用于光固化3D打印设备的离型膜
摘要：
本发明公开了一种光固化3D打印设备的离型膜，所述离型膜本体为疏液材料制成，该离型膜本体内上开有通孔，所述通孔贯穿该离型膜本体的上下表面，并在离型膜本体的表面形成孔隙，该孔隙使得可光固化材料与离型膜本体的接触面上具有空隙，由于可光固化材料不浸润离型膜本体，当光或其他辐射能量照射在离型膜本体表面上的可光固化材料后，可光固化材料在离型膜本体表面固化形成固态的打印中间物，由于离型膜本体的表面上具有孔隙，使得打印中间物与离型膜本体的接触面上具有空隙，即打印中间物与离型膜本体表面的接触面积小，离型膜本体表面与打印中间物的附着力小，打印中间物能够与离型膜本体直接脱离，提高了3D打印的效率。
摘要（英）：

The invention discloses a release film used for a photo-curing 3D printing device. A release film body is made from a lyophobic material. Through holes are formed in the release film body and penetrate through the upper surface and the lower surface of the release film body, and pores are formed in the surfaces of the release film body and are also formed in the contact face of a photo-curable material and the release film body. Due to the fact that the photo-curable material does not infiltrate into the release film body, when light or other radiation energy is irradiated on the photo-curablematerial on the surface of the release film body, the photo-curable material is cured on the surface of the release film body to form a solid printing intermedium. Due to the fact that the pores areformed in the surfaces of the release film body, pores are also formed in the contact face of the printing intermedium and the release film body, namely, the contact area between the printing intermedium and the release film body is small, the adhesive force between the surface of the release film body and the printing intermedium is small, the printing intermedium can be directly separated from the release film body, and thus, the 3D printing efficiency is improved.
