Abstract

The process parameters of selective laser sintering directly affect the mechanical properties and dimensional accuracy of the formed parts, and each forming material corresponds to a different combination of process parameters. For PA2200 material, the effects of laser power and scanning distance on the tensile strength and dimensional accuracy of the formed parts were studied. Through theoretical analysis and comprehensive experiments, the optimal parameter combination was obtained: laser power 40 W, scanning spacing 0.4 mm, tensile strength up to 46.42 MPa, X-direction dimensional accuracy deviation accounted for -0.25%, Y-direction dimensional accuracy deviation The proportion is -0.5%, and the Z-direction dimensional accuracy deviation accounts for 0.75%.
