PRINTING BED, 3D PRINTER AND PRINTING METHOD EMPLOYING SUPPORTING SPOKES ACTIVATION TO AID 3D PRINTING

A printing bed (110) for a three-dimensional (3D) printer includes an upper surface (112) 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 (120). In response to the 3D object having an overhang with an an...

Zusammenfassung:	A printing bed (110) for a three-dimensional (3D) printer includes an upper surface (112) 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 (120). In response to the 3D object having an overhang with an angle that exceeds a predetermined threshold, the support structure (120) is configured to actuate from a first position into a second position to support the overhang.
