Rocket Labs is also trying to 3D print rockets. Relativity Space is making a rocket that has 4 times the thrust of the Rocket Labs rocket. Relativity rocket engine will still have ten times less thrust than the SpaceX merlin engine.

Relativity Space wants is reimagining the way rockets are built and flown with massive 3D printing.

* 1000X fewer parts.
* 10X faster iteration
* entirely 3D printed

In 2017, the first complete printing of their rocket reduced vehicle part count from nearly 100,000 to under 1,000 components – and was first step toward an entirely autonomous factory.

The Aeon rocket will have less than 100 components and is 1000 times simpler than other rockets.

They are accelerating the design process by removing barriers between the digital and physical worlds.

Nextbigfuture covered Relativity Space back in October of 2017A

RELATIVITY is making the first autonomous rocket factory and launch service

They are an orbital launch company that will deploy and resupply satellite constellations with industry-defining lead time and cost.
Their entirely new process to build and fly rockets will redefine how we access space to connect our planet.
Relativity's technology builds toward our long-term goal of 3D printing the first rocket made on Mars.
