I would need to see that to really understand it.
I am familiar with the ‘printing’ capabilites of many home computers, but not for something as detailed as Satellite Antennas.
That is ingenious! Just haul raw materials to orbit, 3D print your antenna structure, and let solar UV do the curing. You can build structures larger than the rocket fairing.
How long before they can print solar cells for power generation. I worked for a company once that was able to print solar cells.
