Abstract
An AM apparatus for an AM process is provided. The AM apparatus includes a build chamber with a build plate to support one or more parts built with a powder, during a build operation. The AM apparatus further includes a laser assembly operable to deliver a melting laser beam, to melt and fuse the powder used to build the one or more parts. The AM apparatus further includes a part detachment assembly, separate from the laser assembly and operable for a cutting operation. The part detachment assembly includes one or more laser beam delivery apparatuses, each operable to deliver a cutting laser beam, and a part holder apparatus. During the cutting operation, the part holder apparatus holds the one or more parts, and each of the laser beam delivery apparatus(es) delivers the cutting laser beam, to detach the one or more parts from the build plate within the AM apparatus.
