From Zero to Space: How 3D Printing is Changing the Game in the Space Industry

If you think you've seen it all when it comes to tech, turn 180 degrees and look at the sky. What is rising is not a bird, nor a plane. It's a rocket, but not just any rocket: it's a 3D-printed rocket from scratch! The question that remains is: will this wonder really cross the atmosphere and reach space?

The phenomenon called Terran 1

We are not talking about just any project. This is Terran 1, the world's first 3D printed rocket. The person who brings this innovation to life is company Relativity. It took five years of arduous development and, in the end, 85% of the rocket's parts were manufactured exclusively by 3D printers. Even the first stage is entirely made of printed parts.

Now, you might be wondering, “How do you print a rocket that actually flies?” Well, not just any “plastic” will withstand the pressures and temperatures of space. A Relativity bet on two key materials: an exclusive type of aluminum for the body and a special alloy of copper, chromium and niobium, courtesy of NASA.

No glue, just technology

The most incredible thing is that the printing is done without a drop of glue. The process uses two techniques: laser powder bed fusion and directed energy deposition. The first creates strong, detailed pieces, while the second is ideal for large pieces. And so, as if by technological magic, the rocket takes shape.

But don't think that this story is all about success. On March 22, 2023, the rocket took off. It went up, up and… well, it didn't reach space. The second stage engines failed. But all is not lost: the rocket survived the Max-Q, the point of greatest stress during the climb.

“But why go to the trouble of 3D printing a rocket?” you might be asking. Simple: it's faster and cheaper. If something goes wrong, just change the code and print again. No sending it to the manufacturer and waiting months for an adjustment. O cost-benefit is so good that even professionals in the field are full of praise.

About Relativity and NASA

A Relativity is the company responsible for this innovation that could be a game changer in aerospace. With a relentless focus on research and development, this North American company has invested in cutting-edge technologiesto take the Terran 1 rocket from the field of idea to the sky. The blend of proprietary metals and implementation of 3D printing methods are a testament to the innovative spirit that drives Relativity.

We cannot ignore the role of NASA, which has always been a pillar in the field of space exploration. The organization not only inspired many of the technologies used, it also invented the three-piece engines that made this feat possible. Even if indirectly, NASA's past expertise and innovations continue to pave the way for new giant leaps for humanity.
