Effect of design and tensile testing specimen geometry on final tensile properties of powder bed fusion plastic

In Laser Powder Bed Fusion there are certain considerations that need to be accounted for when designing thin-walled or complex shapes. Much is known of how parameters such as build orientation and scanning strategy can affect the resultant tensile properties. The property results also influenced by factors shape specimen. specimens’ cross-sectional geometry length ratio carefully considered obtain accurate reliable Eighteen different geometries were manufactured using an EOS P110 PA12 powder. These chosen evaluate influencing width, gauge length, specimen strategy. This knowledge used in conventional standards determining geometries. work aims combine L-PBF best represent actual properties polymer
