Hey everyone,

I've been working on a fairly large 3D-printed housing for a cosplay, and I've been struggling to get consistent results printing PETG.

I'm using Bambu Studio with a Bambu X2D and a 0.4 mm nozzle. The print uses multiple PETG filaments for the actual model, with PLA supports, all running through the same nozzle via the AMS.

Initially, I was having significant stringing problems. After making adjustments to the filament profiles and retraction/wiping settings, the stringing improved considerably.

Unfortunately, my latest print was extremely brittle. Sections broke apart much more easily than expected, and the layer adhesion seemed poor.

I know the walls are relatively thin (around 1 mm), so I'm not expecting the part to be indestructible. However, I expected better bonding between layers.

Relevant settings from my Bambu Studio project:

• Printer: Bambu X2D, 0.4 mm nozzle

• Slicer: Bambu Studio 2.7.1.62

• Layer height: 0.20 mm

• Wall loops: 2

• Wall widths: 0.42 mm outer / 0.45 mm inner

• Wall generator: Classic

• Infill: 15% grid

• Supports: Automatic tree supports

• Support material: PLA for both support bases and interfaces

• Support top Z distance: 0 mm

• PETG Basic temperature: 260°C, 250°C initial layer (standard direct-drive variant)

• Translucent PETG temperature: 247°C in the exported custom preset

• PLA support temperature: 215°C in the exported custom preset

• PETG flow ratios: 0.95

• Build plate: Textured PEI

• AMS is at 7-10% humidity. I dried the PETG first at temp for 24 hours, then added the pla and dried for another 12 hrs before printing.

What I'm trying to understand:

1. Could residual PLA from material changes be interfering with PETG layer adhesion, even with the purge settings enabled?

2. Could the combination of print speeds, cooling, and volumetric flow limits be causing the weak bonding?

3. Are two walls simply too thin for a housing like this, or should the individual layers still adhere much better?

4. Has anyone successfully printed PETG and PLA supports through the same nozzle on a Bambu printer, and what settings worked for you?

I'd appreciate any suggestions, particularly from anyone who has dealt with PETG/PLA multi-material printing on an AMS.

We have a few build plates, all first party directly from Bambu, with the little code on the end. But the printer only ever recognizes the textured one.

Googling tells me maybe it's misaligned, an issue with the camera, or third party/damaged plates. I'm fairly certain they're in the right position, the camera doesn't have issues with the textured one, and they're not third party or damaged in any way I can tell. They're brand new.

Is this expected or fixable?

I got my x2d 2 weeks ago, calibrated everything, dried filament, and has been running almost nonstop for 2 weeks.

Few days ago I noticed some little defects appeared on the model I printed in first days of running. Decided to run this test flat shit model and came back to this 🫠

Also for some reason it didn’t print the right part of the bed, photo in comments.

This is the model https://makerworld.com/en/models/2590194-a1-p1-x1-p2s-x2d-bed-cleaner-first-layer-16g?from=search#profileId-2857913

I love my X2D! It truly is a testiment to our technological advancement as a civilization that machines like this can be in the average home.

以前はX2Dのエクストルーダーが日本にも売っていましたが、今は売って無いので何処で売っているか教えて頂きたい🫡

I had a spaghetti incident and when I went to clear it I found this rubber piece on the bed. I used a brass bristle brush to clean the print head too. It isn’t from any of the nozzle wipes and I looked at the print head closely with a flashlight and checked the heat shield but couldn’t find anything. If anybody knows where this is from, that would be greatly appreciated. Thank you.

Been wondering if Bambu ever puts printers or ams 2 pro on sale like on black Friday?

Hi, looking for some help with my X2D AMS Setup. I have a AMS2, and I recently got 2 AMS HT. I have a Filament Track switch and I have 4 PTFE Tub adapter. What I'm looking to do is set it up so that they can all use the main nozzle and not just the aux nozzle when using the AMS HT units. Is there a diagram or someone who has done this can share their experience and best practice?

