Kobra S1 Max vs Neptune 3 Pro
Technical comparison · Fused filament fabrication (FFF/FDM)
Kobra S1 Max and Neptune 3 Pro are not direct competitors: very different prices (~3.1×). Neptune 3 Pro costs less (~€229) and is the entry-level choice; Kobra S1 Max offers more capability at a higher price (~€699). Judge them by budget, not head-to-head.

| 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 ordinary printing operations. Unlike the Combo version, the ACE 2 Pro module is not included in the box. | The operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks. |

Which one to choose
Choose Kobra S1 Max if…
you value max print speed, work area and maximum colors. «The rated maximum speed indicates the theoretical hardware limit, not the everyday working speed. Faster machines reduce print times on simple geometries, but real-world speed depends on material, geometry, required surface finish, and slicer settings. Values above 200–300 mm/s are meaningful only on machines with CoreXY kinematics, active input shaping, and a stiffened mechanical frame.»
