Abstract Scope |
Applications for Ti-6Al-4V lattice structures produced through additive manufacturing are growing in defense and biomedical industries. Lattice structures can reduce weight and improve energy-absorption capacity in protection applications, or match properties with surrounding bone, and function as tissue scaffolds in biomedical applications. The degree to which 3D-printed lattice structure matches the original solid model depends on a number of factors, some of which include: type of additive manufacturing process utilized, orientation of lattice structure on build plate, type of lattice structure, and material utilized. Although some thresholds on dimension and orientation for 3D-printing of simple rod or plate can be found in literature, the large number of variables that influence lattice 3D-printing require thorough investigation. In this study, a wide range of strut-based and surface-based lattices were designed and fabricated in order to study defects and dimensional accuracy. Manufacturability limitations and mechanical properties for 3D-printed Ti-6Al-4V lattices will be presented. |
