Prusa MK4S HF
The Prusa MK4S High-Flow variant is the MK4S configured with the CHT-geometry high-flow nozzle as primary tooling, optimized for maximum throughput on the same 250 × 210 × 220 mm i3-style Cartesian platform. The high-flow nozzle uses a multi-channel internal geometry to increase melt-zone surface area, achieving 24 mm³/s volumetric flow versus 16 mm³/s on the original MK4 and enabling significantly faster wall and infill speeds. Combined with the MK4S’s 360-degree turbine cooling and input shaper, it is well suited to production environments or users regularly printing large volumes of PLA, PETG, or ASA.
Pros
- 24 mm³/s volumetric flow rate enables faster print speeds without compromising quality
- CHT nozzle geometry improves thermal transfer for consistent extrusion
- Full MK4S feature set: 360-degree cooling, load-cell leveling, input shaper, NFC
- Nozzle is user-swappable; standard nozzles remain compatible
Cons
- High-flow benefit is most pronounced with speed-capable filaments
- Same physical build volume as the MK4/MK4S; no additional print area
- Still a bed-slinger; print-speed ceiling is lower than CoreXY platforms at equal quality

Frequently asked questions
Does Printago work with the Prusa MK4S HF?
Yes. Printago manages the Prusa MK4S HF over your local network through PrusaLink, with cloud slicing, automatic job routing, and remote monitoring.
How do I connect the Prusa MK4S HF to Printago?
Enable PrusaLink on the printer. Find the PrusaLink password under Settings → Network → PrusaLink. Install the Fuse bridge, then add the printer with its host/IP and PrusaLink credentials.
Can I manage multiple MK4S HF printers with Printago?
Yes. Printago is built for production fleets: route jobs across many MK4S HF units, mix them with other brands, and run the whole farm from one dashboard.
Do I need a Raspberry Pi or extra hardware?
No. Printago connects over your local network through the Fuse bridge, which runs on your computer or in Docker, with no Raspberry Pi, no soldering, and no extra hardware.
