Laser Beam Melting (LBM), as an additive manufacturing technology, has high potential for efficient light weight production. Furthermore there is a huge capability of material saving compared to subtractive methods, which leads to cost saving and a positive ecological evaluation. Nevertheless for a successful process support structure is needed. The sort, amount, dimensions and placement of those structures are mostly based on the experience of the user. Usually there is one set of parameters for those structures applied to the whole part. Depending on how complex and filigree a part is, the amount of support structure could exceed the mass of the part itself.
To save material, built-up and post processing time while increasing the process stability, simulation based adaption of support structures can be used. In a build-up simulation, the distortion is analyzed and when exceeding a threshold, a new support is added or existing support is adapted and the simulation proceeds, taking the new support structure into account. First approaches with this method were made using pin-supports in dental applications.
