Abstract
A ceramic resin is provided, along with its methods of formation and use. The ceramic resin may include a crosslinkable precursor, a photoinitiator, ceramic particles, and pore forming particles. The ceramic resin may be utilized to form a ceramic casting element, such as via a method that includes forming a layer of the ceramic resin; applying light onto the ceramic resin such that the photoinitiator initiates polymerization of the crosslinkable precursor to form a crosslinked polymeric matrix setting the ceramic particles and the pore forming particles; and thereafter, heating the crosslinked polymeric matrix to a first temperature to burn out the pore forming particles.

A ceramic resin, comprising:
- a crosslinkable precursor;
- a photoinitiator;
- ceramic particles, wherein the ceramic particles comprise 50% to 90% by volume of the ceramic resin;
- and
- pore forming particles, wherein the photoinitiator is a UV photoinitiator that is configured to initiate polymerization of the crosslinkable precursor upon exposure to UV light at a temperature below 50° C. to form a crosslinked polymeric matrix setting the ceramic particles and the pore forming particles.
