[15A-T7-01] Optimisation of Stainless Steel 316 Powder and Printing Parameters to Enhance the Densification in Binder Jet 3D printing (BJT) Additive Manufacturing Process
Keywords:BJT, SS 316, Powder
The objective of this experimental investigation is to identify the effect of powder characteristics and printing parameters on the green density and sintered material properties of BJT parts in SS 316 material. The study conducted has evaluated the powders with Indo-MIM engineered PSD (D100: -60 microns), Standard AM PSD (D100: -25 microns) with varying particle size distributions with varied roller traverse speed. The INDO-MIM powder shows a significant increase in flowability. The results show that by optimizing the particle size distribution increases the green density and helps to increase the layer thickness up to 80µm. But In Indo-MIM engineered powder roller speed increased double compared to regular AM powder with good printability and without defects. The INDO-MIM engineered powder sintering shrinkage can be reduced 10-11 % with ~ 99% sintered density, better mechanical properties .
