国际标准组织( ISO)和美国材料试验协会(ASTM)共同制定了国际添加剂制造标准发展结构,随着添加剂制造领域快速发展,这一标准将更好地满足新技术标准的需求。添加剂制造(AM),又称3D打印,该工艺将材料一层一层地叠加,与传统的“减法式制造”方法如机器制造截然不同。
这一新标准框架将有助于:
•指导AM标准化过程中全球专家和标准制定组织的工作;
•确定AM行业中标准相关的差距和需求;
•防止AM标准开发中出现重复工作;
•确保AM标准之间的衔接良好;
•优先考虑AM标准领域;
•提高AM集团中制造商、企业家、消费者和其他相关人员的可用性和接受度。
基于本标准框架,行业标准可从三个层次发展完善:
•一般标准(如概念、通用要求、指导和安全);
•广泛类别的材料(如金属粉末)或工艺(如粉末床熔合);
•特定材料(如铝合金粉末)、工艺(如与ABS填充材料)或应用材料(如航空航天、医疗、汽车)的专门标准。
MET-L-FLO公司总裁兼ASTM添加剂制造技术(F42)国际委员会主席Carl Dekker表示:“这一标准将促使世界各地的行业专家更方便高效地交流,从而加速实现新技术集成和应用。未来,这一标准将带来更多好处,如实现人力资源统一培训,更加关注产品质量的持续改进,而非过分关注产品规格的潜在误解。
7月份在东京举行的会议上,这一标准框架通过了F42和ISO / TC 261标准。这表明,五年前两个全球权威标准制定组织之间签署的《合作伙伴标准制定组织》协议取得了进展。在创建本标准文档时,两个组织分别审查了标准的过去和现状,以及标准的计划开发工作。
新标准框架不限制任何标准组织的工作范围,仅提供可满足大多数标准需求的框架。目前正在制定一个平行指导文件,配合这一标准框架发行。
该框架是合作伙伴标准制定组织(PSDO)合作协议的一部分,这一协议于2011年由ISO和ASTM的理事机构与ISO成员机构(ASTM在其中拥有法定席位(ANSI))协商批准通过。
ISO and ASTM International unveil framework for creating global additive manufacturing standards
ISO and ASTM International have jointly crafted the Additive Manufacturing Standards Development Structure, a framework which will help meet the needs for new technical standards in this fast-growing field. Additive manufacturing (AM), also known as 3D printing, is the process of joining materials layer upon layer, as opposed to "subtractive manufacturing" methods such as machining.
The new structure will help:
- guide the work of global experts and standards development organizations involved in AM standardization;
- identify standards-related gaps and needs in the AM industry;
- prevent overlap and duplicative efforts in AM standards development;
- ensure cohesion among AM standards;
- prioritize AM standards areas; and,
- improve usability and acceptance among the AM community, including manufacturers, entrepreneurs, consumers, and others.
Based on this structure, standards can be developed at three levels:
- general standards (e.gs., concepts, common requirements, guides, safety);
- standards for broad categories of materials (e.g. metal powders) or processes (e.g. powder bed fusion); and,
- specialized standards for a specific material (e.g. aluminum alloy powders), process (e.g. material extrusion with ABS), or application (e.gs, aerospace, medical, automotive).
“This structure will help experts worldwide interact in a more streamlined and meaningful way, leading to the integration and application of new technologies at an accelerated rate,” said Carl Dekker, president of MET-L-FLO Inc., and chair of ASTM International’s committee on additive manufacturing technologies (F42). “In the future, we could see even more benefits, such as uniform workforce training and a stronger ability to focus on constant quality improvement rather than potential confusion surrounding specifications.”
This structure was jointly approved by F42 and ISO/TC 261 after a July meeting in Tokyo. This reflects progress under the Partner Standards Developing Organization agreement signed five years ago between the two globally-respected standards development organizations. In creating this document, both groups reviewed past, existing, and planned standards development efforts.
The new structure does not confine the scope of work for any standards organization but provides a framework in which the majority of standards needs can be met. A companion guidance document is also being developed to accompany this structure.
This framework is part of the Partner Standards Development Organization (PSDO) cooperation agreement that was approved in 2011 by the respective governing bodies of ISO and ASTM in consultation with the ISO national member body where ASTM has its legal seat (ANSI).
