Hello all,
I am trying to start a business with a frined in plastic miniatures on 28mm scale. This kind of miniatures http://www.1-72depot.com/wp-content/...99417427_o.jpg

I am in the procces of building a simple cylinder/piston plastic injection machine and we have started developing the models in Blender.

Now we are stuck with deciding which way to go regarding the mold making, we have thought about SLA 3D printers and CNC machines but we cannot find anything that will provide enough detail, and we don't know if it is a case of we are underestimating the capital needed or there isn't something at hobbyst/desktop level.

We wouldn't have a problem on purchasing a 5000€ machine in Europe if there is one that can deliver this kind of quality.

As an example this head might be 5mm tall so we need an accuracy or resolution in the microns scale. So whatever surface we do is completely smooth and doesn't look like this. https://cdn.instructables.com/FVY/X0...RR7.MEDIUM.jpg

Another problem we have found with CNC machines is that the plastic injection machine has to have an angle, so effectively those surfaces will look like stairs, so the better the resolution the straighter it looks rather than stairs like.



Any help or recomendations would be appreciated.
