DENVER (WATKINS), CO — October 10, 2012 (Spaceport Colorado PR) — Front Range Airport, home to the future Spaceport Colorado, signed a Letter of Intent with Rocket Crafters, Inc. for horizontal launch, dual-propulsion, suborbital flight operations at this “remote, but accessible” general aviation airport.The Letter of Intent outlines a mutual intent to promote and develop Spaceport Colorado at Front Range Airport as the preferred commercial spaceport location in America’s heartland. Upon receipt of a spaceport license from the Federal Aviation Administration, Rocket Crafters intends to locate certain pilot astronaut and mission specialist training activities at the spaceport. Rocket Crafters further plans to conduct test flights of its planned Sidereus and Cosmos Mariner suborbital flight vehicles between Spaceport Colorado and the proposed Neil Armstrong International Air & Space Center, Titusville, Florida.

maybe some X- ATK people?address is in Utah.
ABS isn't just used for LEGO elements. It's also common in automotive applications and 3D printing. Smells bad compared to PLA, tho.
"We spent years working on tests and started rewickering," Fabian said. "We had been printing the fuel cylinders in stacked rings. But we learned that a horizontal, linear structure is easier and faster to print; it's more stable as you print it."The change at Rocket Crafters highlights the competitive innovation underlying this rapidly growing industry."It's secretive, yes. We don't share technology," Fabian said. "But there is a little back-channel talking just to make sure we're not stepping on each other's toes for patents."Rocket Crafters' engine design uses a 3D-printed plastic fuel core, which combines with nitrous oxide at ignition. That's different than many other rockets flying today that mix two flammable liquids. According to Rocket Crafters and others who have tested hybrid engines, they are safer because there's less risk of a catastrophic explosion."With this, there should be zero explosions," Fabian said.

There can also be cracks in the propellant causing an increase in pressure or burn through, rupturing the chamber. Also nitrous oxide can explode on its own under the right conditions.
An exciting morning at @RocketCrafters: A test firing of the company’s STAR-3D hybrid engine was safely aborted ~1.5 seconds post-ignition — still enough time for my cameras to capture images! I look forward to following & watching Rocket Crafters grow in the coming years.
HF-43: The motor ignited, stabilized, and fired for approx. 1.5 seconds. At that time the igniter housing pressure seal failed, causing the system to automatically shut down. Our team is working to adapt the design to prevent this from happening again. #RedefiningRocketScience
Rocket engine test in Cocoa sends debris flying, starts fireLoud boom reported by Cidco Road area business near Rocket Crafters’ test siteBREVARD COUNTY, Fla. – Rocket engine company Rocket Crafters was conducting an engine test Thursday that resulted in a mishap sending debris flying and starting small brush fires, company officials confirmed to News 6.
During a scheduled engine test fire shortly after 12:00pm today, Rocket Crafters suffered an over-pressurization anomaly.Per standard procedure, individuals were cleared from the test bay before the test, and no one on-site was injured during the incident.
We thank the City of Cocoa, The Cocoa Fire Department, and the Cocoa Police Department for their quick response time and commitment to safety. @CityofCocoa @cocoapolice

Looking in direction that debre departed after #RocketCrafters rocket test failure, then how close the facility is to #SpaceX #Cidco #Starship facility
Debre hit the tractor trailer in distance and not the fuel trucks, fortunately.
