Quoted from vid1900:If we had an order of around 50, I could get them cast in aluminum.
The form would need to be in 2 halves.
But, remember that aluminum shrinks after casting, so the form needs to be oversized ( I seem to remember the model needs to be oversized 1.12) and because it would be a sand casting, you loose a little of the dimensions to polishing.....
So, you could 3D print the design at 1.12 original. Does the sand casting preserve threads or does it leave an undersized hole to screw into?
Very cool stuff.
