Abstract
Solid freeform fabrication (SFF) is one of the techniques in direct metal parts fabrication in manufacturing technology. Currently there are limited in the choice of metal powder based materials in rapid prototyping. The most common used materials for bone replacement are stainless steel, cobalt-chromium alloys and nickel titanium. This paper discussed on the development of titanium-based mixture which is suitable for freeform fabrication by inkjet 3D printer. This research is aimed to formulate the suitable titanium-based powder using in mini inkjet printer. The specimen will heated in the furnace about 80% from the melting point temperature of titanium. Based on result obtained, it found that binder content in the composition should be lower than 20% for successful fabrication of titanium samples by 3DP technique. This is reported that the sintering process was increase 20% of the surface roughness and 40% of hardness value of the samples. The influences of adhesive binder content on the physical and mechanical properties of the fabricated parts, before and after sintering process has been obtained in order to achieve best quality of parts.
