Abstract: (3738 Views)
Nowadays, laser3D printers are one of the best and efficient devices for rapid prototyping techniques. There is vast number of studies about quality of samples in these printers. In this study, wehave tried to consider the role of laser scanning pattern in tensile strength as an important quality factor of the samples which are sintered by laser in single layer procedure. Experimental samples have been sintered with low power CO2 laser on Polypropylene powder with 200 micrometer grain size. Tensile strength and dimensional deviation of samples have been tested according to ASTM D882 standard and results are reported eventually.
