    In this paper, a technique to realize continuous liquid interface production 3D printing is presented by taking advantage of a new excellent gas permeable film, and is also demonstrated experimentally. The continuous liquid interface production 3D printer is constructed in a bottom-up schematic. A transparent and permeable film is introduced and placed between a light source and a 3D printing platform. In the process of printing, oxygen is injected into the printer and it permeates to the surface of photo-polymerizing layer through the permeable film. As a result of oxygen inhibition, an uncured liquid resin layer is generated between the permeable film and the lower surface of photo-polymerizing layer. Thanks to this uncured layer, the printing platform can be moved up continuously without interruption, achieving a high-speed continuous photo-polymerizing 3D printer with the maximum speed up to 650 mm/h in the longitudinal direction. Since the continuous liquid interface production 3D printer has various advantages such as high accuracy and efficiency, it is applied to fabricating architecture models for the experiments of wind tunnel test.
