7:25 to me, 3D printing can replace the clay sculpting part of this process. It's great for prototyping and iteration (and mail a copy to the client for them to be able to look at and feel the actual 3D object and be able to say "I like this, but 10% larger"). But then use a final 3D printed model to make a mould for casting. That gives you the "proper" quality and feel of the final product.
