A three-dimensional (3D) printing system for manufacturing a three-dimensional article includes a resin vessel for containing a volume of photocurable resin having a resin upper surface, an imaging system configured to define a build plane, a build plate having a build plate upper surface, a build plate positioner, a sensor configured to generate a signal indicative of a fluid-related vertical position of one or more of the resin upper surface and a component of a volume compensator (VC), and a controller. The controller is configured to (1) operate the build plate positioner to vertically translate build plate upper surface, (2) concurrent with operating the build plate positioner, receiving the signal from the sensor, (3) analyze the signal to determine a build plate geometric signature, and (4) determine or suspend a build plan for building the 3D article based upon the determined geometric signature.

System and method for determining a build plan based upon an analyzed build plate geometric signature

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.
