It looks like I'm going to be involved in designing/developing some prototype tooling to be used in a cold isostatic press for the compaction of metal powder.
Though I can follow some design guidelines, I still expect some trial and error to be involved in reaching the final 'bag' geometry. I'm wondering if there are any 3D printable elastomers available that might be suitable for prototype bags. Anyone here have any experience of such materials? I'd be looking at bureau printing, not buying a printer.
My other thought was perhaps to 3D print wax patterns to 'cast' single part polyurethane bags around. I am happy to consider other options if anyone has any bright ideas.
