Influence of the opto-mechanical chain on the energy provided by the laser spot to the material in laser powder bed fusion processes

The additive manufacturing machines used in laser powder bed fusion processes are composed of an opto-mechanical chain whose purpose is to focus the laser in the work plane to locally fuse the material with the required energy. The opto-mechanical…
