ABSTRACT
Additive Manufacturing allows the creation of new structures; structures which were not thinkable before due to the manufacturing constraints. For structural steel this can save material and facilitate construction. However, when designing these structures some points need to be considered. The following article shows the different limitations when designing 3D-printed steel nodes using WAAM. As an example, a first node was designed, printed and tested. With the results of tensile tests, a realistic material model was developed to simulate the structural behavior of 3D-printed steel nodes. This was with good conformance experientially validated.
