3D Printing

In the world of ugly shoes, we've had some real bangers. Now there's the new Syntilay, the world's first entirely AI-designed and 3D-printed piece of thermoplastic polyurethane to call itself a shoe.

If you spot a snazzy silver ebike at CES this week, you should know that it's more than just a pretty face. It's the 3D-printed Titanium Zero, and it sports what is claimed to be the world's smallest, lightest, highest-torque-density motor.

Leading 3D printing firm Icon has revealed plans to create an ambitious new 3D-printed community for homeless people in Texas. The project will provide 100 safe and comfortable residences to those who need them most.

Like most high-end bicycle makers, Colnago once made all its bikes out of steel, but has since switched to carbon fiber. For its 70th anniversary, however, the Italian marque is revisiting steel with the partially 3D-printed limited-run Steelnovo.

3D printers have been used to create everything from tiny houses to US marine barracks, and now we can add teardrop camper to the list too. The Discover 3D sleeps three and includes a tailgate galley, plus some optional off-the-grid tech.

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or even special fabrication technology.

Rocket Lab's Neutron is the largest composite rocket ever made. It used to take a large team several weeks to hand-layer that much carbon fiber – but with the company's new Automated Fiber Placement (AFP) machine, it can now be done in a single day.

Until now, most 3D-printed architecture has been focused on housing or research projects. However, the burgeoning technology has come to the retail sector in a big way with a new 3D-printed extension for Walmart.

Billed as the world's first 3D-printed hotel, Icon's El Cosmico is currently rising in the Texas desert. The ambitious project will include vacation homes and shared amenities – plus some permanent starchitect-designed residences for sale too.

Using a 3D printer that works with molten glass, researchers forged LEGO-like glass bricks with a strength comparable to concrete. The bricks could have a role in circular construction in which materials are used over and over again.

We've seen 3D-printed titanium bars, stems and frame components, but the Reactor Aero takes the concept a whole lot further. Made by the No. 22 Bicycle Company in upstate New York, it's being billed as the world's first 3D-printed titanium road bike.

In an experiment that sounds about as safe as bobbing for fries, ESA carried out the first-ever 3D metal printing in space aboard the International Space Station (ISS). Built with Airbus, the Metal 3D Printer completed the first of four test shapes.
