Additive manufacturing, or 3D printing, is normally a one-way street. In a digital light processing (DLP) printer, a ...

A new type of "ink" makes it possible to 3D print electrochemically switchable, conducting polymers using a light-based ...

Concrete 3D printing reduces both time and cost by eliminating traditional formwork, the temporary mold for casting. Yet most ...

A 3D-printable ink can change color with electricity, letting people make pixel displays, soft robots, and 3D electronic devices.

It is a fact of life that 3D printed parts from an FDM (fused deposition modeling) printer have weaknesses where the layers join. Some of this is due to voids and imperfect layer bonding, but you can ...

A new additive manufacturing route creates carbon fiber silicon carbide mirrors that unite low weight, strength, and sub-nanometer smoothness, reaching 97 percent visible reflectance for space optics.

The concept of rheology refers to a branch of physics that studies fluids. It examines how materials behave when they flow or ...

3D printing has changed the world since its inception, influencing everything from simple plastic prototypes to sophisticated, life-saving medical implants. It began in the 1980s as a way to fuel a ...

[Slant 3D] knows a lot about optimizing 3D prints so that they can be cranked out reliably with minimal need for post-processing, and in this short video he uses a cube as a simple example of how a ...
