According to Uniformed Services University and NASA, “Using 3D biological printers to produce usable human organs has long been a dream of scientists and doctors around the globe. However, printing the tiny, complex structures found inside human organs, such as capillary structures, has proven difficult to accomplish in Earth’s gravity environment. To overcome this challenge, Techshot designed its BioFabrication Facility (BFF) to print organ-like tissues in microgravity, acting as a stepping stone in a long-term plan to manufacture whole human organs in space using refined biological 3D printing techniques.”
According to Sourabh Saha, the paper’s lead and corresponding author is now an assistant professor in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology, “Instead of using a single point of light, we project a million points simultaneously. This scales up the process dramatically because instead of working with a single point that has to be scanned to create the structure, we can use an entire plane of projected light. Instead of focusing on a single point, we have an entire focused plane that can be patterned into arbitrary structures.”
According to Relativity Space is a private American aerospace manufacturer company headquartered in Los Angeles, California, “Relativity Space was founded on the idea that Blue Origin and SpaceX were not doing enough to use 3D printing as part of rocket manufacturing. Relativity plans to 3D print an entire launch vehicle they call Terran 1. The extensive use of 3D printing has allowed the company to iterate designs quickly, use less tooling and human labor. In March 2018, Relativity Space signed a 20-year lease at the John C. Stennis Space Center, a NASA rocket testing facility, to test engine components and eventually test full-scale Aeon 1 rocket engines.
The company says it will launch its first rocket named Terran 1 from the site in 2020. Relativity plans to start commercial launch service by early 2021.”
WPI receives $25M ARL award for cold spray 3D printing process.
Damaged parts on military vehicles can lead to lengthy and costly service delays, but a novel cold spray 3D printing process developed at Worcester Polytechnic Institute promises to provide rapid repair and reduced downtime.
According to Danielle Cote, assistant professor of materials science and engineering and director of WPI’s Center for Materials Processing Data, “The Army is interested in cold spray 3D printing as a repair technique. Danielle Cote is the principal investigator for the ARL project. It’s cheaper to repair a part than to replace it, and you get the equipment back in service faster. The Army’s primary interest is unit readiness. If you’re on a mission and need to move quickly to a safer place, and a critical part on your vehicle breaks, you’re stuck unless you can repair it quickly. That’s where cold spray comes in.”
