Additive manufacturing process and device by deposition of molten metal wire under concentrated energy with control of the metal wire feed speed

Abstract

A concentrated energy fused wire deposition additive manufacturing process in which a distal end (13A) of the wire (13) is melted with the concentrated energy source (12B) to create a fused end (FE) for depositing the fused metal material from the fused end (FE) onto a support (S); the position of an impact point (PI) of the fused end (FE) on the support (S) is detected; the distance D between the position of the impact point (PI) and the position of the predetermined nominal melting point (PF) is determined; and the feed rate Vf is adjusted according to the distance D.
