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.

Abstract: A pressure sensing element has an elastic porous substrate, an electrode, an upper protective layer, and a lower protective layer. The elastic porous substrate is provided with a piezoelectric layer on a surface of the elastic porous substrate. The electrode is formed on at least one of a top and a bottom of the elastic porous substrate. The upper protective layer and a lower protective layer are provided respectively above and below the elastic porous substrate. The elastic porous substrate has multiple holes arranged in regular and repetitive patterns including gyroidal structures, lattice structures or schwarz structures.
