3D Printing

3D printing technology has already made the move from engineering workshop to the home, and now it's set to make its mark in space. NASA has hot-fire tested 3D-printed rocket engine components, which have managed to withstand incredibly high temperatures and pressures to the same standard as traditionally manufactured parts. Being cheaper and faster to produce, 3D-printed parts have the potential to revolutionize the manufacturing of rocket engine components and save the space agency considerable time and money.  Read More

Left to right: the original, modified, and 3D printed armadillo figure stands on one foot ...

Sculpting in a digital environment gives you the freedom to create impossibly balanced models and gravity-defying poses, and that's all well and good until you go to 3D print it. Depending on the severity of the model's shape, size, and pose, it may need to be glued to a heavy pedestal or even modified just to remain upright. That's a headache that's going away with an ingenious software solution called Make It Stand that quickly and easily optimizes a model's internal volume to balance it out, even when posed precariously.  Read More

Fundamental to the Internet of Things is the idea that objects must be uniquely identifiable. RFID chips are perfect for assigning objects a digital fingerprint, at least so far as traditional manufacturing goes. But with the rise of 3D printing, incorporating an RFID chip into your object means interrupting the printing process. Now, scientists have come up with a way to 3D print a unique tag, called an InfraStruct, inside the object as it's being printed, and it's made possible by the slowly emerging field of terahertz imaging.  Read More

The LEGObot still has some wobble, but Krueger is hoping tighten the X and Y axes soon, ma...

As the 3D printing revolution continues, prices of 3D printers have continued to fall, with devices such as the Buccaneer 3D printer available for under US$400. But even that is still too expensive for many people – students in particular. That's why Matthew Krueger, also known as matstermind at instructables.com, has created a 3D printer for next to nothing from everyone's favorite childhood toy, LEGO.  Read More

Ebay embraces 3D priting with its Ebay Exact app

Ebay has teamed up with a host of 3D printing specialists to launch an iOS app named ebay Exact which lets users customize iPhone cases, jewelry and other odds and ends.  Read More

Star Trek's Mr. Scott will have fewer reasons to panic as the day comes closer when even rocket engines can be cranked out on 3D printers. In recent tests, NASA and Aerojet Rocketdyne fired a rocket engine injector at NASA's Glenn Research Center in Cleveland, Ohio that was made using a 3D printer. The project, done in collaboration between NASA and private industry, aims at speeding up the manufacture of rocket components while reducing costs as well as eventually printing them in space.  Read More

Twinkind's 3D scanning process is as quick and painless as having your photo taken

Now that you can be scanned and 3D-printed in miniature form, two-dimensional portraits seem so last century. Of course, this novelty is way more expensive than a photograph, but now a company called Twinkind located in Hamburg, Germany is offering a 3D portrait service where the lengthy scanning process has been made as quick and painless as having a photo taken. You can even scan your pets, as they don't need to stay still for 20 minutes at a time!  Read More

3D printing has started to involve everything from custom plastic casts to duck's feet. Now, researchers at North Carolina State University have developed a 3D printing technique that can create a variety of stable free-standing structures from liquid metal at room temperature.  Read More

If, like me, you've always felt that your books, record collection and years' of otherwise accumulated matter was lacking flight capability, you might be interested in Jasper van Loenen's Drone It Yourself project which turns more or less anything into a quadrotor drone with addition of a few motors and a control unit.  Read More
