Application of photo cured 3D printing technology in carving
The photo cured 3D printing technology and digital carving modeling software are introduced as well as the preparation of photosensitive resins.The photosensitive resin prepared by adding toughening agents and initiators to silicon modified polyurethane acrylate oligomers has low viscosity,which can be used by photo cured 3D printing to obtain products with high toughness and molding accuracy.The slurry of photosensitive resin and stainless steel powder obtained by adding reactive diluents,photoinitiators,dispersants,and stainless steel powder to poly(ε-caprolactone)diol diacrylate can effectively achieve rapid prototyping of metal powder after photocuring printing through stereolithography technology.A mixed solution of ceramic precursors is obtained by mixing vinyl polysilazane with reactive diluents and adding photoinitiators and free radical scavengers,which can be photo cured to obtain photosensitive resin ceramics with good interlayer bonding and molding effect.
