Example of the lug showing internal lattice structure which has been added by RAM3D’s designer. www.engineeringnews.co.nz 19 Part design optimised for SLM and part functionality Often used where you have a part that is limited in its use by the manufacturing method. Usually the part cannot be created conventionally without a large compromise in design, (for example where you may have to make it in multiple parts due to manufacturing limitations, however, it would be better if it were made in one piece). Design for additive manufacture requires a very different outlook compared with design for subtractive manufacture. When using subtractive manufacture, often excess material is left on the part as it may be costly to remove resulting in an overdesigned part. Also, the method of material removal will often determine the part’s shape. (i.e., pocketing a machined part). That method of material removal can also compromise the part’s usability, strength, and function. Using an approach focussing on design for additive manufacture means that the part will only have material where it needs it and all applied loads are transferred in the most efficient way possible. The result will be a highly optimised part in both functionality and cost. RAM3D currently prints in the following materials: Inconel 718, Stainless Steel 15-5ph and Titanium 64.
