At last, a simple 3-D printer for metal

Used to produce three-dimensional objects of almost any type, across a range of industries, including healthcare, aviation and engineering, 3-D printed materials have come of age during the last decade. Research published ...

Holding stellar nurseries in your hands

Astronomers can't touch the stars they study, but astrophysicist Nia Imara is using 3-dimensional models that fit in the palm of her hand to unravel the structural complexities of stellar nurseries, the vast clouds of gas ...

Additive manufacturing, explained

Additive manufacturing is the process of creating an object by building it one layer at a time. It is the opposite of subtractive manufacturing, in which an object is created by cutting away at a solid block of material until ...

Researchers 3-D print electronics and cells directly on skin

In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield ...

NASA team moves closer to building a 3-D printed rocket engine

A NASA team moved a step closer to building a completely 3-D printed, high-performance rocket engine by manufacturing complex engine parts and test firing them together with cryogenic liquid hydrogen and oxygen to produce ...
