The Application of Vat Polymerization Technique for Work Piece Fabrication

the measurement of the average surface roughness indicating the surface quality of a work piece. After a work piece was fabricated at a certain condition focused on different input factors (exposure time, bottom exposure time, bottom layer count, layer thickness, lifting speed, lifting distance, and retract speed), the average surface roughness was measured using a surface roughness tester. The measurements were done on the top side of a work piece. Three measurements were performed on three different spots to investigate the surface quality. The results indicate that the values of average surface roughness measured from the different spots fluctuate in a small range.
