Abstract: Ceramic slurries may include ceramic particles, a photoreactive-photostable hybrid binder, and a photoinitiator. The photoreactive-photostable hybrid binder may include a photoreactive organic resin component, a photoreactive siloxane component, and one or more photostable siloxane components. Methods of forming a ceramic part may include curing a portion of a ceramic slurry by exposing the portion of the ceramic slurry to light to form a green ceramic part, and partially firing the green ceramic part to form a brown ceramic part. The brown ceramic part may be sintered at or above a sintering temperature of the ceramic particles to form a ceramic part, wherein sintering includes heating the brown ceramic part to a sufficient temperature to promote reaction bonding that converts silica from the photoreactive-photostable hybrid binder into silicates that bond with the ceramic particles.

Abstract: The present disclosure is directed to a method of altering chemical properties of an in-process resin used with a 3D printing apparatus. The method includes monitoring the in-process resin using an imaging spectrometer, comparing the in-process resin and a model using one or more spectrums from the imaging spectrometer, and diluting the in-process resin with a diluting resin.
