After securing a Phase 2 contract with the U.S. Air Force within months of creating their product, Raven Space Systems co-founders Blake Herren and Ryan Cowdrey realized they had a groundbreaking concept: 3D printed reentry capsules for on-demand space cargo return.
“It’s a breakthrough in composite 3D printing,” said Herren.
Elevator pitch: Raven Space Systems is developing 3D printed hypersonic flight testbed vehicles for the defense and space industries to accelerate the development of hypersonic materials and technologies.
- Founders: Blake Herren, Ryan Cowdrey
- Headquarters: Kansas City
- Founding year: 2020
- Current employee count: 2 full-time, 1 part-time
- Funding to date: $1.5 million
- Noteworthy funders: NASA, National Science Foundation (NSF), U.S. Air Force
- Noteworthy programs: AWS Space Accelerator, Creative Destruction Lab (CDL) Space Stream
The duo had a busy 2023, deeping impact for their startup while participating in the AWS Space Accelerator and earning a winning spot among LaunchKC grants competition finalists.
“(LaunchKC is) going to help us a lot with the $50,000 and free office space in KCMO. We’re excited to move to a place we found in the West Bottoms,” said Herren.
Raven Space Systems’ work within the AWS space accelerator earlier this year proved beneficial, he said, emphasizing the program gave the company a boost by establishing valuable connections.
“That was a good kickstart from where we were,” said Herren. “We were super early in our concept, and that helped us start building a network in the space industry more than anything.”
The pandemic provided the duo time to brainstorm. In just a few months collaborating in Cowdrey’s garage during their graduate studies at the University of Oklahoma in 2021, they stumbled upon their groundbreaking invention.
“We shifted from building a 3D printer as a research tool and entirely focused on MAD3D (microwave-assisted-deposition) printing. We just saw that there was massive potential there,” said Herren.
After receiving funding from NASA to print reentry capsule heat shields using MAD3D printing, they knew that the efficiency of their creation would be useful for aerospace manufacturing.
“The front face of a reentry capsule gets super hot and those materials are super difficult to manufacture since they’re made by hand, and the only way to automate that process is with 3D printing,” Herren explained.
Their MAD3D printing technology offers a cost-effective alternative to traditional aerospace manufacturing methods by also outperforming other thermal protection materials, like aluminum, at half the weight.

Looking ahead, the team plans to scale up its operations in the coming year. Cowdrey expressed excitement about transitioning from a desktop proof-of-concept scale 3D printer to an industrial-scale, multi-axis 3D printer.
“That just means a big robot arm with our printing process implemented on that robot. So we can print bigger things and more reliably print those things,” said Cowdrey.
The move aims to facilitate production of materials, marking a significant step toward commercializing their product.
“It’s our MVP (minimum viable product),” explained Herren. “Right now, we’re still lab scale, we can’t sell the parts we print yet. So this thing will be able to print the parts that we can actually sell and have trials with customers.”
The most ambitious plan yet: a demonstration mission set for 2025.
One of their 3D-printed space capsules, designed to survive reentry from space, will be put to the test on a mission to go to the International Space Station.
“In 2025, our capsule will ride in the trunk of the Dragon capsule. The trunk burns up and then we’ll have our capsule come out during flight reentry,” said Herren. “Sensors and data transmitters will send us back the data to prove it is the first 3d printed object to survive reentry from space.”
The founders hinted at potentially streaming the event live or throwing a watch party for the coming demonstration mission.
