Analysis of Lattice Unit Cells for Additive Manufacturing
Abstract
Additive manufacturing (AM), otherwise known as 3D printing, is an attractive manufacturing method due to its low cost, lightweight, rapid manufacturing characteristics. It is increasingly being used as an alternative to traditional machining, or subtractive manufacturing, methods with its ability to easily fabricate complex geometries. Additionally, AM offers unique weight reduction design opportunities due to its additive manner of fabrication such as latticing of parts. Latticed parts reduce weight through bulk material reduction while maintaining part strength. However, weight reduction is not the only use for latticing. This concept has gained increased interest for dielectric printing where by latticing a material the bulk material properties can be changed. This paper presents a study of different lattice structures and their unit cells, specifically how to design for a specific fill percentage.
