Microstereolithography of ceramics

To create complex three-dimensional parts with novel properties (heat resistance, mechanical strength, conductivity, transparency, etc.), we can use stereolithography to shape light-sensitive resins heavily charged with powder of a specific material (ceramic, metal, etc.). The composites thus obtained then undergo two thermal treatments, debinding and sintering, designed to eliminate their polymer component by pyrolysis, and to ensure densification of the residual material.

Such a procedure has already led to the production of complex three-dimensional ceramic and metal objects, on SL machines adapted to the use of pasty materials and operating with a typical layer thickness of 100 µm
