3D Printing News Briefs
Raven Space Systems, a Kansas City startup, has been selected as one of the 14 companies to participate in the prestigious AWS Space Accelerator program. This program, powered by Amazon Web Services (AWS), aims to propel the growth and advancement of space-related startups. Raven Space Systems is at the forefront of innovation, leveraging 3D printing technology to revolutionize the space industry.
Raven Space Systems is tackling the challenge of on-demand cargo return from space with their groundbreaking automated factory and 3D-printed re-entry capsules. They have developed structures as strong as aluminum but with half the weight using aerospace-grade thermoset composite materials. Additionally, their heat shields offer higher performance compared to existing solutions.
With the support of AWS Space Accelerator, Raven Space Systems will receive training, mentorship, and up to $100,000 in AWS Promotional Credit. This opportunity will accelerate their growth and enable collaborations with AWS customers and partners in the space domain.
In collaboration with The Ohio State University and HX5 LLC, NASA has achieved a significant material science breakthrough by developing GRX-810, a 3D-Printed alloy with remarkable stress resistance, surpassing existing alloys by 600. As the demand for materials capable of enduring extreme conditions grows, previous research has shown that incorporating ceramic components into metal alloys enhances their resilience. However, the challenge lies in preventing the ceramic particles from floating to the surface during the alloy’s molten state. To overcome this obstacle, the research team employed a laser powder bed fusion 3D printing process, using nickel, cobalt, and chrome particles in ink combined with yttrium oxide powder. The ceramic particles were effectively infused throughout the alloy’s microstructure by printing alternating layers of metal alloy and powder particles and subjecting them to a laser heating approach known as oxide-dispersion strengthening.
