Hello everyone

I am working on a full suspension bike frame and my design requires some inserts that will be placed inside the tooling that need to be dissolved or mechanically removed after curing, due to negative draft angles.
The insert needs to resist to at least 80°C and 3 bar of pressure during the cure cycle. surface requirements are not critical for this project. Ideally it would be something that can be cast in a 3D printed mould, machining is an option too.

The best would probably be just to use aquacore, but with the minium ordering quantities I am inclined to figure out a MacGyver solution instead.

Does anybody already have a secret recipe, or an idea what could work? I tested a couple things and have some routes, but i figured id ask here as well.

In any case i will share my findings at a later stage.

Ciao!
