I'm in the process of standing up a laser cutting service for the rocketry hobby. One thing I'm learning is finding 1/8" baltic birch plywood that is not laughably warped is very difficult. In all the places i've looked around town and orders i've placed online only around 10-20% of it has been usable. The situation for 1/4" is a little better but you're still hand picking pieces out of a stack which is very time consuming especially for a material inventory.
I placed an order tonight for some samples of MDF core plywoord, basically MDF with a veneer of Maple on both sides. MDF, while not as strong, is at least more stable and hopefully flatter than what i've been able to find so far. Then the Maple veneer hopefully means sanding/finishing/painting is a similar experience to the standard wood we deal with all the time. Does anyone have experience building with MDF core plywood? I wonder how much the difference in strength would affect a build.
(btw, no formaldehyde in the MDF i'm trying out so should be safe to cut with a laser)
