Abstract
Disclosed are selective deposition based additive manufacturing systems () and methods for printing a 3D part. Layers of a powder material () are developed using one or more electrostatography-based engines (). The layers () are transferred for deposition on a part build surface. For each of the layers (), the part build surface is heated to a temperature within a range between a flowable temperature and a thermal oxidation threshold to form a flowable part build surface, and the developed layer () is pressed into contact with the flowable build surface () to heat the developed layers () to a flowable state and form a new part build surface () which is fully consolidated. The new part build surface () is then cooled to remove the heat energy added during heating step before repeating the steps for the next developed layer.
