Global standards developerASTM InternationalsAdditive Manufacturing Center of Excellence（AM COE）已将新成员添加到其材料数据和标准化（CMDS）计划的联盟中。材料是添加剂制造三杆的关键支柱，CMD的显着目标是“加速工业化和完全采用AM技雷电竞充值术”。
该财团与包括NASA,EOS,Boeing, andGE Additive。Sharedmaterial datasets and accelerated technology qualificationwere expected to serve as a rising tide that raises all ships.
新的CMDS成员包括认证的测试和资格合格公司ASTRO机械测试实验室, US-based metal part service providerDSH Technologies， 软件公司Dyndrite Corporation,制造技术部署小组（MTDG），工业机械制造公司PlastometrexandElnik Systems, engineering companySandvik, metal 3D printer manufacturerSLM Solutions, andSwiss Center for Electronics and Microtechnology（CSEM）。
CMD与其成员和监管机构一起，打算通过标准化工作来促进广泛采用AM技术。该计划将帮助建立和执行要求，同时开发“最佳实践”来创建强大的AM材料数据集并维护安全的仅成员数据管理系统。该计划还将旨在将经验教训和财团批准的材料数据转移到F42标准发展委员会中。参与该计划为成员提供了为各种活跃的工作流做出贡献的机会。CMD表示，这些工作流包括两个基于激光粉末融合（PBF-LB）和粘合剂喷射（BJT）的工艺工作流。此外，工作流将概述和执行为AM材料生成高质量数据的项目。
CMDS’ data workstream to improve efficiency in the AM industry
CMDS recently introduced its “Data” workstream that complements the Process workstreams by bringing together experts to develop solutions. These solutions help maximize the effectiveness of data workflows, from acquisition and management to analytics and learning. The work will result in data standards that will help recognize the total value of the digital thread throughout the AM value stream.
According to ASTM International, as the CMDS program grows, member recruitment expands beyond the early focus on defense and aerospace. Consequently, the program will gain members from the oil and gas, energy, medical, and transportation industries. Every year, the CMDS program works with its members and key agencies to select materials and application-specific properties like static, cyclic, and thermal properties. It will also launch multiple projects to support the development of standards.
Members will have exclusive access to all datasets to sustain their businesses. The knowledge acquired through these datasets will inform new standards and specifications, and maintain consistency in industry data. Additionally, Rick Huff, who serves as Additive Manufacturing Business Development Manager, will be promoted to Director of Industry Consortium and Partnerships as the consortium grows and expands.
Increasing the growth and development of new AM technologies through standardization
ASTM International is a global organization that sets technical standards through voluntary consensus for various industries and products. These standards help engineers design and manufacture products with confidence by knowing what parameters to use and what to expect in the manufacturing process. This leads to ensuring quality, consistency, and safety in the industry and the products that are manufactured making room for the growth and development of novel AM technologies. Similarly, global certification and risk management firmDNValso sets standards. Although both organizations focus on standardization, ASTM International primarily develops and publishes technical standards, while DNV provides risk management and certification services.
Last year, DNV released a new edition ofDNV-ST-B203 Additive manufacturing of metallic parts。According to DNV, the standard, which is the outcome of a joint industry project, includes baseline requirements for the most established AM technologies for metal parts and recognizes new quality assurance concepts for the upcoming era of data-driven manufacturing. DNV-ST-B203, in addition to the two technologies covered in the first edition, includes qualification and production requirements for three new AM technologies. The latest edition includes PBF-EB,PBF-LB, BJT，并使用电弧和激光束（DED-ARC和DED-LB）直接能量沉积。
活页夹喷气3D打印公司b-jetting启动了两台新的入门级打印机“教育家”和“研究人员”。Binder Jet system。B-Jetting Founders Dan Brunermer and James Gill developed the Educator platform to fill a market need for a simple, low-cost Binder Jet system. Decades of industry experience and client support back this system. This platform will debut in Chicago at theAdditive Manufacturing Users Group(AMUG) Conference.
Global industrial gas specialistLindeshowcased several gas technologies atFormnext 2022。这些技术包括林德的职业prietary gas mixture designed to optimize激光束粉床融合(PBF-LB), gas atomization solutions for metal powder production, and the increased use of special alloy nitinol (NiTi). Pierre Forêt, Associate Director, Additive Manufacturing at Linde, said, “Linde has long been a pioneer in developing innovative gas technologies to optimize manufacturing processes. In this rapidly developing world of Additive Manufacturing, we are delighted to showcase some of our most groundbreaking solutions at Formnext.”
