Abstract

A novel method for subzero molding and imprinting includes the steps of shaping a photo-curable resin at subzero temperatures, triggering a photo or thermal initiator to set the photo-curable resin in its shape to produce a substrate, and de-binding and sintering the substrate. The novel system includes a pneumatic punch press, a male mold core and a female mold cavity, a male imprinting bit, a cold plate, and a resin vat containing a photo-curable resin. The inventive system and method produce objects with a cell wall thickness of 10-100 μm all the way to very large dense parts with no size limitations and at much higher speeds than any existing conventional technologies.
