Based on the Klipper mainboard, it offers a large working area of 225 × 225 × 265 mm and printing temperatures up to 300°C, while allowing you to use a wide range of filaments – from PLA (Polylactic Acid) and PETG (Polyethylene Terephthalate Glycol) to ABS (Acrylonitrile Butadiene Styrene), TPU (Thermoplastic Polyurethane), or nylon. With a powerful extruder and 121-point automatic leveling, the Neptune 4 Pro can handle both rapid prototyping and large, demanding technical prints.

Fast Printing Without Compromise
The printer reaches a maximum speed of 500 mm/s, with a recommended speed of 250 mm/s, ensuring excellent quality with short waiting times. Supported by the Klipper motherboard, a powerful ARM (Advanced RISC Machine) 64-bit 1.5G quad-core processor, and features such as Input Shaping and Pressure Advance – it provides an exceptionally smooth model surface and uniform filament sealing. It is an excellent choice for those who expect not only precision but also real time savings.
Efficient cooling system, well-designed build plate
Two 4015 dual-sided fans and four 4020 fans ensure efficient heat dissipation and cooling of the printed models. Additionally, the device's heated bed is divided into two sections with different power outputs – 150 W and 100 W. This solution guarantees lower energy consumption and protects against overheating, resulting in more stable and safer operation.
Improved hotend and efficient extruder
The Neptune 4 Pro is equipped with a high-performance direct drive extruder with dual gears, which ensures precise and stable filament feeding, regardless of the type. Additionally, the improved hotend design uses a copper-titanium heat break and a nozzle capable of operating at 300°C. This solution allows printing with a wide range of materials, including those that require higher temperatures and better flow.
Guidance Stability and Structural Rigidity
The printer is equipped with metal guides for the X and Y axes, which, combined with double U-shaped bearings, ensure smooth, precise, and stable guidance of the print head. Additionally, a reinforced, expanded Y-axis profile increases the rigidity of the entire structure, resulting in higher print quality, especially at high speeds.
Automatic leveling and flexible platform
The printer uses automatic bed leveling at up to 121 points (11×11 grid), which ensures perfect adhesion and a perfectly aligned first layer. Additionally, the user can use the buttons below the work platform to manually adjust the level – for even greater accuracy and complete control of the printing process.
Intuitive operation and flexible communication
A detachable 4.3″ touchscreen allows you to easily preview your model and pause the print. In addition, the printer allows file transfer via USB (Universal Serial Bus, a universal connection for data and power) or LAN (Local Area Network, a local computer network).
Additional Features
With a filament sensor and a resume function after a power outage, you can be sure that printing will not fail, even if something unexpected happens. The LED lighting (light-emitting diode) on the nozzle makes it easier to observe details up close, while an additional LED strip provides uniform illumination across the entire work area.
More space for your ideas
The Neptune 4 PRO offers a workspace of 225 × 225 × 265 mm, allowing you to create both small prototypes and more intricate models. This volume gives you great design freedom without the need to split models into parts.
