Abstract
Poly Phenylene Sulfide is a high performance plastics that is used in high-value parts. The
most commercially available plastic laser sintering machines employ Gaussian profile CO2 laser.
In this research, low temperature process of the material with tophat profile laser is tested. By
using tophat profile, a tensile strength of 64.5 MPa was obtained. The value is equivalent to 75%
of those from injection molding and 140% of standard laser sintered polyamide. Tophat profile
effectively suppressed sparkling and fuming and improved surface finish decreasing surplus
sintering or sticking powder.Mechanical Engineerin
