  • MODEL BASED SUPPORTING SPOKES ACTIVATION TO AID 3D PRINTING
    Publication number: 20230382039
    Abstract: A printing bed for a three-dimensional (3D) printer includes an upper surface configured to have a plurality of droplets land thereon to form a first layer of a 3D object. The printing bed also includes a support structure. In response to the 3D object having an overhang with an angle that exceeds a predetermined threshold, the support structure is configured to actuate from a first position into a second position to support the overhang.
