      There are commercial people who basically 3D print low volume moulds.
      It's cost effective for a few hundred items in certain formats.

      We still have a variety of UK toolmakers, dunno what the US situation is
      like. Over here it's mostly the more specialist and complex mouldings
      that you can no longer get produced.

        A year or so ago N-Scale magazine had a long article on making a molding

        make the molds from handmade or copied prototypes. Molded items were
        thin and fairly small but it worked.

            Ed,

            I think I've seen that, too. My impression is that even milled aluminum molds have a very limited lifespan, and I am going to want to make thousands of shots. My belief is that is way more than an aluminum resin, and perhaps even more than a milled aluminum mold could do.

            On the other hand, Bowser insisted on making me a chrome steel mold guaranteed for a million clean shots (I think the price mentioned was $15k, at which point I almost fell off my chair). I told them that if they guaranteed I'd live long enough to sell a million, I'd pay the price, because it would be a guarantee of immortality.

                Aluminum can do 1,000's if the right grain and treated like T3. Aluminum is generally $5K a pair. Add-on details (slides), accessories (roof walks, railings, trucks, etch.) and you spend easily another $5K+. Most anywhere in the world now.

                  Malcolm,

                  Just a thought, if you have the drawings ready to go there are 100s of CNC Mills on the secondary market, lightly used from a very soft market, everything from bench top to room size.
                  Thinking out loud,
