| Software notes | Equipped with Kobra OS, a Klipper-based firmware, controllable via a 4.3-inch touchscreen. Compatible with Anycubic Slicer and third-party software like OrcaSlicer. Features Wi-Fi for remote control via app. Multicolor printing requires the ACE Pro module, sold separately. | 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 3 Max 3D Printer if…
you value work area, max print speed and maximum z height. «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.»
Choose Neptune 3 Pro if…
you value price and max bed temperature. «A heated bed reduces the thermal gradient between the part and the environment, limiting warping and delamination. Up to 60 °C covers PLA and flexible materials. Between 80 and 110 °C it enables PETG, ABS, and ASA. Above 110 °C it is necessary for PC and high-temperature technical materials. Bed temperature should be evaluated alongside nozzle temperature: a high-rated bed adds little value if the nozzle cannot reach the corresponding threshold.»
