The layer-by-layer process of 3-D printing is a slower, more expensive, worse way of manufacturing than molding or subtractive manufacture.

This is no dot-matrix monster. It's a precision three-dimensional printer that lays down layers of liquid blue plastic to create 3-D models of "monkey" skulls (fossil primate skulls, actually).

The result of such patent disputes is that certain aspects of 3-D-printing technology remain available only to those who can afford the corporate-sold printers.

A 3-D printer that stands 4 m tall can rapidly print large structures thanks to its innovative cooling system (Science 2019, DOI: 10.1126/science.aax1562). Three-dimensional printing has long been ...

PLA filament is a great low-temperature printing filament that's easy to use, non-toxic, and suitable for beginners as well ...

A young startup called Relativity is pushing space technology forward by pushing 3D printing technology to its limits, building the largest metal 3D printer in the world.

With a little bit of plastic, and a lot of technical know-how, you can print anything you can imagine. Here are the best 3D printers of 2019.

They say rapid prototyping using 3-D printing is producing more innovative, higher-quality products — from custom-fitted bicycle helmets and prosthetics to better-sounding ear buds and loudspeakers.

For all the hype over three-dimensional printing, it’s still unclear exactly how and when it will have an impact on our daily lives.

For $400, the New Matter MOD-t, Printrbot Play and XYZPrinting da Vinci Jr. 1.0W make 3-D printing much more accessible to families and schools. But using them is still a project.

Most 3-D printer manufacturers compare their products to side-to-side-moving paper printers, but the three-armed DeltaMaker takes its design cues from high-speed manufacturing robots.

The best 3D printers for beginners offer simple setup, flexibility, and an intuitive interface to help get users up and printing.
