Hello @ben_van
Hopefully this is the most appropriate place to post.
As per our previous discussion, I am looking to fabricate some lightweight sections of a UAV wing. With the hot wire cutter not available at the moment, would the use of spray foam be an apt substitute? The idea is to 3D print a mold (using Vase Mode on a Slicer) and then fill it with the kind of expanding foam one would use at a constrution site (available at Bunnings). If this could work, it could save much time 3D printing a wing structure with internal supports (1/5th of the original time), and also provide the ability to generate numerous copies relatively quickly and cost effectively. Refer to the image, it is a wing structure with internal supports. So the expanding foam should replace all those supports (but space will be needed for simple cutouts for spars, servos etc).

Thanks
