I'm reviving this old thread to see if anyone ever got around to trying silicone webbing? I've been working with silicone a lot lately for molds and masks and just about everything. The material is expensive, but really versitile, and nigh indestructible once cured.
if no one has tried it yet, does anyone have some advice on how to make the molds? Does it need to be cut into aluminum? Would MDF work with a couple coats of shellac? How big of a CNC machine do you need? Is there a specific bit to get the right shape? It's a long shot, but does anyone have the tool path files? I just made a CNC machine that runs on grbl so if anyone has the gcode already I could give it a shot this week. I've been struggling with funding a CAD/CAM software I can make sense of. I can build just about anything, but when it comes to 3D modeling software, I'm barely a step above useless.
