I haven't used ASA. I have done one firewall in PLA and it did melt. PETG has worked just fine for me.
After I asked, i did a lot of comparisons and really, PETG is the one that pencils out the best. Though ABS and ASA can print a little faster, like @Piotrsko mentioned, not so great for the breathing air. Ooooooo. As far as “strength”, it depends on what the application is and each have their strengths and weaknesses. But for us crazy foamy guys, PETG is more than adequate, and 3) we don’t need to breath any more toxic fumes than we already have. So thankfully my blind choice was the right choice since I stocked up on a few rolls of PETG. See? It is true! Even a blind nut finds a squirrel from time to time. This printer is pretty much meant for industry so its capabilities far exceed what i need for the moment.

Here is a mock-up of the giant duck’s engine nacelle. The front cowling is a first edition. I made it way to thick and heavy so i went back to the drawing board and made a way cooler one that i will post when its done printing.

Here is the updated cowling. I made some adjustments to the printer so hopefully the next one will have a smoother leading edge. The intake is functional and will direct airflow over the ESC heatsink. The main cowling will direct air through the mount and around the ESC. I will probably put a vent or two at the rear of the boom to allow flow through. Most likely they will look similar to the ones on the P-38 but with the opening facing the rear. Like my signature says, this project is fluid until the glue cools, so please please folks, SUGGESTION, I’ll take‘em!!!

Sweet! It is coming together……..

It will look great in the air!(y)
I foresee many moons passing before that glorious day. This all started with a “hey it’s foam board. Let’s build a giant one. It’ll be easy, dur-hur…” and so far has progressed into a life lesson degree in Mechanical Engineering with minors in Aeronautics and Electrical engineering. All kinds of new gadgets and gizmos. 3D printer. I even made a big enough mess my wife told me to take over the spare room. I have a legit hanger now! Besides, who likes friends? I just make mine sleep on the couch like we’re 12 again. Maybe that’s why i only have 1🤔…. Anyway, the printer is a game changer though, and has opened the hanger bay to the beautiful abyss of my imagination. Thankfully that “abyss” is relatively shallow and incredibly well lit. 🤣

I hemmed, I hawed. I pondered the meaning of life. Finally there was no ther solution than to reprint in a different orientation. The first (actually second) version is the white one and it was printed face down in PETG on the PEI plate. It had all the proper support and such but that leading edge is just garbage. so i decided to try it in ASA. i have never printed ASA so I tried a calibration cube and absolutely nailed it and at ludicrous speed. So I sliced the file, switched to the PC plate, and sent her to the queen bee creator aaaannd… VOILÁ!!! Her she is!
