A route for avoiding defects during additive manufacturing — ScienceDaily

Laser powder bed fusion is a dominant additive manufacturing technology that has yet to reach its potential. The problem facing industry is that tiny bubbles or pores sometimes form during the printing process, and these pores create weak spots in finished products. When a slow-speed, high-power laser is melting metal powder during the 3D printing […]

A route for avoiding defects during additive manufacturing

Artwork showing the boundary and origin of keyhole porosity. On the left side of the figure, the keyhole porosity boundary in the laser power – scan velocity space is sharp and smooth. On the right side, around the porosity boundary, the critical keyhole instability releases acoustic waves (shock waves) in the melt pool. The waves […]

Low temperature, scalable manufacturing of flexible energy harvesters

A simple approach to create high performance thermoelectric materials, which would allow one to turn their body heat into electricity. Imagine mixing together a few solutions and creating a material that would allow one to turn their body heat into electricity. A simple approach to energy harvesting is within reach now that an interdisciplinary team […]
