Development of a 3D model to predict curing dimensions and conversion rates of curable ceramic systems during stereolithography 3D printing process

To meet industry’s expectations for manufacturing ceramic parts by stereolithography, a better comprehension of the process, in particular laser scattering through slurry is mandatory. This knowledge makes it possible to define adapted printing conditions control dimensions, homogeneity conversion and mechanical properties green parts, order achieve resolutions optimize sintered parts. approach focused on development 3D polymerization modeling stereolithography process able predict curing associated thermal phenomena. First, design experiments carried out identify material-dependent parameters, calibrate validate model, then monomer rates dimensions after depending parameters. Finally, temperature variation exposure have been evaluated. These results will allow, future studies, interpret differences deformations
