A 0.8mm MK8 hardened steel nozzle is a component used in the field of 3D printing. It is a replaceable part that is fitted to the print head of a 3D printer and is responsible for dispensing melted plastic filament to build up a 3D object layer by layer.

The MK8 refers to the standard model number and design of the nozzle, which is a common type used in many 3D printers. The 0.8mm diameter of the nozzle tip is the size of the orifice through which the filament is extruded. Hardened steel is a durable and wear-resistant material, making it an ideal choice for nozzles that will come into direct contact with the melted filament during the printing process.

This high-quality hardened steel 0.8mm MK8 nozzle can be used with abrasive and high-temperature materials
