  • Hey Ill give your paper a read, thanks for your work. Icant stress enough how important is the work of the devs to the community. I think I once saw an even harder TPU, but that is probably another dead end. I agree that the artistic filaments are a dead end as well, but not everything is what it seems, ie I can’t find much concrete data on that CF PLA from Creality but according to some it has better layer adhesion than some non CF PLAs. And dr Gaspar tested the Tinmorry CF PETG that also had better later adhesion than vanilla.


  • This will be a hot take but I think the community is too conservative with materials. I understand that printed bang sticks are inherently dangerous and it’s best to be on the safe side, but there was a guy on reddit who printed launchers out of ASA only and got shit for that despite having working proofs. There even was a guy who posted a beautiful Urutau made from Creality Hyper PLA-CF and claimed over 100 rounds without signs of damage. OG FGC-9 readme calls for plain PLA. That is not something that an average Joe should do, but experiments could lead us to material independent designs. And it would be a good thing, Homeland security can’t put everyone who orders any type of filament from Amazon on their watch list.


  • Traditional PA6-CF is still arguably a better choice as it has higher impact resistance and it’s cheaper. Dr Gaspar has great videos and is the best resource available on youtube, but you have to take some of his results with a grain of salt as he used to have constant troubles with layer adhesion in older videos when he was printing with open printers. And he doesn’t run all tests across the temperature range which sometimes might change the properties, uses very small sample sizes and sometimes doesn’t follow up on weird outliers.
