Plat 55 is a platinum base, high durometer (stiff) silicone that is great for making multi piece molds or whenever good location, dimensional stability, or alignment is needed. It is also the rubber of choice for using when injecting foams as it will not move or flex under the pressure of the foam expanding inside.
I'm starting how to make that advanced Whiggley mold next week. Originally we did it by 3D printing the different sides and then simply molding the 4 SLA prints but I understand that is not a common tool people have at their disposal, so I will clay them up by hand and show you how to make a 5 piece mold.
Perhaps I will do it in my latest Whiggley design which is a bigger profile just to show you something different.
Hopefully have the video put together for you in a couple weeks.
