These in-house developed print profiles are an excellent starting point for printing with 3D-Fuel Pro PCTG. If you find a better setting for your 3D printer with our materials, please let us know, and we can look into revising and improving our stock profiles with your feedback.
Bambu Lab 3D Printers
We recommend printing with the Textured PEI print surface for the best first-layer results and print adhesion. If you use Smooth PEI, the printed parts will stick too well and may damage your print surface.

Regarding the 0.2mm profiles, Bambu Studio doesn't allow PCTG as a material base type for 0.2mm nozzles. So the 0.2mm nozzle profile is identified as a PETG base material.
It will appear in your filament list as 3D-Fuel PETG Pro PCTG 0-2mm nozzle.
The Bambu profiles were updated on 5-21-25.

We also recommend using an outer wall print speed of 50mm/s for the best, most consistent surface finish.
Prusa 3D Printers
We recommend printing with a Textured or Satin PEI print surface for the best first-layer results and print adhesion. If you use Smooth PEI, the printed parts will stick too well and may damage your print surface.

what print surface do you recommend for this I have 2 beds with missing chunks now I'm printing on painters tape now haha
I am looking for print profiles for the Prusa line of printers, particularly Prusa Slicer.
Jon Fernandez,
I recommend the Bambu Lab Engineering print surface. Or, if you use PEI, make sure to use glue stick as a release agent otherwise it will stick too well.
ConnorB,
Which Prusa printer are you looking for a profile? We may be able to build a profile for a specific printer.
Otherwise, I recommend that you start with a PETG profile and set the hotend temp to 260C and dial it in from there.
I use the satin sheet (https://www.prusa3d.com/en/product/xl-satin-powder-coated-steel-sheet/) for anything not PLA essentially precisely because Prusa says "don't or you can destroy the PEI sheet". I have the MK3S+ and primarily use the Prusa XL (the one with the boogery nozzle: https://www.amazon.com/Diamondback-Nozzles-Compatible-Polycrystalline-Extrusion/dp/B09X61NG5S).
PETG and PCTG stick nicely to the satin sheet while PLA is borderline ("eh it's alright"). The PCTG is the only one offhand I can recall being boogery. The others just get really stringy/hairy.
Are there any 'process profile' tweaks that you would recommend or just stick with the stock settings?
I cant seem to find the Engineering print surface on Bambu Labs Website anymore.
I'm having a pretty frustrating issue with oozing with this PCTG on all of my MK3s+ (stock and Revo6). its to the point where id say 50% of my prints fail either by crashing or just making a huge blob of filament on the hotend. Is there a profile available for the MK3S+?
I have tried a generic PCTG filament preset and modified a PETG preset with no luck. I have adjusted temps, cooling, speeds, and I'm about to start tweaking retraction to see if I can figure something out but would love some advice if you might have something other than what has already been posted.
I would love some print profiles for Prusa Slicer. I'm currently using Prusa XL with various nozzle sizes.
Another for Pruss Slicer and the MK3s+-MK4s printer lineup.
Where do the downloaded files need to be copied to show up in Bambu studio?
Having the same problem as Grant, above. Lot's of blobs in the middle of the model. Can't figure out the proper configuration.
Hey Jim,
I have found the best settings for me to minimize the oozing and blobs is to lower the temp to 250, turn my retraction up and my print speed all the way up to 250. What printer are you using? I also have my bed temp up at 80 and use bed weld to minimize warping. I notice better results when printing single items vs multiple items. I can upload my exact print settings for my prusa in a little bit.
I'm using a Bambu P1S. I literally just tried lowering the nozzle to 255 and the prints are a lot better at print speed of 200. Bed is still at 70 with a textured PEI so things stick pretty good. What's your max volumetric setting? Basically, this is pretty much my PETG settings. I guess that make sense considering the lineage.
So my changes worked for a single print, then I started getting A LOT of stringing when doing multiple models at once. I ended up using the settings overrides found here:

