This print is so frustrating. 50% of the time it comes out perfectly; 50% of the time it’s a hot mess.

Are the built in calibration tools in Bambu Studio the best place to create filament profiles? I used the generic PETG-HF profile for this and it has flaws, stringing and doesn’t seem to have good strength.

(The filament is Sunlu High Speed Matte and it was thoroughly dried before use and run directly from the filament dryer.)

Are there any model makers who could advise me on painting this thermal detonator model, please? Something like a dry wash to give it more of an aged look perhaps? I haven’t made models since I was a child so I’ll have to buy everything I need. Any advice would be wonderful. It is screwed together, not glued, so it’s easy to take apart for painting.

I printed an adapter for the Sunlu mini spools but I had about 10 stuck filament warnings on a 2-hour print. The angle of the filament seems really awkward. I don’t know whether it’s the adapter at fault or whether I got a badly-wound spool but I kept having to untangle it.

I’ve tried to print this part for a toothbrush stand twice. The first time it detached from the (clean) plate within a few layers so I added a 10mm brim and printed at 50% speed; that time the bottom layers stuck to the plate but it broke off further up. I used PETG filament that was dried in a filament dryer just before use.

Are there any supports I could add to stop it from breaking during printing? Also would it be beneficial to switch on vase mode?

My son wants to print this but I don’t have any purple filament. PETG is cheaper to buy than PLA but am I right that it won’t print properly along with the yellow PLA that I already have?

EDIT: SOLVED

I had a failed print with blobs of filament that I had to cancel on the second layer so I tried a different quick print that had printed successfully before. The printer made a lot of noise and the print quality is terrible.

I had already checked the screws in the print head and run a full calibration; bed was thoroughly clean etc. It’s the noise that worries me as it sounds like something is going to break. Could it be something loose inside the print head causing issues?

Can anyone please help me guesstimate how much filament is left?
