The difference betwen DLP 3d printed parts and FDM 3d printed parts is that the DLP parts much better quality than the FDM parts. Additionally DLP provides smooth walls and can be use in the casting process. The best example is lost-wax method of casting, where the core of mold is printed of wax -like material and then burned-out without ash. The main product out of this technolgoy is jewelry.

DLP 3d printing process gives quality on 30 microns level and smoothness of walls unattainable for the FDM method.
