Abstract Scope |
Effective use of AM necessitates a comprehensive approach that considers design through final processing after the print. Each step has different cost drivers that can be used to optimize production costs through thoughtful design choices. For printing, two primary cost drivers are machine time and material cost. Designers often seek to reduce those through removal of unnecessary material, utilizing techniques such as topology optimization or lattice structures. However, lattice structures have inherent complexity that can impact print time and cost. This paper explores the impact of design choices on three types of lattice structures to be manufactured via laser-based powder bed fusion (LPBF) for a case study component. The type of lattice, unit cell size, and volume fraction of the lattice are observed to influence the print time of the final designs. The impacts of lattice structure design on print time and cost through build print time simulation are discussed. |
