I am not an engineer or clever at building so I have to research. Instead of building up Sunny’s beak with layer upon layer of material it make sense to 3D print it! This technology is so Star Trek it boggles the mind! If you can conceive of a shape odds are it can be printed and in an amazing selection of materials.
Much of what I read on prosthetic beaks were that they broke or wore down over time and had to be replaces. Not acceptable. The beak replacement require that the bird be under general anesthesia and that is more
