The Groundbreaking Advancement of Metal 3D Printing in Space: A New Era for Astronauts and Space Agencies

The European Space Agency (ESA) is set to make history with the launch of the first metal 3D printer to be used in space. The Cygnus NG-20 supply mission, which carries the 180kg (397 lbs) printer, took off on Tuesday, January 31, 2024, and is scheduled to dock at the International Space Station (ISS) on Thursday. This marks a significant milestone in space exploration, as metal 3D printing in orbit poses unique challenges compared to its terrestrial counterpart.

Andreas Mogensen, an astronaut from the European Space Agency, will install the printer, which Airbus developed for the European Space Agency. Once installed, the printer will be controlled and monitored from Earth. The machine’s development represents a crucial step forward in the application of additive manufacturing technology in space.

Polymer-based 3D printers have been employed on the ISS in the past. However, metal 3D printing in orbit is a more complex endeavor. The machine will use a form of stainless steel, which is often used for water treatment and medical implants due to its excellent resistance to corrosion. The printer melts the stainless steel wire using a laser that is a million times more powerful than a typical laser pointer. The melted metal is then added to the print.

The melting point of the metal is around 1,400°C, and the printer will operate inside a completely sealed box. Before the printer can function, it needs to vent its oxygen into space and replace its atmosphere with nitrogen. Otherwise, the melted metal would oxidize when exposed to oxygen.

The safety of the crew and the ISS itself must be ensured, as the higher temperatures employed compared to a plastic 3D printer (which heats to around 200°C) necessitate stringent precautions. Maintenance possibilities are also limited, and if successful, the strength, conductivity, and rigidity of metal would take in-space 3D printing to new heights.

Four test prints are scheduled. The printer will replicate reference prints that have been created on Earth. The two versions will be compared to help scientists understand how printing quality and performance differ in space. Each print will weigh less than 250g (8.8 ounces) and be smaller than a soda can, but it will take the printer between two and four weeks to create each one. The printer will only be in operation for a maximum of four hours each day due to its fans and motor being fairly loud and the ISS having noise regulations.

If the experiment proves successful, it will pave the way for astronauts and space agencies to print required tools or parts without having to send the items on resupply missions. Metal 3D printing could also help with the construction of a lunar base using recycled materials or transformed regolith (moon soil and rock). It may come in useful for missions to Mars as well.

The European Space Agency’s groundbreaking initiative represents a significant leap forward in the application of additive manufacturing technology in space. The successful implementation of metal 3D printing in orbit could revolutionize the way we approach space exploration and infrastructure development.

In conclusion, the European Space Agency’s launch of the first metal 3D printer to be used in space marks a pivotal moment in the history of space exploration. The successful implementation of this technology could lead to numerous benefits, including the ability to print required tools and parts in space, the construction of lunar bases using recycled materials, and the potential application of metal 3D printing for missions to Mars. The future of space exploration is undoubtedly exciting, and the European Space Agency’s groundbreaking initiative is a testament to the limitless potential of human innovation.
