Photocuring printing system and method

A photocuring printing system, comprising a developing assembly, a carrier, a curing light source and a conveying mechanism configured to convey the material layer;

• wherein the conveying mechanism has a material layer attachment surface which is rotatable and light-transmissive;
• the conveying mechanism and the carrier are oppositely arranged and movable with respect to each other;
• the developing assembly comprises a developing drum, a developing engine and a feeder;
• the developing drum is rotatable around its central axis;
• the developing drum has a developing surface on which an electrostatic latent image is formed by the developing engine;
• the developing surface of the developing drum and the material layer attachment surface of the conveying mechanism are oppositely arranged;
• and
• during a rotation of the developing drum around its central axis, a photocurable material provided by the feeder is selectively attracted by the electrostatic latent image to form a material layer on the developing surface;
• the material layer between the developing surface of the developing drum and the material layer attachment surface of the conveying mechanism is attracted and attached to the material layer attachment surface of the conveying mechanism;
• the material layer is applied, by the conveying mechanism, on a forming surface of the carrier or a cured model on the carrier;
• and a curing light beam emitted by the curing light source passes through a material-laying side of the conveying mechanism to irradiate the material layer between the conveying mechanism and the carrier to form a cured layer.
