awesome video! I see you have the AMS. Whe printing PETG, you should try to use PLA for support (or support interface to minimize waste). PLA and PETG does not stick, so youll get super clean prints where the support meets the print. Z distance = 0.
Thanks. Yes I know about it but never printed this way (even have support filament that came with the printer). I rarely use AMS to combine the filaments as the print process jumps from hours to days lol! Like I did here, I rather split model in separate color parts and print faster: ruclips.net/user/shortsk-Rw3RSZkEM ... but thanks for input planning to print some in future with PVA support filament :)
Cool project! I can offer you some tips for improvements to test, if you like: You don't need to print the whole part in 100% infill. CNC Kitchen published a test on which parameters are more impactful on the strength of the part and tldr, the perimeters are much more important for strength. Maybe try printing with 6 walls and top/bottom shells and 30% infill. You will save on material, weight and print-time aswell. Made with Layers recently also published a video on infill patterns and the best allrounder there was cubic, so I would recommend that. Also, you could try another type of filament, ABS GF. It is infused with glasfiber which makes it stiffer aswell as lighter. you could save a little more weight there and maybe even go down on the number of perimeters while printing. For your issues with the supports with PA, you could take advantage of your AMS and use another filament as the support interface, one that doesn't stick too much to PA. ASA is supposed to be a good choice here, though I personally haven't tested that. PA itself has a really good layer adhesion, which makes removing supports harder.
thanks will check it out! Not necessarily looking for more stiffness. The PC is very strong, but still cracks too easy on impact. When I compare the printed wheels to the originals, I am able to push and deform the originals a bit by hand. So I need to print it in something more elastic which would be the PA, TPU is too soft. I know about the option to print the support in different filament and might try it with PVA but just don't print that way as that takes soo much extra time.
true!.. but also I found out it cracks really easily on inpact, the PA is now my favorite.. just have to print supports from other material which takes forever :/
yes I actually did few prints like this.. the surfaces that I wanted to glue together were never exactly flat, probably due to plate not being perfectly flat or warping during the print.. so I gave up on that idea
the bambu lab Aero fillament might be worth trying...
wouldn't it crack even easier when it's low density filament?
@@therealfazee ruclips.net/video/7AVTINNAqVI/видео.htmlsi=zhZ-M3fsvUiyhj7a asa should be very tough...
Nice work.
Thanks!

yeah there is also Support for PA/PET from Bambu
PC is really strong and affordable

@@therealfazee Yeah toughness is probably the priority in your application.
Have you considered modelling and printing an insert to glue or screw over the 'ugly' outer face to hide it?
