Industrial 3D printing materials manufacturer6K Additive，一个部门6K， 和Fraunhofer激光技术研究所ILT宣布了一项合作，以创建一个完整的生命周期评估（LCA），以实施增材制造。
“There are conflicting views on additive manufacturing regarding its environmental impact compared to traditional manufacturing. The goal for this study is to analyze factual data to help us understand the real environmental impact of printing a metal AM part using LPBF,” said Dr. Jasmin Saewe, Head of the Department Laser Powder Bed Fusion at Fraunhofer ILT.
What aspects does the study highlight?
为了帮助理解材料通过添加剂制造过程和后处理的碳排放，该研究将采用可持续的生产Ni718 powder由6K添加剂生产，用于在激光粉末融合机上生产的工业组件。该研究的早期结果显示在Fraunhofer Ilt Stand＃51 Hall 11号Formnext 2022.
TheUniMelt platform该公司说，从6K提供了世界上任何其他物质生产平台无与伦比的多方面可持续性福利。以前，6K添加剂出版了两个life cycle assessment钛和镍粉的项目。远见管理一家独立公司进行了这项研究，该研究测量了与可打印金属粉末的生产相关的生态影响，尤其是将雾化技术方法与6K添加剂进行了比较。发现6K的UNIMELT工艺至少提供了91％的能量减少，而NI718粉末的传统工艺比传统工艺减少了92％。
“We are excited to partner with Jasmin and her team at Fraunhofer ILT for this research. Our previous study clearly highlighted the environmental advantages our UniMelt technology has over atomization, but this collaboration takes it to the next step shedding light on the entire AM process. The market has embraced sustainability and the results of this study will provide the tools to allow customers to identify real solutions and help organizations drive toward carbon neutrality,” said Frank Roberts, President of 6K Additive.
“我们还以为是极其重要的伊娃luate the entire process, including powder manufacturing, which is why we partnered with 6K Additive, which has a proven method of sustainable powder manufacturing,” added the Head of the Department Laser Powder Bed Fusion at Fraunhofer ILT.
添加剂制造中的生命周期评估
Previously, theSAM(Sector Skills Strategy in Additive Manufacturing) project released the initial findings of its3D printing survey，研究了增材制造教育在生态可持续性中的作用。由欧盟资助的项目由European Welding Federation（ewf），其中3D打印行业was reportedly a SAM Associated Partner, was creating a European Observatory in AM to classify and deliver the necessary skills for the technology. As part of this, the project was instrumental in combining the国际AM资格系统(IAMQS) and, consequently the survey results, proposed a competence unit to address the topic of sustainability in additive manufacturing.
此外，Additive Manufacturer Green Trade Association（AMGTA）宣布了一个研究项目的开始；一种life cycle assessment(LCA) that compared a 3D printed aerospace part to one that is conventionally manufactured. The LCA was carried out by the罗切斯特技术学院（RIT）Golisano Institute for Sustainability（GIS），将使用常规制造技术与3D打印的喷气发动机低压涡轮机（LPT）支架的摇篮与宽度环境影响进行了比较。
