Researchers from German institutes are planning to send a robotic mobile selective laser melting (SLM) printer to the Moon, to demonstrate in-situ additive manufacturing using lunar regolith as a feedstock.
The project is carried out by engineers from the Hannover Laser Center (LZH) and the Berlin Technical University (TU Berlin), and the technology has already been demonstrated successfully on Earth, using simulated lunar conditions.
You can see a render of the robot in the image below.
