Sorry if this is a noob question, I’ve been printing a lot, I am now on my 4th bambu printer (X1, A1, A1 mini and now H2S) but I’ve always kind of been printing with defaults relying on the machine to get it right. Most of my models have been quite simple without the need of too much filament change/intertwining.
But now, I have to print something in translucent PETG and the only other PETG in black that I have is PETG-HF. See below. The filaments should be pretty dry, I am running the dryer for another 12 hours today and will give it another shot tomorrow but this is a longer print and can get expensive, so I am looking for some expert advice as to what is causing this to happen. When I got the print out this morning one of the hotends had some stringing on the nozzle, not sure if that caused it.
If anyone has any ideas, I would appreciate it and will report back with my next trial tomorrow. Could it be that the HF is not really compatible with the Translucent? Or they have different speed settings and cause that problem? Is there anything that I absolutely have to do to make sure this print comes out smooth? Happy to make it last 24 hours instead of 8 if quality is good enough. But since this is also a model I want to share and make available on makerworld, having a decent speed/quality ration would be nice.
thank you and I appreciate your time and advice. noob jokes are welcomed.
You’re printing something that is very hard to prevent from stringing even if you’re printing single nozzle. It requires lots of experiments and trial and errors and nobody can guarantee that you would get perfect results.
thanks! not looking for a guarantee, I have realized that and came here for some advice. I already got some PMs, looks like “dry” isn’t quite what I had in mind. I am drying everything again very well and will give it another go tomorrow. I appreciate you taking the time to respond, I am hoping that with some good advice I can just speed up that “trial and error” on my end. that’s all I expect here.
I would suggest that the black filament is not calibrated or is wet. It is chunks of black ooze that are impregnated all over, and the orange seems mostly tidy.
I dont know if relevant to PETG + PETGHF but when using two dissimilar materials you would want to max purge volume as far as it goes. IDK if these are dissimilar enough to warrant the same precaution.
yeah, looks like it. I dried them both yesterday and running a new print, so far I see a huge improvement, hopefully it stays that way. I am concerned about the nozzles getting a bit dirty with strings and impacting the quality along the print job, I’ll try to keep an eye on that too.
came out great in the end, just had to dry them all very well and switch to a more “quality” focused print profile, one of the bambu defaults. simple task with dry filaments. thanks all for your help!
