Tungsten carbide nozzle Dyze

Dyze is a company dedicated to the development and manufacture of components for 3D printers. Dyze produces hotends, sensors, nozzles and all kinds of accessories, but specialises in the design of extrusion systems.

Tungsten carbide nozzles are FDM 3D printer nozzles designed for maximum durability and high performance. These nozzles feature a high thermal conductivity steel body and a tungsten carbide tip.

High fluidity with abrasion resistance

Tungsten carbide is a ceramic material widely used in industry. Cutting tools for steel and tool steel are made from this material. Tungsten carbide is also widely used in the mining industry, where it is used as a button insert for rock crushing.

Tungsten carbide has two major advantages in the manufacture of nozzles:

• High performance: The thermal performance of tungsten allows the nozzle tip to be kept at a high temperature. This, together with the design of the interior of the nozzle, allows for improved material flow and thus allows high printing speeds to be used without negatively affecting the quality of the 3D printed part.
• Exceptional strength: Due to its high hardness, tungsten carbide is a material with high wear resistance. This makes it an ideal material for the manufacture of 3D printing nozzles, allowing them to remain in perfect condition even under heavy use. This ensures that both the diameter of the nozzle and the exit plane remain the same dimension.

Increased speed

Dyze tungsten carbide nozzles are nickel plated. This coating improves the sliding properties of the product, allowing the polymer to slide over the surface and preventing it from sticking to the surface.

Thanks to the properties of tungsten carbide and the nickel coating, tungsten carbide nozzles have a material throughput that is increased by up to 80% compared to standard brass nozzles.

High compatibility

The tungsten carbide nozzles allow the user to process everything from PLA to fibre-reinforced polymers. In addition, the nickel coating reduces friction and makes it ideal for flexible filament printing. The maximum working temperature of these nozzles is 500°C, making them compatible even with advanced materials such as PEKK, PEEK or PEI.

In addition, Dyze has developed different versions of the nozzle to extend its compatibility with different 3D printing equipment.

Tungsten carbide nozzles are ideal for all users of FDM 3D printers, especially those working with technical materials or fibre-reinforced materials, allowing them to achieve high performance without the wear and tear of other nozzles.
