How do we feel about PETG-GF? (forum.guncadindex.com)

Someone recently turned me on to a new weird PETG-GF that is supposed to be very impact resistant and very affordable. I'm always interested in new materials, especially those that are cheap and easy to print in.

I use this "UFA compliant compact striker fired artillery boi" platform for material tests. If it's built well in PLA+, they will take a solid diet of high velocity 22lr with a standard printed breech.

This has been the best one of these I have built so far. I have ran shorts, standard velocity, high velocity, stingers, and interceptors. Extracts flawlessly. No signs of wear at all.

I'll take it out and run the hell out of it within the next couple of weeks.

Some asa/abs cf/gf is similar in that it has better layer adhesion and impact than non filled.

Do you remember the brands by any chance? I'd love to give something like that a try. I like PLA+ but I really don't like its thermal properties, and some kind of ABS that behaves that way seems like it might be just what the doctor ordered, especially since ABS is usually like half the price of nylon.

I bought a spool of ABS+ that on paper should perform similarly, but I haven't gotten a chance to try it yet and I like the GF/CF external finish.
