Tethers Unlimited to Develop 3D Printed Spacecraft With Embedded Radiation Shielding

Comments

Tethers_Unlimited_LogoBothell, WA, 19 September 2013 (TUI PR) – Tethers Unlimited, Inc. (TUI) has signed a contract with the Air Force Research Laboratory (AFRL) to develop technologies to enable 3D printing of spacecraft structures with embedded radiation shielding. Under this Phase II Small Business Innovation Research (SBIR) contract, TUI will develop its patent pending processes for creating structural elements containing an internal layered composition of polymers and metals that is exceptionally efficient at absorbing space radiation. This “Versatile Structural Radiation Shielding” (VSRS) technology takes advantage of the flexibility of 3D printing to enable rapid and affordable fabrication of customized parts that minimize the mass required to shield spacecraft electronics.

“The desire to lower the cost and improve the performance of spacecraft systems is driving many satellite developers to consider commercial, off the shelf, or ‘COTS’ electronics, but these components are more susceptible to radiation than the very expensive hardened components that are traditionally used,” said Nestor Voronka, TUI’s Chief Technologist. “The VSRS technology integrates radiation shielding into the spacecraft structures so we can enable those COTS components to operate reliably while maintaining their low cost and low mass advantages.”

“The VSRS project builds upon our extensive work over the past five years adapting additive manufacturing techniques to fabricate multifunctional spacecraft structures,” said TUI’s CEO and Chief Scientist, Dr. Rob Hoyt. TUI has used these processes to create spacecraft exoskeletons with integral multi-layer thermal insulation, and under funding from NASA’s Innovative Advanced Concepts program it is currently developing ways to fabricate spacecraft structures on orbit. “We hope to leverage the power of additive manufacturing to enable a radical change in the way spacecraft are built, dramatically reducing costs and increasing performance for many missions.”

    Radiation have its good and bad effects . It used in many areas like medicals , space , printing and more on . This team working very good on radiation and doing great innovation . Tethers Unlimited done such nice work . Thank you for these all .
