Abstract
A fabrication apparatus and method for continuous printing all dimensions of a 3D object that includes a platform and a gas-permeable flexible film that has a carrier surface, wherein a printing area is defined between the platform and the film. A reservoir holding a photocurable resin is in the printing area. A pressure controlled air chamber is adjacent the reservoir and sealed by the film, the film dividing the reservoir and the pressure controlled air chamber. A light exposing device is configured to cure the printing area through the gas-permeable film to form the object from the photocurable resin. A fabrication apparatus and method for printing a 3D object that includes a linear actuator for moving the exposure device that operates with a control device to provide moving exposure images into a resin area larger than the size of a single image.
