The PROTOPRINT nozzle is based on the common length of nozzles you use, but significantly improved. Absolutely accurate and precise nozzles are made in the Czech Republic from durable copper alloy, which is then provided with special surface treatments to achieve maximum quality.


After production, the copper nozzles are carefully inspected and taken to further processing in the form of an industrial nickel-plating bath, where the pores of the material are closed. As a final step, a special type of DLC coating is applied in an inert environment which guarantees perfect slip, easy maintenance and prolongs the life of the component.


The production process is carried out from the beginning to the end in the Czech Republic and each phase takes place in a different production or industrial plant due to the complexity of processes and surface applications. The result is first-class quality.

Product detailed description

Universal nozzle for versatile use

Universal size and Unique Design

DURABLACK nozzles with a length of 12.5mm and an M6 thread are compatible with most of the common used hot-ends on the global market. They excel in properties, durability, ability to print up to 500°C and, last but not least the appearance caused by the production process. The tip of the nozzle is designed to reduce material draw and ensure optimal ironing.

Lightning heat transfer and Durable surface

Perfect Conductivity & Resistance

By using an industrial copper alloy, the nozzle achieves a thermal conductivity of 330 W/mK, which is many times more than commonly used materials such as brass or hardened steels. The result is faster printing thanks to better energy transfer to the material, less energy required to heat up, and therefore lower consumption. Durability is ensured by industrial double coating.

Nickel coating and Ultra-hard layer

One Nozzle, Two Coatings

Double coating with Nickel base layer and ultra-hard outer layer. The layer reach a microhardness of over 5000 HV (>9.5 Mohs) due to the presence of sp3 bonds within the range of 80 - 90%. The smooth and extremely hard coating secure wear-resistance. Thanks to its very low coefficient of friction and low tendency for the material to stick, this nozzle offers an excellent choice for printing materials that tend to stick as well as highly abrasive materials.
