Michigan-based additive manufacturing services providerQualified3D和德国添加剂制造服务提雷电竞充值供商METSHAPE有帮助的学生International Space Station（ISS）基于圣何塞的实验室Valley Christian High School通过微重力实验。
该团队需要微重力的毛细管动作试验。因此，他们联系了合格的3D，以获取使用微型图谱制造的组件。Valley Christian School的ISS计划经理Emeka Okekeocha表示：“我们的一些学生发现，使用LMM技术可以打印微型晶格设计，并主动与他们联系。”
“我们非常感谢合格的3D，因为他们总是如何迅速回答我们的要求和问题。即使我们要求进行许多更改，这些零件仍在按时交付，这帮助我们在计划和建立微重力实验之间顺利过渡。
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’s Lithography-based Metal Manufacturing（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。”
The ISS Research Lab students obtained their components within a couple of weeks and are excited to employ them in their microgravity experiment. The experiment package is expected to be delivered to the ISS in mid-February 2023 and to initiate returning data in March 2023.
此外,Metshape是全球known for its know-how in 3D printing and sintering LMM micro parts. It also retails its services to clients in the United States via Qualified3D.

Previously,加起来， 一种French industrial 3D printer manufacturer, announced that a novel machine it helped design would be launched into orbit for evaluation onboard the ISS. AddUp built the inner structure and mechanisms of a machine specially designed to 3D print metal parts in space as part of theEuropean Space Agency‘s (ESA) ‘Metal3D’ project. The prototype, unlike 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.
此外，瑞典3D生物生产商制造商Cellinkannounced a strategic partnership withMade In Space， 一种微重力制造specialist. 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.
