10:25amMonday 10:25am

Kid Gets Awesome New Bionic Hand, Reminds Us Not Everything is Garbage

The stock market is tanking, North and South Korea are on the brink of war, and a cartoon character from a dystopian future is the most popular candidate for US President at the moment. But don’t despair. While most things are garbage, there are some things in the world that aren’t. Like this adorable kid who just got… »8/21/15 6:00pm8/21/15 6:00pm

NASA Released a Free 3D-Printable Model of the Curiosity Rover

Last year NASA started releasing 3D models of its probes and spacecraft that anyone could download and use to 3D print their own space fleet. That collection now finally includes a tiny replica of the Curiosity Rover that’s been exploring Mars since 2012, and will soon be exploring your desk as well. »8/14/15 3:08pm8/14/15 3:08pm

A 3D-Printed Electric Violin Sounds as Good as the Real Thing

Manufacturers are getting nervous as 3D printers are getting more and more skilled at perfectly recreating every last detail of a physical object. But on the flip side of that coin is the possibility that musicians might soon be able to afford their own copy of a Stradivarius—made from 3D- printed plastic, not wood. »8/11/15 9:30am8/11/15 9:30am

The World’s Biggest Free Form 3D Printer Is Being Used to Build Houses

The dream of 3D printing buildings is not a new one and, typically, it’s not a pretty one either. However, the visionaries at Branch Technology, a startup founded by architects in Chattanooga, Tennessee, want to change that—and they’ve built the world’s largest free form 3D printer to do it. »7/30/15 11:32am7/30/15 11:32am

Got Loose Change? 104 Pennies Help This Simple 3D-Printed Toy Walk

Invented in 1981 by John W. Jameson, the Walking Gyro is a simple toy that relies on a spinning flywheel and centrifugal forces to take tiny, but steady, steps. Mattel patented the design, but never actually put it into production. And now that its patent has expired, there’s a free 3D-printable version that anyone… »7/17/15 11:22am7/17/15 11:22am

A New 3D Printing Support Filament Easily Dissolves Away in Water

When 3D printing a particularly complex object, you often need to incorporate additional support structures into its design, given how the layer by layer additive process works. And with 3D systems new water soluble filament, those unwanted support structures can easily be dissolved away with a little H2O. »7/14/15 11:50am7/14/15 11:50am
