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 using our materials, please let us know, and we can revise and improve our stock profiles based on your feedback.

Do you have a 3D printer that 3D-Fuel hasn't developed a profile for yet? Here are the easy steps to develop one for yourself.

How to import a 3D-Fuel filament and/or process profile into Bambu Studio

For the Bambu Lab Printers, we've developed both the Filament Profile and the Process Profile to help you get the best quality from Pro PCTG.

If you use the stock process profiles in Bambu Studio, please switch your sparse infill pattern from "grid" to either "gyroid" or "cubic". Grid infill crosses itself within the same layer, which can cause PCTG to build up on your printer nozzle.

The Process Profiles include changes to print speeds, acceleration, infill pattern, and a few other items to provide exceptional surface finish and strength that go beyond what the Filament Profile can achieve. The Process Profile for each printer model is in its corresponding section. You can jump to the specific printer model by clicking the link in the model names below.

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.

Update 5/5/26

Bambu Studio has introduced a new filament profile variable, "Metal Stickiness" which influences the behavior of the "Reduce infill retraction" setting in the Process profile (under Others -> G-code output.

Since Pro PCTG is a very sticky material, having the printer retract, even in the infill sections, can help reduce oozing and buildup of PCTG on the nozzle.

We've updated all of our Pro PCTG profiles to have Metal Stickiness set to "High" so that it should influence the "Reduce infill retraction" setting (set to Auto by default) to effectively disable "Reduce infill retraction".

Update 3/24/26

We've updated the cooling strategy implemented in the 2/26/26 update to the Bambu Lab X1C across all Bambu Lab Pro PCTG profiles. This should result in stronger layer-to-layer bonding results and stronger parts.

Update 2/26/26

With the release of Bambu Studio 2.5.0, Bambu introduced an optimized prime-tower strategy for PLA & PETG mixing in a single print. PCTG has the same adhesive characteristics as PETG (since they're both co-polyesters), and Bambu Studio uses an "adhesiveness category" to determine whether materials will bond to each other.

Our update today has updated the adhesiveness category for all of our Pro PCTG profiles.

This update also includes a cooling strategy for the X1C that should improve layer-to-layer strength. We'll work on implementing this improved layer-to-layer bonding cooling strategy across.

Effectively, it reduces the cooling fan speed and turns off the chamber exhaust, allowing the previous layer of the print to retain more thermal energy. This means that the next layer laid down will bond more completely with the previous layer.

Update 1/6/26

We have updated the naming structure of our Pro PCTG profiles for Bambu Studio to be much more compatible with the Bambu Lab AMS devices. Previously, the material profile name was "Pro PCTG", but since the AMS relies on the material TYPE being the first part of the name, the 3D-Fuel material profile name is now "PCTG Pro".

This will make it much simpler to select the filament you are loading in the AMS on the Bambu printer touchscreen. Please note that you may need to tap the "update" icon in the upper right of the screen, directly to the right of the material name, to update your available custom materials.

How to Use 3D-Fuel Profiles In Bambu Studio

To import the 3D-Fuel Pro PCTG profile into Bambu Studio, please 

  1. Open Bambu Studio
  2. Click File
  3. Hover over Import
  4. Click on Import Configs
  5. Navigate to the location of the filament profile file (or files) that you downloaded
  6. Select the file(s)
  7. Click Open
    1. After, if you see a dialog box that says something along the lines of, "A config exists with the same name: ....................; do you want to replace it?"
      1. Click Yes or Yes to All (note: this WILL overwrite any filament profiles that you already have with the same name)
  8. If successful, you will see a dialog box that says, "There is X config imported. (Only non-system and compatible configs"
    1. The 'X' should match the quantity of config files that you selected in step 6
  9. Click OK
  10. The imported profile should now be visible in your filament drop-down under the User Presets Section under "Custom"

X2D

We'll be building out more profiles for the X2D, including profiles to use Standard PLA+ as a support interface material, but this is a really solid first profile, especially paired with the 0.2mm High Quality process profile.

X2D - Pro PCTG with Standard PLA+ Breakaway Support Interface

The dual nozzles of the X2D work beautifully for utilizing Standard PLA+ as the breakaway support interface for the Pro PCTG. To do this, you must ensure that the chamber heat is turned off, or the Standard PLA+ will jam in the hotend/extruder

3D-Fuel Standard PLA+ is the only PLA filament that has been successfully tested so far. It works well since it prints at 240 °C, which ensures a strong enough bond between the Pro PCTG and PLA support interface layers.

The support structure should be printed in Pro PCTG. This results in fewer material changes, lower print time, and more stable support structures.

For best results, pair the Pro PCTG profile below (chamber heat is off, and the bridging fan is disabled) with the Standard PLA+ profile and the Process profile below. For convenience, all 4 profiles are available in a zip folder.

      • 3DF PCTG Pro + Std PLA+ Breakaway Support 0.20mm Standard @BBL H2DP (this is the print process profile - it inherits the base 0.20mm Standard @BBL H2D profile) 

The dual-nozzle print head of the Bambu H2D makes it ideal for printing separate breakaway support material (Std PLA+) with Pro PCTG. 

It is not recommended to run both materials through the same nozzle because of their substantially different melt flow indices. When you extrude PCTG right after PLA, the PLA coats the surface of the Pro PCTG rather than being quickly purged out by the Pro PCTG. This results in weak layer-to-layer bonding.

We have some customers who choose to pass both materials through the same nozzle on printers that do not have 2+ nozzles. They have to purge as much volumetric capacity as possible to clear all the PLA out of the Pro PCTG. This results in a lot of Pro PCTG material waste.

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 5-5-26.

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.

As of 2/26/26, PrusaSlicer includes 3D-Fuel filament profiles, making it easier than ever to use 3D-Fuel filaments with Prusa 3D printers.

K2 Plus

We have found that, even with seemingly identical profile settings, Creality Print gets better print results with Pro PCTG than Orca Slicer does. If anyone finds a solution, please let us know! It seems to be related to the |handlig of retraction on fine details. Creality Print has noticeably fewer fine strings on small print features.

    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.

  • John Schneider

    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.

    0
  • John Schneider

    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.

    0
  • ConnorB

    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.

    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.

  • Grant Spitz

    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.

  • Jim

    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.

  • Jim

    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.

    0
  • Grant Spitz

    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?

    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.

    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!

    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.

  • Jim

    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? ;-)

    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

    Oops. The updated MK4S (and the new CORE One) PrusaSlicer profiles no longer import and create a new preset with the name you specified. They are importing as a modification to the base preset that you had modified.

    For example, if I import "3D-Fuel Pro PCTG @MK4S HF 0.4mm.ini" (It doesn't import as a config bundle like the previous .ini file did, just as a config), it shows in my filament preset list as "Generic PETG @MK4S HF0.4 (modified)" with most of the settings pane titles colored to indicate changes (orange with the dark-mode coloring that I use).

    I recently received an Elegoo Centauri Carbon and downloaded the json here for Pro PCTG, however, it will not import into Elegoo Slicer.

    I'm on Windows and use File > Import > Import configs but it gives me the error of:

    "There are 0 configs imported. (Only non-system and compatible configs) Hint: Make sure you have added the corresponding printer before importing the configs."

    I definitely have the printer added, as it's the only reason I'm using Elegoo Slicer.

    Also, I get the same error with OrcaSlicer.

    I've imported the Bambu Pro PCTG profile into Bambu Studio without any issues.

    I've also tried copying the json file directly into the %appdata% Elegoo Slicer user folder for filament presets and it doesn't work from there either.
