I’m new to 3D printing. My 1st plate was perfect. 2nd plate very minor issue. I believe we can fix. I’m printing plate 5, and it looks like I should bail on the print and start again. Why does this happen? Bambu Lab doesn’t have the colours I want, so I went with SUNLU from amazon ships quickly too but maybe I’d be better waiting on Bambu Lab. This is 25% finished and I saw this.

I would cancel that print. It can happen for a variety of reasons. I have printed 2 chairs now all 100% with Sunlu PETG so I don’t think that is your issue. It could be wet. Or there could be a setting issue if you are not using the right filament settings.

Thanks for your quick answer yesterday. I’m learning a great deal about 3D printing with the project. I will reprint this one. We are going to our brand new filament and try again.

I agree with NWCC. I used SUNLU PETG for my chair and had no issues. I use SUNLU almost exclusively for the quality and price. I typically only buy Bambu filament when I have gift cards from MakerWorld. It’s a fine filament and never had issues. It’s just more expensive than other brands. I used GEEETECH brand for the TPU pieces. Be sure to dry your TPU. Otherwise it will be a stringy mess. Happy printing.
Also, what is your infill pattern? It kind of looks like grid, but I can’t tell for sure. Sometimes grid can cause your nozzle to drag. Gyroid is a better option.

Long time printer here. That issue is not wet filament. It is from the build plate not being clean. Likely oils from your skin contacting the plate when removing a previous print causing your supports to fail.
It is an easy fix though. Take the plate and clean it with hot water and dawn dish soap. This removes all oils from the plate and brings back adhesion.
Another tip. By default the supports in these prints are too close to the actual print and you will have issues removing them on some parts. To fix this, before printing go to Bambi studio with the file open. Go to the support settings and change top z distance from .2 to .28. Also change top interface layers from 1 to 3(anlso in support tab) Also change x/y distance from .35 to .38. This gives a little more distance between the supports and the print making support removal easier. The top interface layer will add 2 more layers on top of the supports and will give a better finish.

This is all really helpful. I’m following all your advice and trying again. Thanks everyone
Thanks everyone for all the input it is all very helpful. Our nozzle had 217 hours on it and was clogged with flimament. We are thinking that this is maybe the root of our problem. Going to replace it. Also, follow all your recommendations too. We are really new at this! 217 hours and counting.
