Abstract
A method of additive manufacture is disclosed. The method can include providing an enclosure surrounding a powder bed and having an atmosphere including helium gas. A high flux laser beam is directed at a defined two dimensional region of the powder bed. Powder is melted and fused within the defined two dimensional region, with less than 50% by weight of the powder particles being displaced into any defined two dimensional region that shares an edge or corner with the defined two dimensional region where powder melting and fusing occurs.
