Reservoir assembly for enhancing a surface finish of a 3D-printed object

Abstract

The present invention concerns a system and reservoir assembly for three-dimensional (3D) printing. The reservoir assembly includes a top frame that may be filled with liquid material, and a tensioned film being held underneath the top frame. The tensioned film may be air permeable and flexible, wherein surfaces of the tensioned film may be micro textured. A bottom frame is coupled to the top frame and secures a transparent or semi-transparent rigid substrate. In exemplary embodiments, one or more filters may be positioned below the tensioned film. The one or more filters may employ a texture that is adapted to control blurring of a projected image during a printing process in order to enhance a surface finish of a 3D-printed object.
