Abstract

3D printer is one of the techniques in Solid Freeform Fabrication (SFF) which is used to fabricate physical objects directly from CAD data sources and currently the raw material for the 3D printer is expensive and limited to a number of choices. This research introduces a new approach in developing powder material by using palm oil-based fly ash which is a by-product produced in palm oil mill as an alternative material for the 3D Printer whilst the main purpose is to reduce the cost in the development of a new product. Taguchi method, by using Qualitek-4 software as a tool of Design of Experiment was used to obtain the optimum process parameter which consists of layer thickness, ratio of mixing and binder setting saturation value (shell and core). Result from the experimentation work done shows that the alternative material can reduce up to 50% of the material cost with its dimensional accuracy, hardness and surface roughness at par compared to the ex~sting plaster based powder material.
