Title: Laser-assisted additive manufacturing

Abstract

Laser additive manufacturing apparatus, systems, and methods for the fabrication of high quality freeform high value structures. The apparatus, systems, and methods utilize a material powder having varying particle size and shape as raw material. It can also be adopted to use a wire as the feed material.
