摘要:
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. A permeable substrate is sandwiched between the tensioned film secured to the top frame and the transparent or semi-transparent rigid substrate secured to the bottom frame.
