=== Pre-order. Expected April/ May 2025. See table below for details. ===

The STōN-Wolf is built to last. No corners cut. With a 300mm build plate, a flying gantry, and a 12mm thick CNC-machined metal frame. Powered by a 48V motion system, Klipper firmware, and an RPi CM5, it’s designed to redefine speed and quality. This is a machine that stands at the cutting edge of 3D printing. Proudly designed and built in the Czech Republic.

Why buy STōN ?

Get more with less

The design is a consequence of stripping down the parts to the absolute essentials. Occams razor. The main structure is made with CNC precision. Super flat and milled plate from German and Czech suppliers. Its not about price, we wanted the best.

Latest electronics

As part of the no corners cut philosophy, the electronics have been picked to bring the best experience. Original Raspberry Pi CM5 made in UK. As well as being open for tinkerers that demand more out of their hardware. If they ever make a RPi CM6, you can also swap it out. A bit of "future-proofing" for peace of mind.

Effective Cooling & low tool weight

The high output blower system brings colder air from the back. Bringing the high pressure to the nozzle from a contained box to reduce noise.

  • Built with Pride, 1 by 1

    Each machine is assembled from start to finish by 1 master builder in Prague, Czech Republic. This ensures the highest quality of machine. The Builder-Number is marked in the frame. This enables you to get support directly from your builder.

  • Quick, and precise

    Travel speeds at 1500mm/sec put it at the top of the industry. And the smooth print speeds of 400mm/sec don't result in sloppy details. If you feel daring you can turn it up without breaking things.

  • Automatic load cell calibration

    Hassle free first layers, no matter the nozzle. The loadcell detects contact directly to save you from wasting time calibrating.

  • Stock Klipper and Mainsail

    Refreshing, Nothing skinned or re-branded. The experience you already know and love. It's all yours. Kudos to all those who made it open-source.

  • Open source design

    Coming soon after the first units, files to customize and maintain the printer will be made available. If we use open-source, it makes sense to also be open source.

  • Enclosure coming

    The printer was the priority for us, but it was obvious the most common filament printed is PLA and PETG. So an open printer was the priority. However, we know some people want an add-on enclosure. So it is coming. Expected summer 2025.

Build Style and Volume
• Unique Cartesian “Flying Gantry” style.

  • Shorter belts vs CoreXY.
  • Frame remains rigid even in the center of the bed where we print the most.
    • 300x300x285mm build volume. (if you use a shorter hotend you can get full 300 cube build volume. )
    • 12mm thick CNC frame plates from Czech and German producers. Milled flat.
    • Carbon fiber Y-gantry with high-temperature epoxy, 18mm thick.

    Motion and Performance
    • 48v XY motors with a driver max of 56v at 4.6amp (“Why not, life is short”).
  • LDO stepper motors for their reliability and high speed.
    • 1500mm/sec travel speed at 30k accel (motors warm, not boiling).
    • 300-600mm/sec print speed at 12-60k accel, depending on nozzle, filament type, and layer height (300-600mm/sec at 30k is a realistic perimeter speed).
    • 16mm Z-axis rods with precision bearings.
    • Quality “MGN9H size” XY Linear rails. Identical lengths for part simplicity.

    Bed and Build Plate
    • VORON/LDO 305mm 600watt bed, 10mm thick cast and milled. Special thanks to VORON and LDO. Especially you Jason, thank you.
  • Bed probing using Genuine Adafruit load sensor
    • LDO Darkrock305 professional build plate.

    Hotend and Cooling
  • Micro-Swiss CM2 Reprap nozzle (v6 size)

    • High-temp heatsink fan for long life in the upcoming enclosure.
    • CPAP 7040 remote fan with silencer box (not silent, but helps reduce noise).

    Electronics and Software
