China3D printingNet, January 1st, in a year dominated by the coronavirus pandemic, it seems difficult to surpass the outbreak, lockdown measures and serious consequences for the global economy. “Time” magazine even declared 2020 on the cover of its weekly issue on December 5 as “the worst year ever.” If anything, the global outbreak of COVID-19 and the containment measures adopted by governments will have serious consequences. However, in a turbulent year, the entire industry is looking for disruptive ways to regain momentum and participate in operations, and an industry rebounds faster than expected. Aerospace companies and startups have not only survived the pandemic, they have also witnessed some of the biggest space missions in several years.In addition, for the ever-expanding space3D printingMarket, which means more parts, machines and materials that use space technology for additive manufacturing. 2020 in China3D printingThe story of the space industry published online reveals one of the most innovative years of the past decade, which is consistent with plans for upcoming space exploration missions to the moon, Mars and other regions. By the end of 2020 and the beginning of 2021, we have selected ten stories, highlighting the most important developments in the industry in the future.
The first in-orbit ceramics made in space3D printing
Made In Space (MIS), a space-based manufacturing company, has now become part of the Redwire commercial space collection, and is the first company to successfully manufacture objects in an off-the-earth environment.After launching two to the International Space Station (ISS)3D printingAfter the machine, a commercial recycling machine and a ZBLAN optical fiber, MIS will send it to the first ceramic factory on the track on September 29, 2020. Only three months later, the first ceramic manufacturing plant was on track.The components are3D printingof. The Ceramic Manufacturing Module (CMM) demonstrates the feasibility of using pre-ceramic resin manufacturing in a stereolithography (SLA) environment. This is also an important milestone for manufacturing in the orbital microgravity environment. Due to the reduction of gravity-induced defects (such as deposition and composition gradients that occur in ground manufacturing), heat-resistant reinforced ceramic parts can have better performance.

NASA is3D printingRocket engine parts advance new AM technology
On September 11, 2020, we learned that NASA engineers are pioneering3D printingThe method of rocket parts, these parts can provide power for the moon landing and subsequent trip to Mars, which is part of NASA’s Artemis program.As part of the Space Agency’s “Rapid Analysis and Manufacturing Propulsion Technology” (RAMPT) project, AM experts are advancing the use of metal powder and laser3D printingTechnical development of rocket engine parts. This method is called the blown powder directed energy deposition method, which can reduce the cost and delivery time of producing large and complex engine components (such as nozzles and combustion chambers), and provide large-scale capabilities that AM previous development lacked. In addition, NASA’s Space Launch System program is investing in RAMPT’s blown powder directed energy deposition manufacturing process to certify it for aerospace. Together with RAMPT, the team is using this technology to build and evaluate tunnel cooling nozzles that are no more than 5 feet in diameter and nearly 7 feet in height. Directed energy deposition of blown powder can produce large structures, such as these engine nozzles, which are cheaper and faster than traditional manufacturing techniques.

Blue Origin3D printingBE-7 engine can land on the moon
After successfully completing Blue Origin’s fourth BE-7 engine test at NASA’s Marshall Space Flight Center on December 4, 2020, the company’s founder Jeff Bezos quickly announced on social media that his company’s3D printingThe engine will not only power Blue Origin and lead the National Team Human Landing System (HLS) lunar lander to support NASA’s Artemis program, but it will be the first to bring women to the moon. BE-7 is the latest high-performance engine in the Blue Origin series. High-performance, additive-manufactured liquid oxygen/hydrogen moon landing engine with a thrust of 10,000 pounds force (lbf)
