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 - 0.4mm Nozzle
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.
The Bambu profiles were updated on 11-8-24. Learn more about the changes from the previous profiles.
Prusa 3D Printers - 0.4mm Nozzle
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.
