Characterizing A Laser Used In Metal Additive Manufacturing Equipment
7/30/2020
In this application note, a developer of power-bed additive manufacturing systems needed a beam profiling system that could be used by their field technicians for setup and maintenance of customers’ lasers. The bulky water-cooled system they had been using was costly, and long lead times for sale and repair were unreasonable. Moving to a BeamGage® based system made setup quick and finding the focal spot location easy.
