Hi all,
Long time community member here. Very sad to recently find out about the massive loss of information from the banning of fosscad, but before this I was trying to do some research and am hoping to get some information here if anyone has it on some of the newer filaments that I have seen recently and if any are worth picking up. I am just polishing off the last of my PAHT-CF and Polymaker nylon-GF spools, which have been incredible for my projects, and I’ve seen that polymaker has been releasing a lot of new filaments under the fiberon line and rebranding old ones. Are there any of these that are worth checking out and has anyone been done any up to date experimentation with some of these newer blends?
Thanks all, RIP r/fosscad
For the most part, if you dont need your hand held, I would steer clear from polymakers PA/PET offerings. They are geared towards printability (think open-air printers) instead of performance.
Sirayatech on the other hand, has amazing performance for very low price. I have tested a fair bit of PPA-CF (at 62$/kg and 45$/kg if you print with .5mm or larger nozzle, they have a special batch) and have been very happy. However, latest this month they are releasing PPA-gf at 45$/kg and I will have some in for testing soon.
polymaker pet-cf is fine. the differences between polymaker and bambu petcf are diminished returns
If you think it’s diminishing returns to go from PM pet-cf to bambu lab pet-cf, why would you choose it over Sirayatech, which is more performant than PMs offering AND much cheaper? You can get PET-CF from ST for 37-34$/kg vs 25$/.5KG (50$/kg).

PM comes in last in every test except for Impact Resistance (which is a fail) and price (because they used the 3kg price.
The PM offering was designed with printability over performance and comes in last place in creep, 3-point bending resistance, tensile, layer adhesion (enclosed)
Where is ST Pet-cf is the cheapest tested and basically always comes in either 2nd or tied for 2nd.
