Abstract:
Various embodiments described herein provide a method of making an object from a three-dimensional geometry file and a light polymerizable resin on a light-transmissive window by projection of light through the window in a bottom-up stereolithography process. The method may comprise: slicing the file into a series of sequential images. Temperature fluctuations in the resin may be calculated for at least some of the sequential images upon light polymerization thereof based on sequential exposure of the resin to light, the light corresponding to the series of sequential images. During producing of the object, the production may be modified based on the calculated temperature fluctuations by: (i) reducing production speed during at least a portion of the production; (ii) activating a window cooler during at least a portion of the production; or (iii) increasing production speed during at least a portion of the production.
