Beschreibung
Zusammenfassung:	A direct metal laser melting (DMLM) system includes a rotatable base, and a build plate mounted on and supported by the rotatable base, where the build plate includes a build surface. The DMLM systemalso includes a first actuator assembly, a first powder dispenser disposed proximate the build plate and configured to deposit a weldable powder on the build surface of the build plate. In addition, the DMLM system includes a first powder spreader disposed proximate the build plate and configured to spread the weldable powder deposited on the build surface of the build plate, and a first laser scanner supported by the first actuator assembly in a position relative to the build plate, such that at least a portion of the build surface is within a field of view of the first laser scanner. The first laser scanner is configured to selectively weld the weldable powder. The first laser scanner is further configured to translate axially relative to the build surface on the first actuator assembly. 直接金属激光熔化(DMLM)系统包括可旋转基座，
