Anycubic Kobra S1 Max Combo vs Qidi Tech i-Fast
Technical comparison · Fused filament fabrication (FFF/FDM)
Two enclosed machines with a large bed but from different generations: the Kobra S1 Max Combo is from 2025 and costs about €950, the i-Fast is from 2021 and sits around €2,150. Whoever still picks the i-Fast does it for the two extruders.

| Software notes | The firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for core printing functions. | The machine comes with the proprietary Qidi Print software, a slicer based on proven open-source architectures, specifically optimized for the profiles of the technical materials supported by the printer. Users can still generate G-code using other widely adopted third-party slicers on the market, such as Ultimaker Cura, PrusaSlicer, or Simplify3D, after manual configuration of machine and extruder parameters. Although it lacks native cloud features or advanced remote connectivity for corporate fleet management, it supports direct file transfer via local Wi-Fi or USB drives, ensuring a secure offline workflow for intellectual property protection. |
The differences that matter
- €949 vs €2,150 → about €1,200 left over for filament and spares.
- Declared top speed 600 mm/s with input shaper vs 150 mm/s without → a part that takes hours prints in far less time on the Kobra.
- One extruder vs two → two materials in the same part is only possible on the i-Fast.
- Bed 350×350 mm vs 330×250 mm → on the i-Fast the short side caps parts at 250 mm.
Which one to choose
Choose Kobra S1 Max Combo if…
You need a 350×350 mm bed with 350 mm of height and shorter print times: declared top speed is 600 mm/s, with input shaper, the nozzle reaches 350 °C and the bed 120 °C, and colors go up to 4. You spend about €1,200 less. The trade-off: there is a single extruder.
Choose i-Fast if…
You need two real extruders, for instance to print one part in two materials, and the machine has them as standard: up to 2 colors. You pay €2,150 against €949, with a declared top speed of 150 mm/s, no input shaper and a 330×250 mm bed.