https://forum.bambulab.com/t/good-pctg-profile/28336
This helped with the stringing. I have 2 models printing right now and I don't see the same stringing going on so far.
I can see those helping. I also get more issues when printing multiple parts at once.
I might give your retraction settings a try. I am only at
Length - 0.8
Speed - 35
Min travel - 1
I wonder if wiping while retracting would help with printing multiple parts…..
What is your volumetric speed set at?
Mine is at 22.
I had mine set to 10. my new prints came out 99% perfect. No stringing at all between models and maybe only one small blob.
I bumped it up to 15 and started to get little hairs again.. so I think somewhere between 10-12 is good for me.
Hello, everyone; the Pro PCTG material profiles for the Bambu printers have been updated. I will share more details in a blog post in the next day or so about the changes and improvements. I'm confident this will provide a much better starting point for everyone to make geometry-specific changes.
I'll link it here once it's live.
I'm also working on PrusaSlicer profiles for the Mk4S and am working with others on profiles for the Mk4 and Mk3 variations.
Thank you!
Hey John.. What outer/inner wall speeds did you use with this profile?
Hello Jim,
Is what I'm currently doing on the 0.2mm Standard Bambu profile. I don't use any filament overrides.
Ok. I tried the new one and it was a big improvement. Unfortunately, there are still some issues that I can't seem to resolve, but we're getting closer. But I cannot figure out what is causing these layer blobs. Looks like it's too hot and it's oozing out. I noticed that there were bits on the plate as well, like they were sluffed off the nozzle at some point.
Ok, I fixed nearly all of the issues with the blobbing using retraction settings:
I'm still tweaking, but I've blown about 80 bucks on your filament trying to get them this good. Not an easy task. It's good plastic, but it's harder to print with than I suspected it would be.
First, I appreciate that you have created printer profiles for your PCTG filaments.
But after reviewing your PCTG TDS document, your PCTG web page and several of the PCTG .JSON and .INI profiles for Bambu Labs and Prusa. There are a number of anomalies that I have found when comparing your web page and published TDS specs for yout PCTG filament to the .JSON and .INI profiles you have published. Here are just a few examples.
Your website page for PCTG has the following Filament info:
Recommended Printing Temperature: 260-280C
Your published TDS for PCTG says the Nozzle printing temperature should be:
Nozzle Temperature, ˚C 250- 270
Yet, your print profiles do not use these ranges. For example the file "3D-Fuel PCTG Pro PCTG 2.0 @Bambu Lab X1 Carbon 0.4 nozzle.json" has the following:
"nozzle_temperature_range_high": [
"290"
],
"nozzle_temperature_range_low": [
"250"
],
The "3D-Fuel Pro PCTG - Prusa Mk4S.ini" file only states:
first_layer_temperature = 260
Your TDS for PCTG glass transition temp states:
Glass Transition Temperature, 76˚C
Yet this same .json file says:
"temperature_vitrification": [
"90"
],
And no value is defined in the MK4S .ini file.
The web page says the recommended print speed is:
Recommended Print Speed: 60 – 250 mm/s
Whereas the PCTG TDS recommended print speed is:
Print Speed, mm/s 40 – 80
The MK4S .ini files says:
filament_infill_max_speed = 200
filament_max_volumetric_speed = 24
And the .json file says:
"filament_max_volumetric_speed": [
"6"
],
and no setting for infill (or other) print speeds in mm/s.
Note: the Bambu Labs hardened steel hotend is hi-flow and capable of a max_volumetric_speed of 24 or more.
Please review and update your webpage and the .json, .ini printer profiles to be consistent with the TDS, or document why your profile settings may be different (e.g. from testing with high flow nozzles on Prusa and Bambu Lab printers, our recommended max printing speeds are higher than those listed in the TDS).
Thank you for providing profiles for MK4S on PrusaSlicer, but I've noticed (and some people on the Prusa forums have also noticed) that you only provide profiles for HF nozzles on the MK4S. Some of us use standard flow nozzles for various individual reasons. (Mine is because my every-day nozzle is a tungsten carbide nozzle so I don't have to change nozzles if I decide to print with an abrasive filament, and it doesn't come in HF.) Are you able/willing to add tweaked setting for standard flow nozzles for MK4S? What about the other Prusa machines, or make a generic machine agnostic profile?
Why is the max volumetric speed so slow? You have 10mm^3/s where regular PETG for the HF0.4mm is 24mm^/s. (Regular PETG is 12mm^3/s for the standard flow nozzles...) Are you just being exceptionally conservative with your max flow rate, or is PCTG significantly more viscous than PETG?
Have you considered providing profiles formatted for inclusion in the standard Prusa ini files at https://github.com/prusa3d/PrusaSlicer-settings-prusa-fff/tree/main so your PCTG profiles are with the other 3D-Fuel filaments at the top of the drop-down instead of at the bottom of the dropdown in the User profiles? Or is this a work in progress? ;-)
I can not get the profile to import for the Elegoo Centauri Carbon, elegoo slicer just says there are 0 configs imported.
John,

Thank you for continuing to update and improve the PCTG profiles for BambuStudio and OrcaSlicer. Please update the individual links for each printer/nozzle size to match the revised profiles you posted in the bundles on May 21st. There will likely be many people who do not read the whole post and end up downloading the older profiles.
Also there continues to be a disconnect between a number of your recommended profile settings (including nozzle temps) found on your webpage, your PCTG TDS doc, and your latest slicer profiles. Please clarify or correct as needed as they will cause confusion for many people trying to get the best from your filament. See attached picture for what I am referring to. Thanks, Andy
