How do 3D printers work? What's the impact on our economy? How expensive are they compared to traditional manufacturing? We take a three-dimensional look at the world of additive manufacturing.

I bought a 3D printer a few years ago, primarily with the aim of printing functional items to use around the house. It has ...

How a 3D printer works can vary depending on the type of printing it's doing. Use this guide to understand the variations in materials and technique.

3D printing has already changed the game for manufacturing specialized products such as medical devices but the real revolution will come when designers start to rethink the shapes of objects.

A new technique enables makers to finely tune the color, shade, and texture of 3D-printed objects using only one material. The method is faster and uses less material than other approaches.

Researchers have developed a new laser-based process for 3D printing intricate parts made of glass. With further development, the new method could be useful for making complex optics for vision ...

While consumer-grade 3D printers may be adequate for making things like models or curios, they're not always up to the task of creating objects that stand up to real-world use. That could be about ...
