Preliminary Investigation On Selective Laser Melting Of Pure Tin

Abstract

Selective Laser Melting is a 3D printing method that uses high power laser to melt selective regions of a powder bed and fabricate components layer-by-layer. It is capable of producing near full density components with metals. Tin is a low-cost metal with good corrosion resistance and a low melting temperature. However there has been no reported studies on SLM processing of tin. In this paper, a preliminary study on SLM of tin is carried out. The parameters were as such: scanning speed of 3,000 mm/s, layer thickness of 0.05 mm, laser power from 100 W to 200 W and hatch spacing from 0.1 mm to 0.2 mm. Relative density of 99.9 % was obtained.
