Also, the ABS-GF does a good job of resisting warping. I ran a small mountain bike tool yesterday with it, and while I would ordinarily have the door shut for the ABS, I accidentally left the door of my P1S wide open, on a print that would ordinarily have warped badly. The additional rigidity of the -GF apparently meant that the warping was much less of an issue.
I just did this on my P1S, hardened nozzle. The new Bambu PA6-GF for the dark parts, the ABS-GF for the body. I was very pleased with how well the printer did both of them, and I would say the hardened nozzle is a must-have for doing these materials.
Attached FileIt actually sounds really good, much better than the PLA Silk one I printed, and as a bonus, I don't think my car can get hot enough in the summer to unmake the new one, unlike the PLA instrument.
