Solid Design was one of the more interesting booths at the recent Wonder Festival. I wanted to write them up separately to highlight what they're doing. Typically in the toy making process, you sculpt a figure, and a wax proto is made from that sculpt. The wax is then used to make the copper molds which are ultimately used to pull the vinyl.
Well, Solid Design is selling wax (which one would assume has some special properties + composition) that you can directly sculpt from. That cuts a step out of the toy making process. You can go directly from the sculpting stage to the mold making stage.
I'm not sure which method or sculpting material works the best (this or the traditional sculpt --> wax--> mold process), but I figure the more knowledge that's out there the better.
They have a pretty extensive website (all in Japanese though) where their products are introduced and sold.
