提出了利用一种新型的高透气薄膜元件实现连续液面成型3D打印技术的方案并进行了实验验证。连续液面成型3D打印技术采用下入光结构，在光源与打印平台之间引入一个透明的透气薄膜元件，氧气可以通过薄膜元件渗透进入光固化成型表面，由于氧阻聚效应在光固化成型表面与透气薄膜之间产生一层液态未固化层。利用这一未固化层，3D打印平台可以连续不间断上移，实现了高速的连续光固化3D打印，纵向打印速度超过650 mm/h。由于连续液面成型3D打印技术较高的打印精度和效率，利用该技术进行建筑模型的制作，并将其应用于建筑模型的风洞测试研究。

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.
