Essentially, you build a grid of welders into your ship. The better way to handle this is to make your ships and bases self-constructing, but this takes quite a bit of thought to pull off, and forces you to design things differently than you might otherwise. This is likely to be very laggy, runs the risk of not fully welding up some blocks, and all around is not your friend.
The 'standard' way to automate blueprint manufacture in Space Engineers is to use a wall of welders attached to a piston or ship.
Depending on how you design your ships and bases, absolutely.
