Abstract
Systems and methods for making it easier to remove support structures printed in conjunction with printing an object using stereolithographic additive manufacturing are disclosed. In some exemplary embodiments, one or more interfaces between the printed object and the support structures are modulated to allow for easy separation between them, in some instances even when the object and support structures are made from the same material. Various modulation techniques are disclosed, including adjusting an intensity of exposure to light at interfaces between the object and support structures, and using two materials where one material cures at two wavelength ranges and the other material only cures at one of the two wavelength ranges. Other systems and methods that allow for easy separation of part and support structure are also described.
