What material should I use to make a mold for ABS injection molding?
I want to design a mold to be used for ABS injection, but I'm not sure which material would produce the best results. I want to design it and upload it to a manufacturer like shapeways or i.materialise. They have a few different materials to choose from here
for shapeways, and here
for i.materialise. What do you suggest would be the best material for a mold used to create professional looking ABS parts?
