Why this company matters

AMPulse analysis, not a company disclosure

Raven Space Systems has developed Microwave Assisted Deposition (MAD), a 3D printing process that cures thermoset composites in situ using microwave energy. This approach addresses a longstanding bottleneck in composite additive manufacturing: the need for post-print autoclave or oven curing, which adds labor, waste, and cycle time. By curing as material is deposited, MAD aims to accelerate production of high-strength, lightweight components for critical aerospace and defense use cases.

The company's core technology works with off-the-shelf aerospace-grade thermoset and ceramic materials. Products include optimally designed structures, thermal protection systems, and hypersonic testbeds branded as Mach3D. Raven holds a granted patent covering systems and methods for microwave-assisted deposition in 3D printing, with additional patent-pending applications related to the MAD process.

Raven's target customers are primes and agencies in aerospace, space, and defense. The company has secured research agreements with NASA and the Air Force Research Laboratory, as well as a $1.8 million Phase II STTR contract from AFWERX. Partnerships include AFWERX, the National Science Foundation, the University of Illinois Urbana-Champaign's CHESS facility, and SpaceWorks Enterprises. Raven plans to open an aerospace-certified production facility by Q2 2025 and has a planned demonstration mission for a 3D printed space capsule to the International Space Station.

The company's competitive differentiation lies in its exclusive focus on scalable, in-situ microwave curing for thermoset composites, a niche not addressed by traditional manufacturing or by thermoplastic-focused additive processes. Competitors such as Stratasys, Lockheed Martin, and Boeing offer broader composite manufacturing capabilities but do not specialize in this curing method. Raven's key risk is scaling from research-stage agreements to production-scale contracts with aerospace primes, a transition that requires certification and capital. The company has raised $7 million from Backswing Ventures, 46 Venture Capital, Mana Ventures, What If Ventures, and Cape Fear Ventures.
