Description
Summary:Inexpensive metal 3D printing is having great physical value and the direct ink writing (DIW) method of fabricating metal parts is one of those techniques. This method is suitable for producing ceramic structures with near-net shapes at a very low cost. In this work, circular tricalcium phosphate (TCP) structures were printed by using the three-dimensional DIW technique. To prepare evenly distributed colloidal ink, PVA was selected as binder material for preparing 50 and 55 wt. % tri-calcium phosphate ink. The rheological property of the prepared ink was investigated to evaluate the extrusion process of the ink through a nozzle under pressure. The solid loading of 55 wt. % of TCP produced green body structures with good dimensional stability at a nozzle diameter of 1.2 mm, feed rate of 10 mm/s, and pressure of 1.5 bar and the average dimensional error of the sample was 3.08%.
