| Abstract Scope |
Laser powder-bed fusion is a leading technique for manufacturing intricate metal geometries, with lattice structures playing a key role. These structures reduce mass while maintaining mechanical strength by using small, thin cells. The overall mechanical behavior is closely linked to these individual features. Therefore, characterizing the mechanical behavior of small features becomes crucial for enhancing the overall mechanical strength. This study aims to address this challenge by fabricating thin struts of Ti64 using laser powder-bed fusion. Tensile coupons were fabricated at a 90-degree angle with a thin section at the center of the gauge. Circular and square geometries were fabricated with one, two, four, and nine pillars using five different process parameters. Tensile testing was conducted for each sample at least three times. The ultimate strengths were found to be consistent with those of laser-fabricated Ti64. However, premature failures were predominantly observed in multi-pillar samples with nine pillars. |
