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. A bottom frame is coupled to the top frame and secures a transparent or semi-transparent rigid substrate. A tempered glass 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. One or more spacers may be placed between the rigid substrate and the tempered glass substrate to form air gaps therebetween.
Apparatus And Method For Three-Dimensional Printing
The invention is generally a 3D printer configured for printing 3D objects using a high-viscosity photosensitive material. The 3D printer may include a fluid retaining assembly which comprises a rotating tank. A printing platform is situated in a manner such that a bottom surface of the printing platform makes contact with the printing solution in the tank. To facilitate printing using the high-viscosity printing material, a scraper assembly may be implemented in order to properly prepare the printing solution onto a surface of the tank. The scraper assembly prepares the material by scraping a layer of the material onto the surface of the tank for facilitating curing of the layer onto the printing platform.

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. 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.

Abstract:
The present invention concerns a reservoir assembly for use in three-dimensional (3D) printing for building a 3D object, which 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 elastic at the same time, wherein surfaces of the tensioned film are micro textured so that the tensioned film becomes optically clear when it contacts with the liquid material. The tensioned film minimizes the creation of bubbles between the top and bottom surfaces. This also helps blurring the boundaries thereby enhancing the surface finish of the fabricated parts.
