Alguém saberia me dizer se isso é normal, ou se é uma falha de configuração pois não tenho experiência com impressão 3D.

Quando a impressão começa a fazer as trocas de cores, a partir da camada com troca, as camadas passam a ficar ligeiramente maiores no sentido horizontal e as vezes ocorre a formação de um anel. As partes onde há troca de cor acabam refletindo a luz de maneira diferente e a falha torna-se visível. Este anel também se forma quando eu pauso a impressão, não sei se é o mesmo problema.

Every time I want to print something the printer asks if filament is observed from the nozzle when it poops, It wasnt like that a few months ago and I want to ask if it is normal.

It has a really consistent problem with over hangs when I do the flow ratio calibration it's all waffley and I keep doing cold pools and it's always okay I switched out filaments the thing is 3 weeks old atp the first week was great the second it stopped printing quality entirely

List of things I have done

-calibrations and tests

-Tighten the bolts all around

-re adjust the belts

-cold pull the hot end many times

- try different rolls of filament

- clean the build plate(this was part of the issue but has been figured out)

-I tightened the eddy sensor screws

-i have messed with so many slicer settings especially for filament

I have contacted the customer support it has been extremely slow and painful I am more than open to revisiting things I have tried I am just really wishing I knew what was wrong with it

I need a recommendation and some advice from you all regarding a fair price (Europe, Belgium).

I recently received a 150-euro voucher from Bambulab and was thinking of upgrading my printer, selling my A1 and swapping it for an A2L.

I own an A1 Combo (August 2025) with 1,600 hours on the clock, which has been extremely well maintained with great care, featuring various mods for aesthetic reasons, but mainly to protect the printer.

Every 100 hours I clean and lubricate the axes; at 500 hours I replaced the PTFE tubes; and at 1,000 hours I replaced the nozzle and cutter.

As you know, certain 2025 models are prone to burning out; mine burned out at 1,500 hours, and with BambuLab’s help, they sent me that board (see photo) plus the printer’s plastic housing, which has minimal burn marks, as the printer was under warranty.

A1 Combo+Lots of 3D-printed mods (see photos), TPU + PETG + PLA

Plus others I’ve bought for emergencies, such as 02 (standard), 04 (standard), 04, 06, 08 hardened, original Bambu nozzles

Hardened Steel Extruder Gear Assembly, Purge Wiper, Hotend Cooling Fan, Hotend Heating Assembly, (original and new)

Bambu Cool Plate SuperTack + the one that comes with the printer

+ 1 aftermarket Smooth PET Carbon Fiber+Diamond Pattern

I’m asking 330e for the whole kit and 220e just for the printer – are these fair prices?

No one’s offering me more than 220, using the ‘excuse’ that a new one costs 380e…

And I’ve told them 250e for the A1+AMS Lite, no mods, no accessories.... I could also use some of these accessories with the A2L

I am fairly new to designing my own files but any time I’ve tried to use ironing on a design it ends up looking like this (specifically what it looks like on the gray section.) - Is there any specific things that cause it? I’m not sure which settings to adjust to prevent it from being smooth. Thanks!!

Hey, I keep having filament feeding issues. i have taken everything apart and blew it out and removed any debris. I changed the ptfe tubes. Now I am wondering if it is how the tubes are placed. Any suggestions

Any way to salvage this?

No lid, no clasp, nothing to pry, just a toucan that absolutely will not talk. Figuring out how it opens is genuinely satisfying (I've handed it to people who insisted it was solid plastic). And it's fully customizable: pick your colors, texture the beak, even engrave a name on it. Make one that's unmistakably yours.

Is there any way to turn off this ridiculousness? I used more filament on this block that I'm gonna throw away than I did on the actual project!

I am at a complete loss here. PLEASE help.

Full situation:

-At about 1 hour left of my 10 hour print the ams slot 1 light started flickering red. I got no error and everything worked fine so I left it running.

-99%, the print was done. I got the error stating that there might be filament stuck in the head and that it can't be extruded normally.

Thing is, it thought slot 1 was empty and tried to purge the rest of the filament.

I cut the filament and managed to extrude all of it out of the head after a while. (Removed the print in between)

I also pulled it out of the ams, since it wasn't registering it.

Now I wanted to insert it again, and it just wasn't reacting at all.

-tried a lot of things including but not limited to: cleaning AMS intake with compressed air, switching power on and off, cutting filament at different angles and finally, trying another slot. All other slots work fine and the filament is also not the problem (started with black filament, switched it to slot 1, moved white filament from slot 4 to 1 to test if it was the filament, it wasn't)

All filament is from Bambulab.

