Most commercially available Selective Laser Melting (SLM) machines use galvano based laser scanner deflection systems. This paper describes the influence of the dynamical optimization of such galvano based laser scanner on the total scan time. The system identification of a galvano laser scanner was performed in combination with the development and implementation of an optimal 'Input Shaper'. Tests were performed on lattice structured SLM parts. The process time was hereby compared, with and without the use of the optimal 'Input Shaper'. Significant scan time reduction was observed when using the optimal 'Input Shaper'.
