🌟 Prusa CORE One+ Kit – Enclosed Chamber FDM 3D Printer for Assembly
The Prusa CORE One+ Kit is the assembly version of the award-winning CORE One+: the same robust and reliable machine, with the advantage of building it yourself over a weekend, getting to know every component inside out. With an enclosed chamber, CoreXY, active temperature control up to 55°C, Nextruder extruder with 360° cooling, steel exoskeleton, and ready to print PLA with the door closed thanks to the automatic ventilation system, it is the ideal choice for makers, enthusiasts, and professionals who want a high-performance machine with a complete understanding of the hardware.
🔹 What sets the Prusa CORE One+ Kit apart?
- Enclosed chamber with active temperature control up to 55°C — automatic ventilation for PLA/PETG with the door closed; enclosed chamber for ABS, ASA, PC, and PA without warping.
- Automatic ventilation system — opens for low-temperature materials and closes for technical materials, without manual intervention.
- Nextruder extruder with 360° cooling — overhangs up to 75° without additional supports; proven dimensional accuracy.
- All-steel exoskeleton — maximum rigidity, simple maintenance with a screwdriver, no glued parts.
- New bayonet spool holder — compatible with various spool sizes; ready for direct-feed drybox.
- Integrated Input Shaper + Phase Stepping — eliminates resonance and vibrations for accurate high-speed prints.
- Loadcell Sensor — automatic first layer leveling without manual adjustments.
- Two filament sensors — in the side path (with FLEX mode via physical switch) and in the print head.
- 3.5" 65k color touchscreen + integrated RGB status bar in the chamber and on the display.
- Full offline mode — no account or internet connection required; removable Wi-Fi module for high-security environments.
- MMU3 compatible — already available for CORE One, up to 5 filaments simultaneously.
- Prepared for INDX upgrade (coming soon) — tool changing system for up to 8 materials with magnetic induction heating and near-zero waste.
- HT Hotend Upgrade available — prints up to 400°C for industrial materials like PEKK-CF, PPS-CF, PPSU, and PPA.
- Open-source firmware and software — PrusaSlicer, Prusa Connect, and Prusa App included.
