CAPE CANAVERAL, Fla.—A rocket made almost completely of 3D-printed parts came within a half-second of blasting off Saturday on its debut flight, but remained grounded after back-to-back launch aborts.

The engines ignited, but abruptly shut down, leaving Relativity Space’s rocket, named Terran, standing on its pad.
