Apparatus, system, and method for use in three-dimensional printing

A system for three-dimensional printing, comprising:

• a computer coupled to a light source including instructions for selectively illuminating a photosensitive liquid in accordance with a geometric profile of a three-dimensional (3D) object, the light source for polymerizing the photosensitive liquid and forming a polymerized section of the 3D object;
• and
• reservoir assembly adapted to receive the light source, comprising:
• a top frame having a cavity with an aperture defined on a bottom edge of the top frame, the cavity configured to be at least partially filled with the photosensitive liquid;
• a permeable tensioned film stretchily coupled to the aperture so as to hold the photosensitive liquid within the cavity of the top frame;
• a bottom frame, removable from the top frame, including a transparent or semi-transparent rigid substrate, the bottom frame configured to register with the top frame;
• and
• a media layer disposed between the permeable tensioned film and the rigid substrate of the bottom frame, the media layer comprising a clearance between a top surface of the transparent or semi-transparent rigid substrate and a bottom surface of the permeable tensioned film.

A reservoir assembly for use in three-dimensional printing, comprising:

• a top frame having a cavity with an aperture defined on a bottom edge of the top frame, the cavity configured to be at least partially filled with a photosensitive liquid, wherein a deep portion of the cavity is defined by a peripheral shallow portion extending from an inner side wall of the top frame to a curving edge, and a deep inner side wall extending from the curving edge that perimetrically defines the aperture;
• a polymethylpentene (PMP) film wrapped around or adhered to a holding rim of the top frame so that the PMP film is tensionedly coupled to the aperture in a manner to hold the photosensitive liquid within the cavity of the top frame;
• a bottom frame, removable from the top frame, including a transparent or semi-transparent rigid substrate, the bottom frame configured to register with the top frame;
• and
• a media layer disposed between the permeable PMP film and the rigid substrate of the bottom frame, the media layer comprising a clearance between a top surface of the transparent or semi-transparent rigid substrate and a bottom surface of the permeable PMP film.
