With resin 3D printing, I can produce a complex case for my product, although at a higher cost per unit than injection mold - but with no up-front costs. It seems fairly cost effective considering the extremely high cost of making an injection mold. I'm not at the scale of needing 100,000 or 1mil units though. Right now it's costing me $5 per complete case (5 parts, $1 each - it isn't a very large case). I can have 10,000 of these cases made for about the same price as it costs to create the injection mold. I'm nowhere near the scale of 10,000 units right now, but maybe in the region of 1,000 units. The cost does get passed on to the customer and if I ever get an investor and serious traction in the market then the injection mold will sort itself out and the per unit cost for my product will go down.
