I'm using some uniquely ugly drivers in A-pillars - right where they'll be seen:
So I 3D printed some covers, and I did a run at a "normal" resolution, but I used PLA, which has a melting point below 200 degrees. After extruding it might be somewhat higher, but I'm not sure how much higher.
Even getting them this far, I'll need to do some bodywork to them, since they aren't perfectly smooth. So technically that will bolster the structure, although I'm not planning to do more than a normal bodywork thickness (thinness, I should say).
I do own some black ASA, which I bought specifically for higher heat needs. I think I'm only hedging because the two rings took about 10 hours on "normal" (not even "fine"), and the four square panels also took about 10 hours.
I should just bite the bullet and run them on ASA, but I am curious-
Has anyone used PLA for interior parts? Will it *really* run the risk of melting? These are not structural, just decorative overlays ...On the other hand, there will be magnets CA glued to the back in those recesses...
Just curious how much of an issue this really is.
Bear in mind I'm in Buffalo NY, so it only gets into the 90s for maybe a month at the most, each August. It's not Arizona, here.
90% sure I'm going to run these in ASA over the next couple days and go from there, but curious if anyone's seen softening.
