Abstract
A 3D metal printing machine or apparatus includes a welder that deposits one or more layers of metal, and a powered cutting tool that may be utilized to remove a portion of the metal deposited by the welder after the metal has solidified. Numerous layers of metal can be deposited and machined to form complex 3D metal parts. During fabrication, a part may be formed on a support whereby the part can be fabricated by welding and machining operations without removing the part from the support. A 3D CAD model of a part may be utilized to generate code that controls the 3D metal printing apparatus. A measuring device such as a probe or laser scanner may be utilized to measure the shape/size of parts in the 3D metal printing machine.
