Opis

The present work addresses the development a new exposure concept for Laser Powder Bed Fusion (L-PBF) based on a multispot-array generated by several fiber-coupled diode laser systems. A first demonstrator machine is developed, allowing for a systematic evaluation of the correlation between process parameters and resulting part quality. It is shown that parts with relative density of more than 99,5 % can be manufactured by that means.
