Michigan-based additive manufacturing services providerQualified3D和德国的加法制造服务提雷电竞充值供商METSHAPE有帮助的学生International Space Station(ISS) Lab at San Jose-based山谷基督教高中with a microgravity experiment.
The team required millimeter-scale lattices for capillary action trials in microgravity. Consequently, they contacted Qualified3D to obtain components manufactured using micro-stereolithography. Emeka Okekeocha, ISS Program Manager at Valley Christian School said, “Some of our students discovered that the miniature lattice design was printable using the LMM technology and proactively reached out to them.”
“We are very thankful to Qualified3D for how they always quickly responded to our requests and questions. Even with the many changes we requested, the parts were still delivered on time, which helped us to transition smoothly between planning and building our microgravity experiment,” said David Kou, an 11th-grade member of the team at Valley Christian School.
How were the students able to find the solution for this microgravity experiment?
总部位于圣何塞的团队的晶格由直径为0.5mm的撑杆组成，Micro-SLA似乎是唯一能够生产具有足够精度零件的过程。尽管尺寸精确，但光聚合物树脂成分并不适合太空飞行需求，因为它们缺乏抗振动性，热量和低温。金属为ISS实验提供了一组出色的特征。但是，晶格设计无法使用标准的金属粉末床融合和固定固定的3D打印技术可打印。
As a result, the group decided to useMETSHAPE的基于光刻的金属制造（LMM）是一种采用光聚合原理的新型3D打印技术，其中金属粉末分布在光敏的树脂中，并通过DLP投影仪仔细聚合。在包括钛和不锈钢在内的各种金属中，该技术可以创建具有光滑表面（抛光前2-5µm的表面粗糙度）和超薄壁（125µm）的组件。Okekeocha进一步指出，经过技术审查，我们接受了从丙烯酸酯树脂到不锈钢的拟议更改。”
ISS研究实验室的学生在几周内获得了他们的组件，并很高兴将它们雇用在其微重力实验中。预计该实验包将于2023年2月中旬交付给国际空间站，并在2023年3月启动返回数据。
此外，METSHAPE以其3D打印和烧结LMM微部件的专业知识而闻名。它还通过合格的3D向美国客户零售。

Previously,加起来法国工业3D打印机制造商宣布，它有助于设计的新型机器将被启动到轨道上，以便在ISS上进行评估。添加构建了专门设计用于空间中3D印刷金属零件的机器的内部结构和机制，作为该机构的一部分European Space Agency(ESA)的“Metal3D”项目。原型,不像traditional powder bed-based systems, is claimed to process wire feedstock attached to its frame, preventing it from floating away and enabling the device to operate inmicrogravity conditions。
Furthermore, Swedish 3D bioprinter manufacturerCELLINKannounced a strategic partnership withMade In Space, amicrogravity manufacturingspecialist. The collaboration’s objective was to determine 3D bioprinting development opportunities for the ISS and future off-world platforms. Such initiatives are expected to have a real-world impact on drug screening and cancer research on Earth, claims the company.
“CELLINK supports space programs in the United States with our deep commitment to cutting-edge innovation, extensive portfolio of technologies, and a world-class team of scientists and engineers,” said Erik Gatenholm, co-founder and CEO of CELLINK.
