Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for reducing adhesion during cure processing for a stereolithographic 3D printed object. The system includes resin tank for maintaining a liquid photopolymer resin. The system further includes a light source. The system further includes controller for selectively exposing the liquid photopolymer resin to form a solid object in the resin tank. The resin tank is constructed of a rigid material that has an oxygen permeability that is above a first threshold so as to reduce a separation force required to remove the solid object from the resin tank after curing.

Abstract translation: 方法，系统和装置包括编码在计算机可读存储介质上的计算机程序，包括用于在立体立体3D打印对象的固化处理期间减少粘附的系统。 该系统包括用于保持液体光聚合物树脂的树脂罐。 该系统还包括光源。 该系统还包括用于选择性地暴露液体光聚合物树脂以在树脂罐中形成固体物体的控制器。 树脂罐由具有高于第一阈值的氧气渗透性的刚性材料构成，以便减少固化后从树脂罐中除去固体物质所需的分离力。
