Pioneering Space Manufacturing: AddUp and Airbus Send a Metal 3D Printer to the ISS

In a monumental step towards establishing autonomous manufacturing capabilities beyond Earth, French company AddUp, a renowned manufacturer of metal 3D printing solutions, has officially announced the successful delivery of a fully operational metal 3D printer to the European Space Agency (ESA). This groundbreaking achievement, developed in close collaboration with Airbus Defense & Space, signifies a critical milestone in humanity’s quest to explore and inhabit space. The customized metal additive manufacturing solution is specifically engineered to operate under the unique conditions of microgravity aboard the International Space Station (ISS), enabling the creation of intricate and functional metal parts in orbit. This ambitious project, initiated in 2016, addresses one of the most significant logistical challenges of long-duration space missions: the immediate availability of spare parts and tools.

The printer is slated for installation within the ISS’s Columbus scientific module, where it will embark on its inaugural mission to produce four distinct metal components. These parts will subsequently be returned to Earth for exhaustive analysis, allowing engineers and scientists to meticulously evaluate the structural integrity, material properties, and overall performance of objects manufactured in space. The ultimate objective is to validate the viability and reliability of metal additive manufacturing in a microgravity environment, paving the way for a future where astronauts can fabricate essential items on demand. This capability could dramatically reduce reliance on costly and infrequent resupply missions, enhance mission flexibility, and even support future lunar bases or Martian settlements by allowing for in-situ repair and construction. The ability to print metal components could extend mission durations, ensure crew safety by providing immediate access to critical spare parts, and foster truly self-sustaining space exploration endeavors, transforming our approach to venturing beyond our home planet.

Triastek’s FDA-Approved 3D Printed Gastric Device Revolutionizes Drug Delivery

In a groundbreaking development within the medical sector, Triastek has announced that its innovative 3D-printed gastric retention device, named T22, has received crucial clearance from the U.S. Food and Drug Administration (FDA). This landmark approval makes T22 the very first 3D-printed gastric retention device to achieve this prestigious certification, signaling a new era for advanced pharmaceutical delivery systems. The component was meticulously engineered using Triastek’s proprietary Melt Extrusion and Micro-Injection Molding (MED&MIM) process, a sophisticated additive manufacturing technique that allows for unparalleled control over drug release profiles and complex geometric designs, crucial for effective gastric retention.

This pioneering development holds immense promise for patients suffering from serious conditions such as pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). These conditions often necessitate strict and frequent dosing regimens, which can be challenging for patients to adhere to, impacting treatment efficacy and quality of life. T22 is designed to address this by significantly reducing the frequency of administration to a convenient once-daily dosage. By ensuring the medication remains in the stomach for an extended period, the device facilitates a controlled and sustained release of the active pharmaceutical ingredient. This not only simplifies the dosing regimen for patients but also substantially improves treatment compliance, leading to better therapeutic outcomes. The FDA clearance is a testament to the rigorous scientific validation and safety profile of Triastek’s technology, highlighting the increasing acceptance of 3D printing in producing highly specialized and effective medical devices and pharmaceuticals. Following this pivotal approval, Triastek is now preparing to initiate clinical studies with T22, aiming to further accelerate product development and bring this innovative solution to patients who stand to benefit most from its advanced drug delivery capabilities.

Scrona and Avantama Achieve Breakthroughs in Submicron 3D Printing for MicroLED Displays

A significant collaboration between Scrona, an ETH spin-off, and Avantama has yielded remarkable results in the realm of ultra-high precision additive manufacturing, enabling the realization of 3D printing at an unprecedented sub-micron scale. This technological leap is particularly impactful for the burgeoning sector of MicroLED displays, an area that demands extreme precision and novel manufacturing techniques. MicroLED technology offers substantial advantages over traditional displays, including superior brightness, enhanced energy efficiency, faster response times, and the potential for flexible form factors. However, their mass production has been hampered by the intricate challenges of placing millions of tiny LED chips with micron-level accuracy.

The synergistic partnership leverages Scrona’s groundbreaking electrohydrodynamic (EHD) inkjet technology, which distinguishes itself by its ability to process very high-viscosity inks – a capability far beyond that of conventional printheads. Unlike traditional inkjet systems where material drips from the nozzle, Scrona’s EHD technology precisely extracts the material from the nozzle using an electric field. This controlled extraction mechanism prevents undesirable spreading and allows for the deposition of materials with exceptional accuracy, achieving resolutions down to the micrometer and even sub-micron level. Complementing this, Avantama contributes its expertise in manufacturing high-performance quantum dot inks. These specialized inks boast very high absorption coefficients, making them ideally suited for integration into MicroLED displays where efficient light conversion is paramount. The combination of Scrona’s precise deposition system and Avantama’s advanced material science creates a powerful solution for manufacturing not only MicroLED displays but also opens new avenues for the production of advanced semiconductors, high-density microdisplays, and a wide array of miniaturized electronic components. This innovation promises to accelerate the development of next-generation devices that are smaller, more powerful, and more efficient.
