Adjustable build envelope for powder bed fusion machines

The adjustable build envelope for powder bed fusion machines includes a frame in the build chamber having four movable sides, a base and two motors with lead screws. The motors are placed at an angle of 45° with respect to the side of the frame, so that as the motors rotate the lead screws, the two sides of the frame slide in opposite directions. The sides move inward with the help of guide pins and dovetail grooves, thereby reducing the build envelope volume. For large builds, both motors rotate in the reverse direction to increase the build envelope volume. By changing the build envelope volume according to the given build size, powder waste is reduced.
