Robust design application for optimizing ABS fused filament fabrication process: A case study

Abstract

Abstract The current paper is a case study of optimizing fused filament fabrication (FFF) process using robust design. FFF process is a low cost 3d printing process that uses ABS (Acrylonitrile-Butadiene-Styrene) filament in order to build progressive layer by layer, physical prototypes. Four (4) parameters having three levels each ones is used (Deposition angle, Layer thickness, Infill ratio, Infill pattern). The quality indicator that used for the optimization process is the dimensional accuracy. It was found that the layer thickness is the most important parameter in the reported experimental area.
