Prusa Research CORE One+ vs Snapmaker U1
Technical comparison · Fused filament fabrication (FFF/FDM)
Choose Prusa CORE One+ if you need an integrated closed chamber and bed temperatures up to 120 °C to print technical materials in compact spaces. Choose Snapmaker U1 if you prefer native multi-color printing with four extruders without external accessories and pre-installed Klipper firmware at a lower price point.

| Software notes | Natively compatible with PrusaSlicer (based on Slic3r, open-source), but it works with any slicer able to generate Marlin-flavored G-code, such as Cura, ideaMaker or Simplify3D. The firmware is a Prusa-modified Marlin 2, fully open: no lock-in to proprietary software or protocols. The user has full control over the machine, but PrusaSlicer is recommended for optimal performance, as it includes exclusive profiles and features like dynamic flow calibration. | The primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows. |
The differences that matter
- Color management and print heads: Snapmaker U1 uses a native multi-extruder system for up to 4 colors without external accessories, whereas Prusa CORE One+ requires a separate module to reach 5 colors.
- Print environment and temperatures: Prusa CORE One+ features a closed chamber and a bed reaching 120 °C, optimal for advanced polymers; Snapmaker U1 is open and its bed stops at 100 °C, though its nozzle reaches 300 °C (vs Prusa's 290 °C).
- Electronics and Firmware: Snapmaker U1 natively integrates the Klipper ecosystem (Moonraker and Fluidd) controlled via Snapmaker Orca. Prusa relies on an open Marlin 2 firmware and is optimized for PrusaSlicer.
- Dimensions and build area: Despite a bulkier external footprint (58.4 × 49.9 × 73 cm), Snapmaker U1 offers a larger print area in X and Y (270 × 270 mm vs Prusa's 250 × 220 mm).
- Price and Power: Snapmaker U1 has a launch price of 849 € with a nominal power of 1150 W, while Prusa sits in a higher bracket (~1049–1349 €) but with lower stated consumption (240 W).
Which one to choose
Choose CORE One+ if…
Choose Prusa CORE One+ if your priority is printing temperature-sensitive materials, thanks to its native closed chamber and a heated bed reaching 120 °C. The more compact footprint (41.5 × 44.4 × 55.5 cm) is ideal for smaller workspaces, while supporting up to 5 colors via an optional add-on.
Choose U1 if…
Choose Snapmaker U1 if you need a larger X/Y build volume (270 × 270 mm) and want to print up to 4 colors simultaneously via a native multi-extruder system, with no external modules. It is the best option if you seek built-in Klipper firmware, 1080p camera connectivity, and a lower initial investment (849 €).
