Nikon Sets Its Sights on Space Additive Manufacturing

Every kilogram to orbit costs a fortune

Launching hardware into space remains expensive, so aerospace engineers have spent decades trying to build lighter spacecraft. The next step is not lighter parts launched from Earth, but parts printed in orbit. Nikon Advanced Manufacturing believes metal additive manufacturing is the technology that will make that possible.

Hamid Zarringhalam, CEO of Nikon Advanced Manufacturing, told 3DPrint.com that space is one of the most compelling uses for additive manufacturing because the industry demands lightweight, high-performance components, rapid iteration, and resilient supply chains. All three are areas where 3D printing has a real edge over conventional machining.

Replacing resupply missions with digital designs

Future commercial space stations will need replacement parts, specialized tools, and upgrades throughout their operational lives. Waiting for cargo missions from Earth creates delays and forces operators to stockpile inventory. Additive manufacturing offers a different path: transmit a digital design and print the part on demand.

Zarringhalam sees this as an operational and safety advantage, not just an efficiency gain. The long-term vision is a digital manufacturing ecosystem where qualified designs are produced where and when they are needed. That same principle is already emerging in defense, aviation, and energy on Earth.

Metal AM systems are already in orbit-adjacent workflows

Nikon says its metal additive manufacturing systems are operating at several leading space companies today. That gives the company direct insight into how the industry is evolving. As launch costs fall, Zarringhalam expects additive manufacturing to become even more important for lightweighting parts and producing components that cannot be manufactured conventionally.

Manufacturing inside a space station introduces challenges that do not exist on Earth. Structures too large or fragile to survive launch forces could be printed in microgravity. Material behavior in vacuum, thermal cycling, and radiation resistance all need validation. But the basic logic is sound: if you can print it in orbit, you do not have to launch it.

A broader push beyond prototyping

Nikon does not treat space as a separate business line. The company sees it as part of a larger shift toward industrializing additive manufacturing across critical sectors. That mindset is visible in its acquisition of Nikon SLM Solutions, its new AM Technology Centers in Long Beach and Japan, and partnerships with ArianeGroup and Rocket Lab for ultra-large-format metal printing.

Whether in-orbit manufacturing becomes routine is still years away. Commercial stations like Vast's Haven-1 are targeting launches in 2027, with permanent habitation goals by 2030. Nikon is betting that by then, the printers and digital supply chains will be ready to support them.
