A Study on the Influence of FDM Parameters on the Compressive Behavior of ASA Parts

Abstract

The article presents the results of the study on the influence of FDM 3D printing parameters on the compressive behavior of test specimens made of ASA. In this context, 45 ASA test specimens, made by FDM on the Anycubic 4 Max Pro 2.0 printer, with height of the layer applied in one pass Lh equal to 0.10, 0.15, and 0.20 mm and filling percentage Id equal to 50, 75, and 100%, were compressive tested on a Barrus White 20 kN universal testing machine. The two considered variable parameters influence the compression resistance of the ASA parts, with the influence of Id being greater by 96.89% compared to the influence of Lh. It was measured that by increasing the filling percentage from 50% to 75%, the compressive strength increases by 38.10 – 39.31%, and by increasing the filling percentage from 75% to 100%, the compressive strength increases by 27.74 – 30.82%.
