Abstract Scope |
A unique binder jetting method is employed in printing 316L stainless steel components with the aim of improving both the green density of printed parts and subsequently sintered components. In this method, a water-soluble binder is premixed with 316L stainless steel powder before printing. During printing, water is jetted unto the powder/binder mixture to selectively activate the binder, layer by layer. The effects of printing parameters such as layer height, roller speed, shaking speed, powder/binder ratio and amount of jetted water (nozzle temperature) on the green density and sintered components are investigated. Results show that layer height and nozzle temperature affect the density and dimensional accuracy of the green compact. Results show that on reducing layer height, green density increases. However, the dimensional accuracy of the printed samples decreases, especially in the Z-direction. |
