Now that 3D printing is so common, replicating models and creating prototypes have become so much easier compared to how things were done a couple of decades ago. However, it’s still worth our time to take a look back at the more old-fashioned methods and come up with ways to incorporate our new technologies with them.

One of the oldest methods to replicate a model is investment casting, or lost wax casting. This method involves making a prototype made of wax, from which a mold is made using refractory materials.
