I completely agree with these comments. If you're looking to prototype a new figurine or want to offer a small number of figurines, then 3D printing could be more cost effective than using molds. But if you're going to print the same figurine in large quantity, then a mold will likely be faster and more cost effective.

If you do elect to use 3D printing for prototypes or small runs, you might look into the post processing required for your prints (e.g., removing support material) and the time required for reliable printing (e.g., do you need to manually calibrate before each print) before deciding on a 3D printer.
