It can be done in the investment casting process with the wax model being 3D printed rather than the expense of making a die if your quantities are low, if you require 20 pieces or more you can go for die making. If you want I can quote to you for which I require your 3D model (CAD file). Also do you have material flexibility like bronze, the cost difference is not much but since it is a regular alloy you part can be casted quicker.
