The Engineer – First metal 3D printer heading to International Space Station

The logistical burden of resupplying future Moon bases with instruments or load bearing elements could possibly be alleviated if astronauts might manufacture such objects with a steel 3D printer.

To that finish, the primary steel 3D printer launched on January 30, 2024 onboard NASA’s mission NG-20, which is heading to the Worldwide Area Station on a resupply mission.

Within the coming days the printer can be set-up within the Columbus module – the science lab onboard the ISS – by astronaut Andreas Mogensen and operated to 3D print the primary metallic half in house.

The printer was developed by Airbus, AddUp, Cranfield College and Highftech Engineering beneath a European Area Company (ESA) programme.

In a press release, Gwenaëlle Aridon, Airbus Area Meeting lead engineer, stated: “Astronauts will be capable to immediately manufacture instruments reminiscent of wrenches or mounting interfaces that might join a number of elements collectively. The pliability and fast availability of 3D printing will drastically enhance astronauts’ autonomy.” 

Sébastien Girault, steel 3D printer system engineer at Airbus, stated the printer is the dimensions of a washer and might print elements which are 9cm excessive and 5cm extensive.

In addition to overcoming the problem of measurement, the printer will sit in a sealed steel field to guard towards the aggressive printing setting attributable to the laser and the warmth it generates.

“Gravity administration can also be key, which is why we selected wire-based printing expertise,” stated Girault.

Moreover, fumes which are emitted can be addressed by filters and captured contained in the machine in order that they don’t contaminate the air contained in the ISS.

Two printers can be used for this experiment: the ‘flight mannequin’ contained in the ISS; and the ‘engineering mannequin’ on Earth. The astronauts will print 4 samples in house, which can be despatched again to Earth for evaluation. The identical specimens can be manufactured utilizing the engineering mannequin printer. 

“To be able to consider the results of microgravity, ESA and Danish Technical College will carry out mechanical power and bending exams and microstructural evaluation on the elements made in house and examine them to the opposite specimens,” stated Girault.

In keeping with Airbus, there are a number of plastic 3D printers on board the ISS and Astronauts have used them to interchange or restore plastic elements that might have taken months to reach if constructed and transported from Earth.

This logistical constraint will intensify on future Moon and Mars stations; the uncooked materials will nonetheless must be launched, however printing the half remains to be extra environment friendly than transporting it to its vacation spot.

“Growing the extent of maturity and automation of additive manufacturing in house could possibly be a sport changer for supporting life past Earth,” stated Aridon. “Considering past the ISS, the functions could possibly be wonderful. Think about a steel printer utilizing reworked regolith or recycled supplies to construct a lunar base.”
