German aerospace start-up relies on additive manufacturing

3D-printed engine components for the trip to the moon

1 February 2024

Trumpf and the European space-travel start-up The Exploration Company are cooperating on the construction of core components for spacecraft for missions in the earth’s orbit and to the moon. As early as spring 2024, the Exploration Company will use 3D printers from the laser specialist to additively manufacture core components of the Huracán and Mistral engines for the Nyx Earth and Nyx Moon spacecraft in Planegg near Munich.

The aim is to make the Huracán engine reusable and refuelable in orbit with bio-methane and oxygen. “Our aim is to offer space missions more cost-effectively than was previously possible,” says Hélène Huby, CEO of The Exploration Company. The start-up plans to send a space capsule to orbit the earth for several months in an initial mission in 2026. Starting in 2028, further missions are planned to go to the moon. The spacecraft will initially carry freight, but in the long term, people will also fly on board.

Already 65 million Euro raised

The start-up has so far raised 65 million euros from private and public investors. The European company employs a total of around 120 people at its sites in Planegg near Munich and Bordeaux. Commercial space travel is considered a growth industry. Trumpf predicts that the global market for the production of aircraft and spacecraft would grow to 740 billion euros in 2023.

“If you want to be successful in the space-travel industry today, you have to use Additive Manufacturing,” says Tobias Brune, who is responsible for the additive manufacturing business at Trumpf. Designers use AM to combine entire assemblies into a single component. This saves weight and reduces complexity. Every gram saved reduces fuel costs. What’s more, the less complex components reduce the cost of safety tests before the rocket launch and increase the probability of a successful mission in space. 

Saving time and raw materials

With the help of 3D printers, The Exploration Company saves valuable raw materials. The systems only use the material that will ultimately fly into space. In the past, aerospace companies produced components using conventional manufacturing methods such as stamping, forging and casting. Much of the material ended up as waste.  

Additive Manufacturing enables rapid prototype development, which normally takes a lot of time in the aerospace industry. The 3D printer can produce new prototypes within a few hours. With conventional manufacturing methods, the production of some of these complex geometries would not be possible or it would take up to several weeks or months.
