Below are the filaments that repeatedly deliver top results on MK4, MK3.5, MINI+, and XL.
Best PLA for Prusa
Prusament PLA (The Gold Standard)
- Manufactured in-house by Prusa Polymers – We were not satisfied with the quality of filaments on the market. So we decided to make our own. As a part of Prusa Research companies group, we are the only 3D printer manufacturer with its own filament production.
- Premium-grade materials and thorough testing – The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
- High Quality you can check yourself – We are the only manufacturer that gives customers the option to fully inspect parameters of every filament spool. Just scan a QR code on the spool to see all details online.
- 0. 02 mm Manufacturing Precision – We believe the industry standard of 0. 05 mm isn’t sufficient for perfect 3D printing. Instead, we 0. 02mm precision and highly-consistent colors in our filaments.
If you want the cleanest layers, the most consistent diameter, and the least wasted time, Prusament is unmatched.
- 100% traceability (every spool has QC data)
- Excellent color accuracy
- Incredibly reliable first layers
- Perfect compatibility with default profiles
Downside: the price. But professional users still choose it because it simply performs every time.
Polymaker PolyLite PLA (Best Third-Party Alternative)
Many MK4 and MINI+ owners use PolyLite PLA as their “daily driver” because the quality is close to Prusament at a lower cost.
- Clean winding
