uV Curing Resins

uV curing resins have great promise as a medium in which clay can be 3D printed (in both SLA and FDM printers). Recent advances are claiming 80% or more solids loading.

Dental 3D printing has achieved the holy grail: uV hardening

Cutting-edge ceramic 3D printing is happening in dental! The focus is not primarily on the printers, attention is going into the paste. They are calling it "the resin" because acrylic resin is the likely medium. Pure alumina powder is being used (also pure silica). Imagine having a pure alumina tooth! What temperature does it take to fire these (and burn out the photopolymer network)? 1600C! They are achieving high percentages (likely 70%+) of the powder in an acrylic resin base and yet the slurry is very fluid (so it can be printed in a very narrow extrusion) and has minimal fired shrinkage. They are adding uV hardeners, this enables solidifying the material as soon as it leaves the printer nozzle. Data sheets specify exactly what uV wave length is needed. The key to the success of these efforts is meticulous lab work to perfect and adapt already established processes and materials. This material-centric lead could be adapted to so many other branches of ceramic fabrication and so many other materials could be made into resins. Another exciting area is investment casting. Thin ceramic shells are being printed and molten metal poured in to get shapes never before possible.
