Resin for production of porous ceramic stereolithography and methods of its use

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.

A method of forming a ceramic casting element, the method comprising:

• forming a layer of a ceramic resin, wherein the ceramic resin comprises a crosslinkable precursor, a photoinitiator, ceramic particles, and pore forming particles, wherein the ceramic particles comprise 50% to 90% by volume of the ceramic resin, and 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;
• 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.