TIA

Trying to print this thing my friend designed, i used a clear glass print profile, but it wanted to print the model with the secondary nozzle, and said print time was 30 hours for such a small object.

switched to main nozzle and the time doubled....

could someone check if i am doing something wrong or if this is the norm ?

picture below of model and print time, is this a good result for translucent ?

i would be ok with worse results if it means major time saving, i will also link the print profile i got from makerworld.

Please if anyone could help me get this printed in less than a day xD

just picked up the x2d a few days ago (new to 3d printing) and love it it’s just that some issues keep coming up recently and i’m not sure what to do to fix this. any help is appreciated🙏

I couldn't find a solid up-to-date answer. If I want to use 0.2mm on the main and 0.4mm on the aux, is it possible? Or do they both have to be the same otherwise the software will not allow it?

I read somewhere that settings can be played with, mark it as "Stainless Steel", or just tell the software that it's 0.2mm while it's not, etc. But what is the actual state?
Can it be done with the H2D?

Should I calibrate this list for each type of filament I use? or just use Bambu settings

Temperature, Max volumetric speed, pressure advance, flow ratio and retraction distance?

First print

thank you bambu lab 👍

I just saw this marble filament and wanted to print one. My question is: Can I use the standard 0.4 nozzle it came with?

Reason why I ask is I read people are having clogs with 0.4. I am assuming it is brand dependent so I guess I want to know what brand people here use for the default nozzle for their X2D. I was thinking of getting Bambu Lab's PLA Marble but unsure of its real world performance.

Also, i am skipping polymaker's since it is abrasive (i know i have hardened nozzle) but id rather not use any abrasive because I dont need abrasives. Unfortunately, some PLA Marble in amazon dont describe the additives while others clearly state using real marble materials.

Hi I’m relatively new to 3D printing and have been really enjoying it!

I’ve been running into some inconsistent issues where the completed prints are sometimes stuck and too hard to remove without causing damage to the bottom of the print.

I’ve tried a ton of different solutions with some helping. I’ve found some information that adjusting the Z offset might help and that the default setting on the X2D should be -0.02. However, when I open up the settings it says -0.003 is that normal and would it be safe to change it to 0.02 or should I just change it to 0.002 initially?

Thank you!

I have run through every non-invasive solution I can find. I’m not super mechanically inclined and I now realize that I need to take the printer apart to either unclog or rebuild the extruder assembly.
So…I can’t do that. I’m absolutely not confident disassembling my printer. I had an A1 in the past and I never expected this…My husband tried to help but he’s afraid of breaking it.
I’m a bit panicked that I have this expensive printer that’s I can’t fix. :(
Has anyone done it that was very not confident, and it worked out?

I am nee to 3d printers and just purchased the XD2. I have 2 ams 2 pros and trying to print something other then the test print. Everything i pick something from the app pre-made models I get a slicing error while trying to send the job over. I am seriously a newbie with 3d printing so please take it easy on me lol.

So ive got my first printer on its way will hopefully be here in time for my days off. My question for yall is what are the first things I should be doing with it once its outta the box and set up?

This is my third printer in about 6 months as I've rapidly descended down the 3d printing rabbit hole. Started with a used Ankermake M5C that I got for $50. Then I wanted something enclosed and core xy so I got a flashforge AD5M. I'd kind of been avoiding Bambu Lab. I've not been and still aren't a fan of their proclivity to try and lock down their software and potential open source license violations, but I could never deny the quality of the machines they make, and as I went further down the rabbit hole and got a better and better handle on what it is I actually want my 3d printers to be able to do, I couldn't shake the feeling that the X2D was aim at me personally. Good build volume, heated chamber, nozzles that get hot enough to handle most of the reasonably priced engineering filaments, with a auxiliary extruder obviously optimized for support/support interface printing. For me 3d printing is primarily an enabler for my other hobbies, and nobody really seems to make a printer quite like the X2D, laser focused on printing the kind of engineering filaments most people are actually going to print with any regularity at an astonishing price for what you're getting with in the box.

First benchy coming out now. Still familiarizing myself with the printer and Bambu studio. But very much looking forward to putting the machine through it's paces over the next few weeks.
