Design for Additive Manufacturing of Cellular Structures

Abstract

Digital shape reconstruction is the process of creating digital models from physical parts represented by 3D point clouds. The ideal process is expected to provide a boundary representation that is likely to be identical or similar to the original design intent of the object, and requires minimal user assistance. This paper discusses alternative state-of-the-art approaches, where emphasis is put on automatic methods (i) to create complete and consistent topological structures over polygonal meshes; and (ii) extract accurate and properly aligned surface features that yield complete, trimmed CAD models with fillets and corner patches. Problems and recommended solutions will be presented through case studies using industrial parts.

Design and evaluation of additively manufactured parts with three dimensional continuous fibre reinforcement

“…By optimising design for function and reducing the buy-to-fly ratio it is possible to significantly reduce life cycle energy use and materials costs [9,10]. For similar reasons metals are being replaced with polymers and polymer matrix composites (PMCs).…”

Axisymmetric structural optimization design and void control for selective laser melting

“…This has been extended to a design methodology for designing truss structures for additive manufacturing, including an XML file format for the efficient exchange of these large degree of freedom truss structures (Chen 2006 andRosen 2007). This has also been used in controlling the morphing of a wing to favourably alter its cross-section during the duration of an aircraft's mission (Chu et al 2008). There are also applications of this technology to the medical industry.…”

Additive Manufacturing Technique for Corrosion less Bicycle Rim Production in Developing Countries like India

“…AM also supports the engineers to generate substances from personalized specific computer-aided designs, while employing automated processes and standardized materials as building blocks. A new method based on computer aided design for AM was proposed in [4]. The AM was used for biomedical applications [5].…”
