Bambu Lab H2C vs Prusa Research MK4S
Technical comparison · Fused filament fabrication (FFF/FDM)
The two machines do the same job, but the H2C costs more than double: €2249 against €999. The difference buys volume, an enclosed chamber and multiple extruders; the MK4S stays open, with Marlin firmware and no account.

| Software notes | The printer is operated through Bambu Studio, Bambu Lab's open-source slicer based on PrusaSlicer, available for Windows, macOS, and Linux. Remote control is available via the Bambu Handy app or Bambu Suite. The machine includes a 5" color touchscreen for local operation and connects over dual-band Wi-Fi. The firmware is proprietary; Klipper is not natively supported. | PrusaSlicer (optimized) and Prusa Connect for remote control. The machine accepts G-code from any slicer (Cura, Simplify3D) and communicates via USB, Ethernet or Wi-Fi using an open Marlin-based protocol. Compatible with OctoPrint and offline management. Does not require a Prusa account to print, unlike machines with proprietary firmware that block features without connection. |
The differences that matter
- 330×320 mm bed against 250×210 mm → a part 300 mm wide fits only on the H2C.
- Enclosed chamber and multiple extruders against an open frame with one extruder → only the H2C prints in a closed chamber and with several materials in one job.
- Bambu Studio and proprietary firmware against open Marlin and optional Prusa Connect → the MK4S prints without an account and with G-code from any slicer.
Which one to choose
Choose H2C if…
you print large parts or parts in several materials, in an enclosed chamber: a 330×320 mm bed, 325 mm of height, multiple extruders and a nozzle up to 350 °C as declared. The trade-off is the price, about €1250 more, and the proprietary firmware: Klipper is not natively supported.
Choose MK4S if…
you want an open, cheaper machine, about €1250 less, with PrusaSlicer, G-code from any slicer and no account needed to print. You accept a 250×210 mm bed, no enclosed chamber and a single extruder.
