If your are capable of printing the desired shape into a solid you could then use this to make a mold in silicone (RTV). I would look at using a urethane elastomer that has the desired durometer and color for your application. Selecting the proper RTV for your mold will enable thermally curing the final cast urethane part. If this approach is feasible for your application it would be in my view should be the least expsensive method.
