Abstract

The 3D printing process has been implemented in rapid tooling processes including manufacturing the casting pattern. The pattern must have a surface roughness value as small as possible to reduce the costs of the finishing process. In addition, the printing time must be as short as possible to reduce the production cost. Therefore, the parameters of 3D printing that influence surface roughness and printing time need to be investigated and optimized. The investigated parameters are layer thickness, printing speed, and extrusion temperature. The Taguchi-Gray Relational Analysis using an orthogonal array L9 is implemented as the optimization method in this research. The optimal parameter combination that results in the lowest surface roughness and printing time is obtained at an extruder temperature of 240°C, a printing speed of 20 mm/s, and a layer thickness of 0.06 mm. The printing speed contributes 73,3% of the total parameter contribution and the layer thickness contributed 18 %. Meanwhile, the extruder temperature contributed the least to both responses.
