CAPE CANAVERAL, Fla. (AP) — A rocket built almost entirely from three-dimensional parts was ready for launch Wednesday during its maiden launch.

The California company Relativity Space is trying to launch a rocket into orbit from Cape Canaveral.

It’s a relatively small rocket, only 110 feet (33 meters), and it won’t be carrying anything for this test flight.

About 85% of the rocket, called Terran, is made of 3D parts printed at the company’s factory in Long Beach, California, including its engines. Relativity Space aims to increase this percentage in its future versions.

SpaceX’s Falcon rockets have been flying with 3D parts for years, but nowhere near as much as Relativity Space’s new rocket.

Relativity Space said its rocket is the largest 3D-printed object in existence and is attempting orbital flight.

Businessman Mark Cuban of TV’s “Shark Tank” was one of the first investors in the company.
