添加剂制造商绿色贸易协会（AMGTA）是一个全球贸易集团，旨在促进和促进添加剂制造业的环境利益（AM），宣布发布其首个委托大学研究项目，这是基于文献的系统审查，对环境福利的系统审查金属的AM。该论文的标题为“关于金属添加剂制造的环境影响的知识状态”，由代尔夫特技术大学的Jeremy Faludi博士和达特茅斯学院的Corrie Van Sice撰写。
According to its authors, the report “synthesizes existing academic literature comparing the environmental impacts of metal AM with conventional manufacturing methods, and provides context with impacts of common metals and processing methods found in a materials database.” Its goal “is to summarize current knowledge and identify areas where information is sparse, unclear, and much needed.”
Key takeaways from the report include that, while “AM generally has much higher carbon footprints per kg of material processed than CM [conventional manufacturing] when considering the direct manufacturing process itself,” but “impacts depend greatly on part geometry—a solid cube will be much lower impact to produce by machining, while a hollow shell or lattice can be lower impact to produce by AM.” The report further recognizes the need for additional life cycle assessment (LCA) studies to quantify environmental impacts: “More LCA studies are necessary to definitively compare metal AM to CM; especially direct comparisons of AM to machining, and especially for technologies such as binder jetting and DED. These LCAs should ideally also include more of the product life cycle.”
“We were pleased to work with Dr. Faludi and Ms. Van Sice on this study,” said Sherry Handel, the Executive Director of the AMGTA. “No one should expect metal AM to be a more sustainable way to manufacture basic metal parts given the focused energy inherent in laser melting, but AM should present a more sustainable course for manufacturing finished precision components.” Ms. Handel continued, “These findings validate the AMGTA’s plans to provide the industry with rigorous, independent, and ongoing research. The AMGTA will continue to commission studies and publish research findings in an effort to update the industry and other key stakeholders on what our eco-footprint is now and what we will need to focus on in the future to be more sustainable.”
