A Route for Avoiding Defects During Additive Manufacturing
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 of a part, a keyhole-shaped cavity in the melt pool can result. Pores, i.e., defects, form at the bottom of the keyhole. New research published in Science reveals how the pores are generated and become defects trapped in solidifying metal.

Elastic motion makes click beetles click, study finds
Illinois researchers Aimy Wissa, Marianne Alleyne and Ophelia Bolmin studied the motion of a click beetle’s jump and present the first analytical framework to uncover the physics behind ultrafast motion by small animals.

CHAMPAIGN, Ill. Click beetles can propel themselves more than 20 body lengths into the air, and they do so without using their legs. While the jump’s motion has been studied in depth, the physical mechanisms that enable the beetles’ signature clicking maneuver have not. A new study examines the forces behind this super-fast energy release and provides guidelines for studying extreme motion, energy storage and energy release in other small animals like trap-jaw ants and mantis shrimps.
