I see that people don't get that printing thing, which is a shame as it is used quite a bit anyway - for example food cartridges. We can review and change if needed, to be honest the feature is what is important in this instance. Yes, I appreciate the difference in scale, and as I mentioned before we're not talking about a single machine that just spits out a ship, it combines more economical processes as well.
The thing about 'printing' that I can't get my head round (aside from the scale of the technology, and the fact that it makes technology-based commodities trading redundant), is that it's producing a copy of something from a template. That means, if I 'transfer' my ship, I've actually now got two of that ship. If I transfer again there will be three etc. etc.
Spaceports would quickly be rammed full of unwanted ship copies. Also, why have the Pilot's Federation, when stations would be giving all of these unwanted ships away to passers-by just to keep the bays clear?
