Abstract
A method for printing a 3D part in a layer-wise manner includes providing a pool of polymerizable liquid in a vessel over a build window and positioning a downward-facing build platform in the pool, thereby defining a build region above the build window. The method includes selectively curing a volume of polymerizable liquid in the build region by imparting electromagnetic radiation through the build window to form a printed layer of the part adhered to the build platform and actively cooling the build window to remove energy imparted by the electromagnetic radiation and the polymerization reaction of the polymerizable liquid such that the printed layer is between about 1° C. and about 30° C. below an average part temperature prior to raising the print layer and printing the next layer.
