Selective Laser Melting offers design flexibility: complex products, usually built in numerous successive steps, can now be built in a single step and still have thin walls, deep cavities or hidden channels. An optimised design for SLM will limit the need support structures. The technique is mostly used in industries that benefit from weight reduction and where products are complex and produced in low quantities. Let's have a look at the topology optimisation process of a one-of structural node found in tensional integrity structures.
That’s what makes these structural nodes the perfect candidate for redesign and production with SLM . Why use 7 steps when you can manufacture it in 1? Topology optimisation for SLM process uses 2 successive steps: 1) Topology optimisation ; 2) Design optimisation for SLM.
re-design for SLM
All that is left to do is to combine FEA analysis with SLM-specific design optimisation in a single environment and make it available to AM engineers!
