Abstract
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.
