Help Tuning Overture Matte PLA on MK4S + MMU3 for High Detail, Low Cleanup
Hi all,
I’m looking for help fine-tuning Overture Matte PLA on a Prusa MK4S with MMU3 using a 0.4 mm nozzle. My goal is to get clean, highly detailed results with minimal post-processing, especially for multi-material prints (The dream, I know).
I’ve been working from the 0.10mm FAST DETAIL preset in PrusaSlicer and need the results to work across all 5 MMU slots with similarly behaving filaments.
I’ve already tried:
- The built-in Overture PLA profile in PrusaSlicer
- The Overture PLA profile downloaded from their site (originally for MK3—adapted to MK4S)
- A wide range of adjustments in the Filament tab including temperature (195–215°C), retraction length/speed, deretraction, wiping, and cooling behavior
Despite this, I’m still getting:
- Stringing, especially between vertical features
- Zits on the backside and around thin parts
- Surface fuzziness on detailed areas
Occasional “web walls” from consistent oozing between structures
If anyone has dialed in Overture matte PLA settings for the MK4S/MMU3, or has general tips for high-detail multi-material prints with reduced cleanup, I’d love to hear your suggestions.
Thanks in advance!

I don't own a MK4S or a MMU so I can't help you with specific settings. One thing I know, though. Overture Matte PLA sticks with unusual force to the smooth plate. Better use a satin or textured plate to avoid problems removig the model. .If you want or need to use a smooth plate, lower the bed temperature to a maximun of 50C and use a layer of adhesive between plate and print.
