Wood glue is so effective because it soaks into the pores in the wood. This gives it a lot of surface area to hold the parts together. Wood filament isn’t nearly as porous as actual wood so wood glue won’t hold it as strongly.
Might work ok depending on what exactly you’re gluing but you’d probably be better off using 2 part epoxy.
Thanks!
For holding parts together I'd just use CA glue.
Edit: CA glue is also used to quickly bond wood too (while wood glue dries/cures) so it should be fine on wood filament.
What is CA glue? Super glue?
Yes
I dont know, but also I think it woudnt be strong bond. Wood glue is shit for anything other than wood. I believe you need the same glue you would use for the same plastic with no wood.
It's sawdust mixed with plastic, by my understanding, so it doesn't have the porosity or structural solidity of wood. I'd stick with superglue, epoxy, or a construction or industrial adhesive—something that will bond both wood and plastic.
So… going to preface this by saying it’s not the best… but you “can” use pva glue (white glue and “wood” glue are the same thing- pva) but it’s not as strong a bond.
The trick is to make the surface extremely rough so the pva had something to stick to.
Most kinds of glue will require some scuffing, too.
Also if the part flexes, barges cement will be better than CA. Barges is useful if you want to have very neat glue ups- you paint it onto both parts in a thin layer then let it dry. It adheres to its dry (but still “live”) self but not much else.
