5 CONCLUSION AND OUTLOOK
In this contribution a heat input reduction approach for
SLM processing was introduced. Three different heat
input models based on real process parameters were
developed and evaluated. The final, most reduced,
modeling strategy was applied on real 3-D twin can-
tilever geometry. The computed deformed shape and
residual stress distribution of the twin cantilever beam
proves to be similar to other relevant experimental
investigation of the literature (Zaeh & Branner 2010).
Future work is currently planned which includes
