School me on rotocasting

Hi everybody, like the title states, I’m wanting to know everything about rotocasting, how the process works, what materials are used, etc. I would also like to know if there’s any websites that I can refer to for further information. Also, I was wanting to know what materials are commonly used to make molds, and what material is used to make the model. I’m interested in casting vinyl or resin figurines. All info is greatly appreciated so thanks in advance!

The Google is your friend…

stick with resin home brew vinyl is not realistic toxic and messy

Have a look on Youtube… may be a video or two.

As for materials, Polyethylene is the most common material. Almost all thermoplastics really (Polyamide, Polypropylene, PVC), all inserted in powder form. heated to about 250 degrees C.
