Normally, you have a choice with PCB prototypes: fast or cheap. [Stephen Hawes] has been trying fiber lasers to create PCBs. He’s learned a lot which he shares in the video below. Very good ...

Perhaps best of all, there appears to be nothing here that couldn’t be also performed outside the lab by anyone with enough Kapton and copper, and a fiber laser. We’re looking forward to where ...

The fiber lasers are arranged in a compact hexagonal structure and coherently combined to generate illuminating light fields.

The laser selectively cures the HSQ, removing the uncured HSQ and leaving a 3D-printed silica glass structure on the fiber tip. Results show that the work solves the problem of high-temperature ...
