There is still time to get involved and help build Ryan’s prosthesis! We really need help from someone with experience of vacuum forming silicone!

I can look at this for hours, what and amazing bit of mechanical engineering.
silicone (RTV) is casted for molds, used for membranes (not rtv) on vacuum forming…
@Aria_C_Bramanta Yes, a membrane is exactly what we’re trying to make.
Well I just found out you could use silicone for the membrane (or any other applications), but downside is you need to properly mixes the rtv(really mix it…but don’t forget pot life), then pour to a piece of perfectly flat glass for uniform width (assuming the flat surface is coated with some type of talcum powder for release later) let it dry out, optionally some rubber screen could be put as an internal flexible structure (the ones used for shirt prints screen with a fine mesh) then pour some more silicone rtv… But I have no idea of the performance, since I only use rtv for mouldmaking, I got rtv rubber on my cotton shirt (soak thru) and it sticks like crazy, not easy to pull apart, make sure you pour from center, and let it flow side to side (dont try to compensate and pour on the side) silicones are relatively slow to dry (overnight or depends in the product sheet) and tends to flow even really tiny spaces, you should compensate for overflow with carefully arranged cup (to hold excess silicone) though it might be tedous and hard to understand hiw this works, plain logic should come in handy, makes small batches before creating big or larger surface areas
@Aria_C_Bramanta this is awesome, can you email me so I can add you to the project? Everyone would find this really interesting. y email is cameron@wevolver.com
