Abstract: The widespread adoption of laser powder bed fusion (LPBF) additive manufacturing is hampered by process unreliability problems. Modeling the melt pool behavior in LPBF is crucial to develop ...

Two photon polymerization has now moved from “on cells” to “inside cells”, opening a strange, new frontier.

When a laser experiment fails to produce the expected flash of light, most researchers would assume something went wrong with the hardware. In this case, the missing signal turned out to be the most ...

Abstract: In this article, an inexpensive beam homogenizer is designed to transform the laser beam with irregular intensity into a uniform square beam with a large size, thus eliminating the ...
