3D Printing Benefits in Aerospace
3D printing is an attractive technology that offers advantages over traditional construction techniques, especially when it comes to the final appearance of a part. "This technology makes parts lighter," says Johannes Homa, CEO of Austrian 3D printer manufacturer Lithoz. Thanks to the freedom of design, printed products are more efficient and require fewer resources. This has a positive impact on the environmental impact of part production. Relativity Space has demonstrated that additive manufacturing can significantly reduce the number of components required to manufacture a spacecraft. Take the Terran 1 rocket as an example, saving 100 parts. In addition, this technology has significant advantages in terms of production speed, with the rocket completed in less than 60 days. By comparison, building a rocket using traditional methods can take years.
In terms of resource management, 3D printing can save material and, in some cases, recycle waste. Finally, additive manufacturing could be an invaluable asset in reducing rocket take-off weight. The goal is to maximize the use of local materials, such as regolith, and minimize the transportation of materials in the spacecraft. This makes it possible to carry only a 3D printer, which can create everything on-site after the trip.
