Whether you’re a beginner or a pro, our CNET expert found the best 3D printers for performance, reliability and value.

A group of North Texas doctors and scientists printed part of a human femur—the longest and strongest bone in the body—that mimics the strength, flexibility and overall mechanics of a real ...

Color gradient filament is fun stuff to play with. It lets you make 3D prints that slowly fade from one color to another along the Z-axis. [David Gozzard] wanted to do some printing with this effec… ...

We love 3D printing. We’ll print brackets, brackets for brackets, and brackets to hold other brackets in place. Perhaps even a guilty-pleasure Benchy. But 3D printed shoes? That’s where we ...

A Texas company — driven by a mission to create faster, better and more affordable housing — is 3D printing homes. It's also working with NASA to 3D print on the Moon. Lesley Stahl reports.

More affordable than ever, 3D printers are booming for personal, professional, and educational use. Here's everything to know before you buy one, along with the top models from our hands-on testing.

An air-gap winding (air-core) stator for a 1000 kW high temperature superconducting synchronous motor is designed by the Global R&D Center, TECO-Westinghouse Motor Company. This motor uses HTSC wire ...

The influence of slot-and-pole-number combinations on the leakage inductance of double-layer fractional-slot concentrated nonoverlapping winding (i.e., tooth-coil winding) permanent-magnet synchronous ...

3D printing filament is a fundamental component of fused deposition modeling (FDM) and other extrusion-based 3D printing processes. Whether you’re a hobbyist, engineer or manufacturer, selecting the ...
