To make enough shots for a low unit cost, the mold has to be made of very hard steel. So that takes a long time on a very expensive cnc. If you make it out of softer material to make the mold less expensive (ie aluminum), you only get ~100s shots or so. Good enough for testing / beta runs, but not enough to amortize the engineering & cnc costs.
