Tumaker NX 300 Modular – FDM/Pellet 3D Printer

Tumaker, manufacturer of industrial 3D printers such as the Big Foot 500 Modular industrial 3D printer, has also developed the NX 300 Modular desktop 3D printer, allowing users to choose between single extrusion with filament or pellets, or dual extrusion with filament, pellets, or both. The NX 300 Modular features a closed enclosure (with fan and HEPA filter) and combines the reliability, versatility, robustness, ease of use, and aesthetic design typical of Tumaker products.

The total build volume also depends on the chosen extrusion system. To consult the specific build volumes of each NX 300 Modular printer configuration, refer to the datasheets available in the Downloads section and the Specifications section.

The NX 300 Modular 3D printer has been designed to offer maximum performance under the most demanding conditions. With minimal maintenance, the NX 300 Modular provides maximum cost-effectiveness, and its components, manufactured and assembled in Europe, guarantee reliability and robustness.

Tumaker Extrusion Systems

Tumaker addresses different manufacturing needs by offering 5 different extrusion systems for the NX 300 Modular 3D printer:

1. Single HR Direct Drive extrusion for filament.
2. Single extrusion for pellets.
3. HR Dual Direct Drive extrusion for filament.
4. Dual extrusion for pellets.
5. HR Dual Direct Drive extrusion for filament and pellets.

The NX 300 Modular 3D printer is capable of working with almost all materials developed for 3D printing, whether in filament or pellet format. The materials compatible with each NX 300 Modular extrusion system, as well as the maximum extrusion and bed temperatures, are listed in the table below:

Thanks to the high maximum extrusion temperatures and the ability to 3D print with pellets, the NX 300 Modular 3D printer allows the use of a very wide range of materials, from standard basic plastics and flexible materials to fiber- or particle-reinforced engineering materials, ceramic and metal polymers, and advanced high-temperature polymers from the PAEK family.

Single HR Direct Drive extrusion for filament

The HR Direct Drive extrusion system for filaments features a professional print head with a state-of-the-art dual mechanical gear system with 10 kg pushing force. This amount of force ensures proper filament flow to the nozzle and helps avoid clogs or underextrusion. This extrusion system, in single or dual version, is ideal for users working exclusively or mainly with flexible filaments.

The NX 300 Modular filament extrusion system can operate at a maximum temperature of 300 ºC, allowing the use of high-temperature filaments such as ASA, ABS, PETG, HIPS, PC, and flexibles. Many nozzle diameters can be used with the NX 300 Modular filament extrusion systems, ranging from 0.15 mm to 0.8 mm. The nozzle can heat up to the maximum 300 ºC in about 2 minutes and the exclusive ANS ultra-fast nozzle change system enables direct nozzle replacement.

HR Dual Direct Drive extrusion for filament

The Tumaker Dual Direct Drive HR extrusion system opens a world of possibilities for using different colors and materials in the same print or 3D printing complex structures with support materials, without the risk of temperature contamination. Dual extrusion NX 300 Modular 3D printers also use quick-change, swappable extruders in an IDEX extrusion system, meaning there are two extruders that move independently along the X-axis and can be swapped with minimal effort.

The extruders used in the NX 300 Modular extrusion system are fully machined, ensuring reliability and durability. The IDEX extrusion system also allows printing in duplication or mirror mode, significantly boosting productivity.

Additionally, the built-in filament runout sensor enhances 3D printing safety, allowing users to resume a paused print from the exact point once a new filament is loaded. Another productivity-enhancing feature of the NX 300 Modular printer is its ability to handle large-format spools, preventing up to 8 filament changes and reducing user intervention and failed prints due to filament shortages.

Single and dual pellet extrusion

When it comes to single and dual pellet extrusion with the NX 300 Modular printer, it’s a step forward in making additive manufacturing more accessible and efficient.

3D printing with pellets opens up the use of materials not available in filament form, self-developed materials, or certified pellets for the food, rail, automotive, medical, and many other industries.

The NX 300 Modular dual pellet extrusion system (capable of reaching up to 300 ºC) includes a head designed by Tumaker with integrated dual temperature sensors. Recommended material: circular pellets with a diameter of 3–5 mm.

Dual extrusion for filament + pellets

Tumaker has gone further by introducing a fifth printing mode: dual mode, where one head extrudes filament and the other extrudes pellets.

This level of modularity and versatility makes the NX 300 Modular an extremely valuable and powerful additive manufacturing tool, allowing users to adapt the NX 300 Modular printers to current production needs and experiment with the complexity of 3D printed parts and the types and formats of materials used.

Ease of use and safety

The NX 300 Modular 3D printer features a 32-bit processor ensuring print stability and enabling high printing speeds. The innovative TMC2660 drivers make the NX 300 Modular ultra-silent, with a noise level of 44 dB (40 dB with the enclosure door closed). High-precision ball screws enable faster printhead movement, and the 45 mm aluminum frame ensures maximum stability.

The NX 300 Modular offers multiple connectivity options: USB, WiFi, MicroSD card, or Ethernet. The user interface is a 7" color touchscreen and it can be controlled from a PC, tablet, or even smartphone. The software that comes with the NX 300 Modular is Simplify3D, and it includes a perpetual license for user convenience.

Advanced desktop 3D printing

The Tumaker NX 300 Modular is a powerful desktop solution for advanced, versatile, and efficient additive manufacturing. With its fast-heating, semi-automatic leveling build plate, quick-change nozzle, a variety of nozzle diameters, safety features, and user-friendly interface, the NX 300 Modular enables printing with a wide range of filament and pellet materials, including the use of supports or multiple colors and materials in a single print session. The Tumaker NX 300 Modular 3D printer will deliver high-quality, complex parts for any project, whether for prototyping, final production, or experimentation.
