Product description: Micro Swiss FlowTech™ hotend for Elegoo Neptune 4 Plus / 4 Max printers
Hotend FlowTech™ from Micro Swiss for the Elegoo Neptune 4 Plus and 4 Max printers is a modern and efficient solution that significantly improves the quality and comfort of 3D printing. Thanks to its innovative hotend system , it eliminates common leakage problems, and nozzle replacement is simple, quick, and safe . The kit includes all necessary components, including a heater, thermistor, and heatsink, which are fully compatible with the mentioned printer models. After installation, there's no need to modify any software or firmware settings —everything works immediately after plugging in. It's an ideal solution for both professionals and 3D printing enthusiasts seeking reliability and high performance in everyday 3D printing work.
Main features of the hotend
- No filament leaks: Nozzle and thermal break are combined into one hermetically sealed unit, eliminating filament leaks and preventing material waste
- Easy nozzle change: nozzle change is quick, safe and requires no tools or heating - it can be done with one hand
- High throughput: Ceramic heater barrel and wide melt zone provide excellent material flow rate for faster, more efficient printing
- Durable construction: the all-metal construction of the hotend guarantees its durability, allowing printing with a wide range of modern filaments
- Operating temperature up to 300°C: The hotend is designed to operate at temperatures up to 300°C, making it compatible with a wide range of filaments, including those requiring higher temperatures
Leak-proof nozzle and safe replacement without heating
The FlowTech™ printhead eliminates the problem of filament leakage by integrating a brass nozzle with a thermal spacer into a single, factory-sealed unit. This ensures that no leaks will disrupt the printing process . Furthermore, the innovative design allows for quick nozzle replacement without the need for warming up – it can be done one-handed, without the need for force and without the risk of burns.
High material flow and wear resistance
The cylindrical ceramic heater used in the hotend and the 28.6 mm long melting zone allow for high flow efficiency - crucial for fast printing . The all-metal construction (including nickel-plated copper core and titanium screws) ensures longevity and resistance to damage . Each hotend is tested in a full heating cycle, which guarantees reliable operation.

The head eliminates typical problems associated with leaks, complicated servicing and poor thermal efficiency.
Practical applications
The FlowTech™ hotend is suitable for a wide range of applications, from amateur 3D projects to advanced prototype printing in professional workshops. Thanks to its modern design, it is particularly useful for printing complex components where precision and precision are key . It is ideal for use with materials requiring a higher melting point, such as PETG . Furthermore, the ease of changing the nozzle without the risk of burns makes it an excellent option for 3D printing novices as well.
