The Shenyang Institute of Automation is developing a method to 3D print and weld carbon fiber reinforced PEEK for use in space. This approach allows for the construction of large, durable structures directly in orbit, reducing the need to launch massive, pre-assembled components from Earth. By combining additive manufacturing with thermoplastic welding, the process creates high-strength components capable of withstanding extreme space environments. This technology could significantly lower the cost and carbon footprint associated with space infrastructure deployment.

Printing in orbit sounds great, but I want to see the power requirements for the welding process. If they need massive energy arrays just to fuse the PEEK, the mass savings on the structure might be offset by the power system weight.

True. Also, how do they handle the surface finish? If this is for structural frames, it is fine, but if they want a precision fit, they will need a way to machine or sand these parts in zero gravity.

The real value here is the reduction in launch frequency. Fewer launches mean less atmospheric soot and propellant emissions. It is a practical way to scale space infrastructure without scaling the environmental impact of the lift phase.

Interesting use of carbon fiber. Usually we talk about it for wind turbines or EVs, but on-orbit manufacturing is a different beast. Curious if this PEEK blend is recyclable once the structure reaches its end of life.
