Abstract

The assessment and minimization of energy consumptions of additive manufacturing (AM) processes are currently emerging research tasks. It is evident that the energy consumption of an AM process can be one or two orders of magnitude higher than conventional manufacturing processes. For improving the sustainability performance of AM, the energy use of AM should be evaluated and optimized in the design phase for planning products and AM processes. In order to support the quantification and evaluation of the energy consumption of AM, we have developed an energy simulation of a desktop AM system by using a physical modeling approach. Moreover, experiments have been carried out to validate and confirm the simulation accuracy and reliability. The result of the experimental validation has shown that the accuracy of the developed simulation approach can be up to approximately 98 %.
