ASTM International发布有关COVID期间添加剂制造的特刊杂志

Covid-19和添加剂制造是工业标准组织的新期刊的主题国际ASTM

智能和可持续的制造业于19日后制造时代’ comprises 21 peer-reviewed technical notes looking at how the COVID-19 pandemic has affected various areas of advanced manufacturing. Covered in the issue is the use of biotechnology platforms for vaccine production, the integration of artificial intelligence, the effect of additive manufacturing on supply chains, and more.

Explaining the reasoning for the issue, ASTM writes, “This pandemic created a totally uncharted territory, and nobody knows the path forward. Through this special issue, we want to give the world thought leadership for post–COVID-19 manufacturing. Though some of the use cases are from the USA, we feel that we have given the world a compendium of possible actions from practical and policy perspectives.”

添加剂制造作为紧急响应

Looking at the 3D printing content in the issue, the technical note ‘快速对混合制造的紧急响应进行快速改造’详细信息,在高生产需求时期,增材制造业以及常规生产过程如何作为紧急响应。

尽管现在少了,但在全球大流行的一开始,PPE单元,感染试剂盒和疫苗研究材料的数量却很短。为了满足整个人口的大规模需求,需要密集制造,并且这些产品的生产历史取决于工具和模具工业的平稳运行。

随着国际边界几乎在一夜之间关闭,从海外供应商进口的钢铁铸造出现了重大下降,尤其是由于削减了正常的供应链,美国尤其没有做好准备。ASTM已将混合制造系统确定为潜在的救星,因此3D打印可用于在本地制造铸件和其他工具,而减法制造可用于完成3D印刷零件并确保高表面质量。

此外,由于缺乏生产线,可以随时迭代复杂的工具几何形状,减少交货时间以及与长期产品开发相关的成本。对于某些“快速重新修复”的情况,该问题估计,增材制造可以将成本降低多达96%,同时减少一个国家对海外供应链的依赖,并使资金在当地经济中流通。

防寒工厂

The other major focus area takes a deeper dive into the supply chain, looking inside individual production facilities. ‘走向下一代大流行证明工厂探讨了3 d公关的作用inting in helping to create a safer working environment while protecting the productivity of an organization via production line redesigns.

随着社会距离的规则在世界上几乎每个国家都盛行,在商店地板上进行定期的日常操作变得极具挑战性。最重要的是,必须注意附近的同事,熟练的劳动者正在感受到由于封锁和隔离要求而导致员工短缺的影响。

该问题在这里将加性制造作为一种有用的工具,因为该技术的高数字性质使自己具有远程工作,从而在生产最少的物理人类存在的部位方面具有灵活性。现在,由于许多工业级机器正在吹捧物联网功能,因此可以通过一台计算机管理整个印刷农场。作为奖励,自动化后处理系统的兴起也是一个促成因素,可确保整个3D打印工作流程中的最小破坏。

As a standards developer, ASTM plays a part in every sector that makes use of additive manufacturing. The organization’sAdditive Manufacturing Center of Excellence(AM CoE) recently signed a cooperative agreement withNASA伙伴与“共同利益活动”合作。合作伙伴之间的三年合同,价值75万美元,将看到NASA确定潜在的3D打印项目for the AM CoE to execute.

早在9月,ASTM还启动了第三轮资金,以支持鼓励研究项目添加剂制造领域的标准化。The capital injection, supported by additional in-kind contributions, will go towards facilitating eight different projects with the ultimate aim of “aligning technical standardization with the rapidly evolving AM industry”.
