A relatively seasoned 3D printer, with years of Ender 3 experience and have been loving the X1C since upgrading about a year ago. I’ve had great success ‘out-of-the-box’ with PLA, PETG, and TPU.
Then I decided I wanted to print a plane.
I started with the Bambu ASA Aero, thinking it would be an optimal combination of strength and lightweight. After countless fails (okay, about a dozen with that filament, I decided to try my luck with Overture Air PLA. I saw comments from folks saying ‘prints as easy as PLA’ (and given that it’s “pre-foamed” - I guess it’s pretty close to ‘standard PLA’ in characteristics).
I’m now a good handful of fails into Air PLA, as well. I’ve tried (minor) tweaks to both filament and print profile settings (temp, bed temp, print speed) - and even using different print surfaces: textured PEI is my goto, but I also tried the Engineering (smooth) plate.
I haven’t brought myself to applying glue stick to the textured PEI plate - perhaps that will be the fix?
Aside from any additional #ProTips from folks who are successfully printing this filament - one clarifying question for @skloter: Is your “Retraction Length” setting above actually .5mm? Currently my retraction length is set to .8mm (based on stock Bambu PLA filament profile). A change to .5mm seems reasonable - but a change all the way to 5mm seems extreme.
Gonna try it with .5mm and see how it goes. The failure I’m having, in EVERY case, is the print separating from the build surface, resulting is spaghetti failure.
So on both the textured plate and the engineering plate? Also with glue on the engineering plate?
When I have a challenging print, I always give my plates a clean with warm water and dishwashing liquid (and a clean dishwashing brush with a lot of elbow grease for the textured plate). Smooth plates then receive a few lines of PVA glue stick which I then swirl around with a moist/wet paper towel until a nice water-PVA film has formed to dry to a thin adhesive/release film.
Works every time (unless I did not take sufficient care with drying the filament and get early curling).
I am not a Bambu owner, using a Flashforge Adventurer 5M Pro that seems to have similar characteristics. I thought the 5mm was a typo at first but tried it. That along with the adjusted flow rates has resulted in really good prints now. Thanks for sharing!
For others:
There are several other settings I changed as well, based on the guidelines from 3dlabprint for the plane parts I am printing. Those seem to be targeted to bed slingers, which I had dialed in before. For a more modern core-XY, I’d follow the model supplier suggestions and maybe slow it down? Do the retraction and flow adjustments and see if that improves results. I’m printing at 210C, bed at 60C, textured PEI plate with the Flashforge bed adhesion stuff applied, 15mm brim.
I know this might be a little bit late, but I just printed a semi-wing using that filament in a X1C. I loaded the filament in the external slot and set it as an Overture PLA. I used Bambu Lab’s Bambu Cool Plate Super Tack plate and the print came out flawlessly at the very first attempt.
