Energy consumption model of Binder-jetting additive manufacturing processes

Abstract

Considering the potential for new product design possibilities and the reduction of environmental impacts, Additive Manufacturing (AM) processes are considered to possess significant advantages for automotive, aerospace and medical equipment industries. One of the commercial AM techniques is Binder-Jetting (BJ). This technique can be used to process a variety of materials

A framework to reduce product environmental impact through design optimization for additive manufacturing

“…Based on this correlation, the part fabrication orientation can be optimized. Xu et al (2014)proposes an energy consumption model for binder-jetting process. This model can be used to evaluate various materials with different process parameters.…”

Modelling of additive manufacturing processes: a review and classification

“…The power required for each sub-process is experimentally measured and a mean value is calculated. As a result, the approach of [123], for the calculation of the SLS AM process's energy consumption is a hybrid analytical-empirical one. For this KPI, which is directly connected to the build time, the analytical approach is, together with the empirical one, are ideal for its simulation.…”

“…In [119], empirical models of shrinkage rate, surface roughness are presented, whereas [120] and [121] deal with topology issues analytically and numerically respectively. In [122] an analytical energy consumption model has been developed, while a semi-analytical approach is presented in [123]. Studies using a numerical approach [113,121] model droplet kinematics and flow phenomena.…”

“…Type of binder, powder-bed characteristics [121] Topology, droplet kinematics Drag force, droplet deflection [122] Energy consumption [123] Energy consumption Part geometry and printing parameters studies on ME concentrate. In Table 9, a summarization of the process parameters and KPIs of the different modelling approaches can be seen.…”

Energy-aware manufacturing operations

“…In Xu et al (2014), the authors present a method to build an energy consumption model for the printing stage of a binder-jetting process in the promising context of additive manufacturing. For that purpose, they developed mathematical analyses to determine the correlation between the energy consumption and geometry of the manufactured part.…”
