Modeling energy and resource use in additive manufacturing of automotive series parts with multi-jet fusion and selective laser sintering

摘要: Abstract With additive manufacturing (AM) becoming a competitive process for low to medium production volumes, rapid becomes an increasingly relevant approach. However, regulations and customers demand more eco-efficient life-cycles of products. This requires engineers designers pre-select between productive AM processes like selective laser sintering (SLS) multi-jet fusion (MJF), based on their expected environmental impact in series production. As SLS already debuted the mid-1980s, researches broadly explored parts’ mechanical properties, energy resource use. The (MJF) technology, introduced 2017, delivers comparable part properties at considerably higher print speeds. its use is still scarcely covered. To close this gap, publication develops model evaluation utilization case study with automotive exterior using EOS P396 HP 4200 MJF machine. Data from measurements material consumption as well job shows good predictability builds basis assessment. derived functional blocks allow estimation comparison sustainability different cases SLS. Despite similarities, results concerning greenhouse gas emissions cumulative are different. gained insights enhance pre-selection strategies, suitable printing technology during according aspects. Printer manufacturers users may find research insightful improvements comparability future processes.
