The world's first 3D-printed rocket launched successfully on Wednesday, marking a step forward for the California company behind the innovative spacecraft, though it failed to reach orbit.

Billed as less costly to produce and fly, the unmanned Terran 1 rocket launched from Cape Canaveral, Florida at 11:25 p.m. but suffered an "anomaly" during second-stage separation as it streamed towards low Earth orbit, according to a livestream broadcast by aerospace startup Relativity Space.

While it failed to reach orbit, Wednesday's launch proved that the rocket – whose mass is 85 percent 3D-printed – could withstand the rigors of lift-off.

The successful launch came on the third attempt. It had originally been scheduled to launch on March 8, but was postponed at the last minute because of propellant temperature issues.

A second attempt on March 11 was scrubbed due to fuel pressure problems.

Had Terran 1 reached low Earth orbit, it would have been the first privately-funded vehicle using methane fuel to do so on its first try, according to Relativity.

Terran 1 was not carrying a payload for its first flight, but the rocket will eventually be capable of putting up to 1,250 kilograms into low Earth orbit.

The rocket is 33.5 meters tall with a diameter of 2.2 meters.

Eighty-five percent of its mass is 3D-printed with metal alloys, including the nine Aeon 1 engines used in its first stage and the one Aeon Vacuum engine employed in the second.

It is the largest ever 3D-printed object and was made using the world's largest 3D metal printer, according to the Long Beach-based company.

Built in 60 days

Relativity's goal is to produce a rocket that is 95 percent 3D-printed.

Terran 1 is powered by engines using liquid oxygen and liquid natural gas – the "propellants of the future," capable of eventually fueling a voyage to Mars – the company said.

Relativity is also building a larger rocket, the Terran R, capable of putting a payload of 20,000 kg into low Earth orbit.

The first launch of a Terran R, which is designed to be fully reusable, is scheduled for next year.

Relativity said its 3D-printed versions use 100 times fewer parts than traditional rockets and can be built from raw materials in just 60 days.
