Your forgetting one important aspect of the equation. Cash.
People in the game have an overabundance of it, they have talked about a money sink but have had no success
Economy is supply/demand based, there is plenty of supply but no demand, its simply easier to buy or rip the parts for a build.
The only way I see to make it work is for builds to be anything over 100%, that it be required the build be made from all ores, complete scratch build
Now that raw ore has value, the risk needs to adjusted, more/tougher mobs
The selling price of 200% items would prob remain as it is, cost + tip (builders are nice, enjoy what they do and already have an excess of cash)
Many other things are needed as well, printable items need to be harder to come by, way harder. The system would have to be wiped and restarted to remove current prints and wealth. Known items need to be relocated. And the biggest obstacle of all, a much much larger player base.
