Additive Layer Manufacturing (ALM) also known as 3D Printing is the forthcoming advanced manufacturing technique. An overview of ALM techniques with several examples and videos will be presented. The enormous potential of light weight designs and the barriers of commercialization will be discussed. Although CAE and Topology Optimization are mature technologies are not tailored yet to ALM. The set of CAD and CAE enhancements to unlock the ALM potential will be presented.
