A type of Vat Photopolymerization using a hollow, air-filled tube that is open at the bottom as the printing interface. A glass window seals the top of the tube. The tube is immersed into the photopolymer vat, and an air-liquid meniscus forms at the open end of the tube. A light pattern is projected through the glass top, along the tube, and focused on the air-liquid interface. The pressure in the tube can be modified to adjust the position and curvature of the meniscus to make the interface co-planar with the focal plane. The tube is raised continuously to create the resulting solid part.
Abbreviated as DIP.
