Correction of manufacturability based on the slice for ceramic vat photopolymerization

Ceramic vat photopolymerization (CVP) is a widely used Additive Manufacturing (AM) method for precision ceramic parts. In the pre-printing processing stage, to solve the manufacturability problems of overhang and thin parts in CVP, a generalized correction frame mainly based on non-contact support is proposed. While ensuring the printability of the model, this method does not change the design shape, and the contact support is minimized. Through experiments on three realworld cases, parts of the model with manufacturability issues such as thin parts and overhangs are successfully printed, which has important practical significance for the production of high-precision and complex ceramic parts.