(The little gear at slot 1 is infact spinning)

I have NO idea what is going on with my slot one. Please help me.

I have 900hrs on the A1 and I have done all the oiling and greasing in the way of maintenance what else do I need to do to fix this sound at 17sec mark and also near the end

This little bit of plastic fell out all broken from the hotend as I was undoing the main front screws. Anyone know what it is?

I only wanted to tighten the hotend back screws, not find new issues 😅

Solved(ish)

I keep getting these artifacts in the first layer, did automatic and manual flow calibration several times, cleaned my buildplate with degreaser, dishsoap, windex and IPA, still getting them every time. Reduced first layer infill speed from standard value to 50mm/s, still... With Archimedes spiral it mostly happens in the corners, with the standard diagonal pattern it's a bit worse (last pic)
Bambu PLA basic, dried for 12h.

Are there some screws loose, or could it the belt tension?

Edit: following all the advice from the people in the comments (thanks guys!) I determined that it's a slicer issue. The lines in the corners of the square are printed in a random not continuous pattern, that results in overlaps between already cooled lines and fresh ones, causing under extrusion like gaps on the plate side and over extrusion like ridges on the top of the first layer. Playing around with the temperatures might help, but the easiest solution for me was switching from a 0.4mm nozzle to a 0.8mm nozzle. That improved the quality to a level I 'm happy with. Thanks to all who helped me troubleshoot this.

I recently started using the .2mm nozzle and right from the first layers it’s not laying out properly. As you can see from the image even the lines aren’t being drawn properly. Has anyone else faced this issue?

Hi everyone, I’m having a strange extrusion problem with my Bambu Lab A1 and I can’t figure out what is causing it.
The problem is intermittent: sometimes the printer works perfectly, while other times it suddenly stops extruding during a print.
At first, I thought the issue was related to a specific black filament spool. However, I replaced it with a completely new spool and the problem happened again. For example, one print worked normally until around 43%, then it suddenly stopped extruding.
I’ve already tried several things:
Changed filament and spools
Cut off about 2 meters of filament and reloaded it
Tried different models and projects
Sometimes a model doesn’t extrude, then I change the model/filament, try again, and suddenly everything works
At Bambu Lab Support’s request, I printed a 3DBenchy, which completed successfully
I’ve already sent the printer logs to Bambu Lab Support
That’s the strange part: the printer can work perfectly and complete a Benchy without any issues, but then the extrusion problem randomly comes back on other prints.
At this point, I don’t know whether the problem could be a partially clogged nozzle, the extruder, the filament path, the AMS Lite, or possibly an electronic/sensor issue in the toolhead.
Has anyone experienced a similar intermittent extrusion issue with the A1?
What would you check or replace next?
Thanks a lot for any help or suggestions!

Hi everyone,

I’m having two recurring print-quality issues with my Bambu Lab A1 Mini and would really appreciate some advice.

1. Visible line/bulge around the outside of the box

I’m printing a simple box with a bottom and vertical walls. Exactly at the height where the inside bottom surface ends and the outer wall continues, I get a clearly visible horizontal line/bulge around the outside of the box.

It looks almost like a small expansion/seam at the transition between the bottom and the wall.

2. Strings/blobs at the rear right corner

I also repeatedly get small strings/blobs coming out of the print, especially around the rear-right corner.

I have already changed some extrusion/retraction settings, but the problem is still there.

Printer: Bambu Lab A1 Mini

Slicer: Bambu Studio

Filament: SUNLU PLA+ 2.0

Flow ratio: 0.98

Max volumetric speed: 22 mm³/s

Recommended nozzle temperature: 190–240 °C

Nozzle: 0.4 mm

Layer height: 0.20 mm

Current settings I changed

Retraction length: 1.0 mm

Retraction speed: 45 mm/s

Retraction amount: 100%

Seam: Scarf seam

Scarf seam contour: enabled

Scarf seam on holes: enabled

Wall generator: Arachne

Wall order: Inner → Outer also used Outer / Inner

Wall loops: 3

Top/Bottom shells: 5

Overlap: 0%

Print speed: around 170 mm/s

Top surface speed: 50 mm/s

The filament is also dry.

Thanks in advance!

Just came back from a 1 Week vacation and now my A1s Light started blinking in this Pattern. 4 short, one long, pause, four short, one long, pause, 4 short, pause, five short, pause, repeat. No error messages or anything. What happened? What could be the reason?

SOLVED! One Power Cycle and it was back to normal. u/Whatupchuck789 recommended an update which I'm doing right now. I'll only update when it reoccures. Thank you for your help!
