  • Patent number: 11964428
    Abstract: The present invention provides a bottom plate of a resin tank for three-dimensional printing, which is manufactured through the following steps: substrate surface roughening step: treating the upper surface of a transparent substrate by using a plasma, or disposing a composite film on the upper surface of the transparent substrate to form a non-smooth surface structure having pores; substrate surface modification step: sequentially performing an activation treatment and a fluorination treatment on the upper surface of the transparent substrate; and stabilizer filling step: applying a stabilizer to the upper surface of the transparent substrate to fill the stabilizer penetrates into the pores on the upper surface of the transparent substrate. The low surface energy film reduces the adhesion of the hardened photosensitive material, and the stabilizer maintains the structure of the low surface energy film, so that the resin tank bottom plate has both oleophobic and hydrophobic properties.
