Flexible resin resistent to fuel?

Hi everyone,

I need to print a large part with flexible resin and it doesnt fit into formlabs so I need to split in several subparts. The part has a thin wall (2 mm), its like a flat sheet that need to be glued by the walls, so my questions are:

1_ I read that some users have used raw resin + laser pinter to make the joint, ¿how does this kind of joint work in such a thin walls?
2_ The part need to be fuel resistant, as in material datasheet I dont see any related to that, does anyone know wheter the resin is fuel resistant?


The thinner is is, the more seamless the joint. Curing liquid resin with a 405nm laser will only go so deep into the material so it’s no use to try to cure the inside of a Ø5mm torus as the laser will only cure the surface. It’s better to glue before post-curing and post-cure the while parts.

No idea for fuel compatibility.

You should check out this thread on various adhesive options.

What sorts of compounds are you working with? We don’t have compatibility for testing for Flexible Resin, but for most of our other materials, 24 hour weight gain with diesel fuel is less than 1%. Flexible Resin is likely to have higher absorption values than our other materials, and you might run a few experiments with your specific application to see how this performs.
