Evaluation of Surface Roughness of Two 3D Printed Resin Material

Abstract

Purpose: this in vitro study evaluates the surface roughness of two commercially available 3D-printed resin subjected to different surface treatments. Methods:  a total of 36 specimens (saremco and senertek , n=18) was distribute into two groups, each group then subdivided into three group (control, polished and polished with glaze, n=6 per group). Surface roughness (Ra) was measured using Atomic Force Microscopy (AFM). Results: AFM shows a significant difference within the group and between two groups of 3D printed resin. Conclusion: overall surface roughness was less in saremco compare with senertek, on the other hand surface roughness was less in polished and glazed then in polished only and both of them is within acceptable value of roughness for saremco but in senertek only polished and glazed was within acceptable value.
