Ultimaker 3 vs Prusa MK4
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Ultimaker 3 is a robust, dual-extrusion desktop 3D printer engineered to deliver high uptime and seamless workflow integration for professionals and educators. It features an intelligent print core system, active filament flow monitoring, and optimized print profiles that consistently produce accurate mechanical parts and intricate visual prototypes. Equipped with automatic bed leveling and NFC-enabled material recognition, the printer streamlines setup and minimizes user intervention. Its open filament system supports a wide array of advanced thermoplastics, while water-soluble PVA support material enables the creation of complex internal geometries with clean, easy post-processing.
The Prusa MK4 is the latest generation of Prusa Research's flagship FDM 3D printer line, known for exceptional print reliability, extensive documentation, and a strong open-source hardware philosophy that lets users repair and modify their machines freely. It features automatic bed leveling, input shaping for faster and quieter prints, and a load cell sensor that detects failed prints and pauses automatically, reducing wasted filament and unattended failures. Available as a pre-assembled unit or a build-it-yourself kit that doubles as an educational experience, the MK4 has become a benchmark reference printer that many other manufacturers are compared against.
Kit from $799, assembled from $1,099.
- Reliable dual extrusion system with easy-to-swap print cores
- Seamless integration with Cura slicing software and material profiles
- Automatic bed leveling reduces initial setup and calibration errors
- Water-soluble support enables complex internal geometries without manual cleanup
- Exceptional reliability and print quality

Prusa MK4 Reviews
3.5 (2)Highly recommend Prusa MK4
I picked up Prusa MK4 a while back and haven't looked back. Strong open-source community and documentation. One minor gripe: single extruder limits multi-material prints, but it hasn't been a dealbreaker. Would recommend.
Works, with some caveats
Mixed feelings about Prusa MK4 after using it for a while. On the plus side, strong open-source community and documentation. That said, higher price than budget 3d printers, which held us back from rating it higher.
