Prusa Research CORE One+ kit vs Snapmaker U1
Technical comparison · Fused filament fabrication (FFF/FDM)
Same job, two ways of handling colour: the U1 has four toolheads and needs no accessory, the CORE One+ kit prints in an enclosed chamber and needs an add-on module for multicolour. The U1 costs about €200 less.

| Software notes | Prusa firmware based on Marlin, fully open source, with built-in input shaper for faster and cleaner prints. Official slicer: PrusaSlicer (free, optimized profiles), compatible with Cura and Simplify3D. Control via USB, Ethernet or Wi-Fi with Prusa Connect (optional). No filament DRM: full freedom to use third-party materials. | 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
- Four toolheads against one extruder plus an add-on module → multicolour is built into the U1, on the CORE One+ kit you add a module.
- Enclosed chamber against an open frame → only the CORE One+ kit prints inside a closed chamber.
- 270×270 mm bed against 250×220 mm → a part 260 mm wide fits only on the U1.
- Marlin with PrusaSlicer against Klipper with Snapmaker Orca and a 1080p camera → the software you use to prepare and follow the print changes.
Which one to choose
Choose CORE One+ kit if…
you print in an enclosed chamber, with open Marlin firmware, no account and no filament DRM, and only need multicolour now and then. The trade-off: multicolour, up to 5 colours, needs an add-on module, the bed is 250×220 mm and you pay about €200 more.
Choose U1 if…
you print in several colours regularly: four toolheads, no accessory, on a 270×270 mm bed. You accept a machine without an enclosed chamber, with 4 colours at most.
