Ingested nanoparticles could be harmful to health

(PhysOrg.com) -- Billions of engineered nanoparticles in foods and pharmaceuticals are ingested by humans daily, and new Cornell research warns they may be more harmful to health than previously thought.

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 ...

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 ...

New technology could revolutionize 3-D printing

A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility (NIF) can be used to 3-D print metal objects faster than ever before, according to a new study by Lawrence ...

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 ...
