Abstract
A configurable build volume system for a powder bed fusion manufacturing process includes a chamber wall defining a chamber, the chamber wall extending in the X-, Y-, and Z-axis directions, a plurality of build platforms enclosed within the chamber, a plurality of adjustment mechanisms coupled to the plurality of build platforms such that each build platform is coupled to a separate adjustment mechanism, a sensor mounted within the chamber and configured to capture data regarding a Z-axis position of each of the plurality of build platforms, and a controller in electronic communication with the plurality of adjustment mechanisms and the sensor. The controller receives the Z-axis position data and generates a plurality of control signals to adjust a Z-axis position of each of the plurality of build platforms and each of the plurality of build platforms is actively and independently controlled by the controller.
