Abstract
Laser additive manufacturing (LAM) enables the fabrication of customized components. In medical applications where components contain both dense and lattice material, the process has a significant influence on the design process impacting mechanical properties and manufacturing accuracy. Currently, both build rate and strut thickness of thin-walled lattices cannot be scaled leading to low build rates, inaccurately fabricated lattices, and high unit costs. Here, a method is presented to determine the melt pool geometry material independently. The proposed scaling laws can be utilized for scaling the build rate, precise fabrication of thin-walled lattice structures, and correlating process parameters with resulting component properties.
