Calibrate Real Filament PETG Settings

Hi fellow Prusa users 🙂

I recently made the upgrade to the MKS version of the printer. As my NGEN did run out i ordered some PETG from "Real Filament" company.

Its quite cheap and easy to get by in Europe: https://reprapworld.com/products/filament/real_filament/petg/real_petg_smoky_black_spool_of_1kg_1_75mm/

Unfortunately the Prusa Settings for PET did not do the trick for me and i had to search the net quite a bit to find settings that produce good prints.

Here i want to share my settings as i think they are quite good for PETG but also want to get some hints to dial it in a bit better and make it perfect 😀

You can Download my Settings for the Prusa Scli3r here: https://drive.google.com/open?id=0B6IyuWA33ROBTE9zT1Z2VGNRS2c

Here is my best print so far with the settings from above.


What could i try for a better top finish?


There is some filemant in one of the holes. Ideas why just one? Thanks


What could cause these "lines" ?


Uneven lines.

If you have any suggestions how to make it look even better i would greatly appreciate them! 😀

PS: Yes that is PEI on the botton. This PETG sticks like hell. Make sure to cool the bed before removing.

Thanks for your help and have fun with the settings 🙂

Re: Calibrate Real Filament PETG Settings

If you clean the PEI with Windex window cleaner, it leaves behind a residue that will prevent the PETG from sticking so well, but still stick plenty.

You should NOT do PET on PEI clean due to this adhesion. I like windex, but some use glue stick.

Since I don't have, nor do I want, a google account, I can't see your settings. It would be better if you added them as an attachment (ZIPed if needed).

I think you should slow the printing down some to improve your print quality.

Hi Aaron,

I changed the settings in the Google account you should not need an account now to access the files.

Here is my speed tab:


Any particular recommendations ?

Re: Calibrate Real Filament PETG Settings

I think you have under extrusion. Possibly because you seem to print at 235 degrees, which is too cold. Try 245 for better results.

Re: Calibrate Real Filament PETG Settings

I would think there is a European equivalent. It is just a window cleaner.

Im using a brand named Ajax (Sweden). This is manufactured by Colgate so i bet it will be available almost everywhere but maybe under different name.
I think any of the blueish window cleaner will work.

Re: Calibrate Real Filament PETG Settings

if you are from the netherlands, you could try glassex instead of windex. Or the knock-off from action, which works just as well.
I am using the orange petg from real and have found that it prints best at 245 nozzle and 70 degrees bed. all other settings i have left as is from the prusa pet tab and just saved the adjustments to a new filament profile.
My prints are just as good as with pla so i'm happy with these settings.
Before every print i clean the bed with glassex and prints come off without any drama.

Adjust your z-height so it just sticks well enough to the bed that you have to push it with a fingernail to make it come loose but not so much that you have to scratch it and you'll be fine.

good luck printing real petg ☺

Hi Patrick,

Thanks for the replay. I found out that the blue ajax cleaer also works good 🙂

As for the settings, i have to really print slow 10ms so the outer layers look really good. Did you achieve better results with higher speeds ? (I uploaded a picture to my google files, they are updated now too :-))

I printed a temp tower and i seem to geht the best results with 335 degrees of the nozzle 245 is melting some fine structures. But even with 335 degrees i get fine hairs, stringing but it got better.

Any other ideas ?
