what kind of resin did you use? epoxy will bind most things, but if you use something like polyester resin it may not work so well, also keep in mind the curing time as well, that could affect your adhesion as well as how you applied the glass and the resin.
I did a more recent set of tests, with bonding epoxy, and it appears all four commonly used filaments bond will to plywood: www.jcrocket.com/printed-bonding.shtml
@@JuanSanchez-rb4qu Good question. I suspect that the fiberglass wrap wouldn't do much for the mechanical properties. But then again, one one can get strength from a core and stiffeners as we have done for a long time with foam: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5mUKQ7CUd8I.html Obviously, 3D printing will replace everything else eventually, so we just need to keep following the developments in materials and build volumes.
What are you actually trying to determine from this? I'm new to fibreglassing and would like to make some moulds using PLA. I would of thought that sticking is a bad thing?
Yes, sticking is be bad for making molds, but good for skinning 3D printed parts with fiberglass. You could probably make molds using PLA printed parts, but the surface irregularities would need to be filled.
Well for starters now I know I can integrate 3D printed pieces into my fibreglass props. He's just testing it so we know what happens without having to test it ourselves.
