Building a rocket is a big operation, even when you’re printing them from the ground up, like Relativity Space [1]. The launch startup is graduating from its initial office, which is a bit cramped for assembling rockets, to a huge space in Long Beach where the company will go from prototype to first flight.

We recently visited Relativity at their old headquarters, which had the scrappy (literally — there were metal scraps everywhere) industrial feel you’d expect from a large-scale hardware startup. But except for the parking lot, there didn’t seem to be anywhere to put together… you know, a rocket.

So it was no surprise when co-founder and CEO Tim Ellis said that the company was just starting the process of moving to a gigantic new open-plan warehouse-style building in Long Beach.

Relativity CEO Tim Ellis is obviously excited about the new HQ.

“It’s a big step,” Ellis told TechCrunch. ” It’ll actually be the first factory we fully build out with 3D printers. This new space is actually big enough that we’ll be printing the first and second stages, and the fairing at the same time. The new ceiling height is approximately 40 feet, which will allow us to build taller – about twice the height of our current facility. We’re on track to start shipping parts to Stennis for testing later this year.”

In addition to the three “Stargate” printers that can print parts up to 15 feet high, they’ll have three more that can go up to 20 feet and two that can go up to 30. It’s a bit hard to imagine a single printed rocket part 30 feet tall until you’ve seen some of the pieces Relativity has already made.
