A small start-up based out of New York's Brooklyn Naval Yard is staking its claim among the next generation of rocket companies: By developing a rocket engine that it says is the world's largest 3D printed in a single piece.
The simply-named company, Launcher, provided CNBC with a first look at the company's E-2 engine, which was made in Germany by AMCM using its specialized M4K printer. Launcher only has five full-time employees but credits its ability to develop E-2 quickly to the advances made in additive manufacturing — otherwise known as 3D printing.
"With 3D printing, we're now in a world where a start-up like us can now access [advanced] liquid oxygen propulsion technologies," Launcher founder Max Haot told CNBC.
Haot founded Launcher in 2017, after he sold his internet video business Livestream to Vimeo. Launcher plans to spend a decade building a six-story tall rocket that will send small spacecraft to orbit. Launcher's rocket is priced to that smaller market as well, with plans to sell missions for about $10 million a launch.
Beyond Launcher's headquarters in Brooklyn, the start-up has a test facility on New York's Long Island, at the Naval Weapons Industrial Reserve Plant. Launcher has completed several minutes worth of test fires of its E-1 engine out on Long Island. The company expects to begin test firing the E-2 engine in the second half of this year.
The E-2 engine is the key next step in Launcher's plan if test flights are to begin in 2024. It's a "closed cycle" combustion system, which Haot said is "the most powerful" engine system. This is the same approach-SpaceX's new Raptor engine uses, to eek out the most efficiency out of an engine as is possible.
3D printing parts will also help Launcher's development timeline. AMCM took "about a week" to print the E-2 engine, said AMCM's head of sales Christian Waizenegger. This makes M4K the first of its kind, as it combines high quality machining with the ability to print large parts.
There is controversy about whether E-2 is the world's largest rocket engine that was 3D printed in a single piece. Other rocket start-ups are using 3D printed technologies to widely varying degrees. For example, Los Angeles-based Relativity Space is working to build nearly entire rockets out of 3D printed parts. And U.K.-based Orbex unveiled an engine earlier this month it claims is "the world's largest. Like Launcher's E-2, the Orbex engine was manufactured in a single piece.
But Haot believes Launcher's engine is notably bigger than Orbex's. Both Haot and Waizenegger pointed to the known capabilities of the 3D printing company SLM Solutions that built Orbex's engine. SLM Solutions' printer is only capable of printing an engine about half the size of E-2, according to Haot and Waizenegger.
"I don't know any other machine that can do this," Waizenegger said of his company's M4K printer.
While E-2 was printed to Launcher's specifications, Waizenegger was careful to point out that his company's business is building printers, not rockets. Th E-2 was the third demonstration part that M4K has printed. The M4K printer and E-2 engine were developed independently, but the former needed to print parts to demonstrate its abilities to potential customers. That's where Launcher came in.
"This is not a rocket-specific machine," Waizenegger said. "This machine [M4K] has been developed independently from Launcher."
