Abstract: A three-dimensional (3D) printing system for manufacturing a 3D article includes a resin vessel, a build plate, a plate support, a hook subsystem, an elevator subsystem, an imaging subsystem, and a controller. The build plate has an upper surface and extends from a proximal end to a distal end. The hook subsystem includes a hook. The controller is configured to: (a) Operate the elevator subsystem and the imaging subsystem to fabricate the 3D article. (b) Operate the elevator subsystem to raise the 3D article above photocurable resin in the resin vessel. (c) Operate the hook subsystem to configure the hook to be engaged with the proximal end of the build plate. (d) Operate the elevator subsystem to impart a vertical separation distance between the proximal and distal ends of the build plate. The vertical separation distance defines an angular tilt of the 3D article to facilitate draining of residual photocurable.

Abstract: A three-dimensional printing system for fabricating or manufacturing a three-dimensional article includes a support plate, a resin containment structure, an actuator, a light engine, a support tray coupled to a movement mechanism, and a controller. The resin containment structure is supported by the support plate and includes a lower substructure that is moveably coupled to an upper substructure. The upper substructure defines an upper central opening that is closed by a transparent sheet. The lower substructure defines a lower central opening that is closed by a transparent plate. The actuator is affixed to the support plate and configured to rotate the upper substrate about the hinge between a (1) a raised position in which the transparent plate contacts and supports the transparent sheet and (2) a lowered position in which the transparent plate is out of contact with the transparent sheet.
