Optimization for structural applications of 3D steel printing
The wire-feed additive manufacturing technique is a more efficient technique for large-scale applications when compared to powder-bed additive manufacturing due to its high deposition rate. The advantages of metal additive manufacturing are already proven for small-scale objects, like the optimized node from Arup, which resulted in a reduction of mass and production complexity. However, the wire-feed technique is, except for the recent printed 3D printed bridge of MX3D, not applied for structural elements on a larger scale. From the properties of the wire-feed technique it is most efficient to print in a continuous process, creating thin shell structures. Thin shells are sensitive for imperfections and buckling and application of curvature can increase the capacity of thin shells. Therefore a form-finding is setup to maximize the failure load, including imperfections and buckling, while minimizing the mass for a plate and a thin cylindrical shell. Additionally, three plate s!
are printed at MX3D and tested at the TU/e to validate the calculation model. Finally, three case studies are performed for a wall element, a tubular column and a freeform column where the results of the shape optimization are compared with standard elements.
