Selective Laser Sintering is one of the rapid prototyping process, can be defined as a
group of techniques which is used to quickly fabricate a scale model of a part or assembly using
three dimensional computer aided design (CAD) data. In this present work important process
parameters of the SLS process such as layer thickness and orientation of part is taken as input
parameter. In this present work important process parameters of the SLS process such as layer
thickness and orientation of part is taken as input parameter. Specimens are prepared for Tensile
testing as per ASTM standards. Their influence on responses such as Tensile strength and Yield
point strength is found.
After results and analysis, it is concluded that layer thickness is more significant parameter for SLS
process than orientation. If we increase layer thickness and orientation mechanical property like
tensile strength and yield point strength decreases. So for better result of fabricated part layer
thickness and orientation should be lesser as SLS is layer wise manufacturing process.
