I was looking to stock up on PPS, PPA, PET, and other PA during bambus Black Friday sale. I noticed some other people talking about siraya tech PPA which is pretty cheap compared to bambu.
What is your favorite price/performance brands for some of the more advanced filament?
Siraya Tech PPA-CF is my current “go to” for parts that need more capability than I can get from PLA+ or PCTG. Bambu PPA-CF edges out Siraya in most (maybe all) performance metrics, but for me that’s not enough to justify 2X the cost (at sale prices, 3X normally).
Lookin to the TDS, BambuLab PPA-CF beats ST PPA-CF. But it’s hard to compare the values directly, because BambuLab separates the values of Z and XY and SirayaTech not. Anyway it still tough PPA-CF material and ~2x cheaper. I’d probably pull the trigger.
Currently my go tos are ST ppa-cf for important parts, polymaker pet-cf for nonload bearing parts(where I would traditionally use pla+ in some color, I use pet if I wanted the ash black color, or if I want it to last longer) and polymaker pps-cf for suppressors
