Compared to traditional AM technology, properties like better vertical resolution, higher material filling rate, less production time, and less material waste make bottom-up AM technology a suitable candidate for fabrication of complex 3D materials with high accuracy. However during the pulling up stage, the substantial force generated between the formed part and the material container has high risk of breaking the part and therefore reduces the process reliability. The goal of this study is to reduce separation force between Fluorinated ethylene propylene (FEP) Film. IPG Fiber Laser was used to texturing pattern on the aluminium substrate. Afterwards contact angle goniometer was used to measure contact angle on that pattern. The time-histories of the pulling-up forces are measured using S-type load cells and to validate micro textured FEP Films effect on reducing separation force and probable application of this micro textured FEP films experiments were designed and conducted on Bottom-up Digital Light Processing (DLP) printer with 2 kind of resin vat (with micro Textured FEP Films and with original FEP Films) with same parameters.
