Effect of Printing Parameters on the Surface Roughness and Dimensional Accuracy of Digital Light Processing Fabricated Parts
Source abstract
Abstract
The dental profession demands tremendous upgradation in terms of new materials for fostering innovation and promoting sustainable product design and manufacturing. To meet customer demand for elastomeric Rubber BLK 10 resin for clinical applications, researchers and industry leaders must continuously optimize its mechanical properties. The present study examined how layer height, build angle, and post-curing time affect surface roughness and dimensional accuracy of digital light processing resin 3D-printed specimens. Sixteen specimens were made according to the design of experiment runs to examine input factors. A Surfcom roughness tester and a Vernier caliper were used to examine the surface roughness and dimensional accuracy of specimens made using ASTM standards. Minimum surface roughness of 0.242 microns and maximum dimensional accuracy of 97.27% are achieved with 50 microns layer height, build angle of 45°, and post-processing time of 60 min. Further, MOGA-ANN is used to optimize the output responses and minimum surface roughness of 0.241 microns, and a maximum dimensional accuracy of 97.84% is achieved with 20 microns layer height, build angle of 85°, and 60-min post-processing time, and same has been validated experimentally.
