he present invention introduces a novel submicron-structured PDMS film laminated on an LCD panel (mentioned as non sticky display (NSD)) for LCD-based 3D printing. It is specifically designed to overcome two critical challenges in the field: surface roughness and interface sticking. The core innovation lies in the precisely engineered randomly oriented submicron surface structure like a lotus leaf with an average roughness (Sa) of 0.27 μm and root-mean-square roughness (Sq) of 0.36 μm for NSD 2000. It enables controlled light diffusion while maintaining high optical transmission of 85.4% at 405 nm wavelength. This unique surface architecture creates a stable hydrophobic barrier through trapped air pockets, demonstrated by a contact angle of 120.1°, while simultaneously functioning as an electrostatic barrier between the LCD panel's glass cover and the Teflon interface. The technology's effectiveness is evidenced by an 82.5% reduction in surface roughness of printed parts and significant decreases in separation forces such as 28.4% for high-viscosity foam resins and 8-fold for fast-curing resins.
