Geekcreit® Assembled Aluminum Heating Block Extruder Hot End For 3D Printer 1.75mm MK8 0.4mm Nozzle (1.75mm block extruder hot end)

The 3d printer hotend’s heater block undergoes a massive amount of stresses: thermal stress from the heater, pressure stress from the extruder and tension stress from the nozzle.

This kit makes it easier to replace the heatblock with the cartridge, thermister and nozzle of most Reprap type 3D printers.

Creality 3D CR-X 0.4 MM Hotend Extruder Nozzle (CR-X print nozzle)

These 0.4mm MK8 Nozzles are Creality Original replacement parts designed to fit the Creality CR-X, and are based on the successful MK8 design. They are the standard nozzle size of 0.4mm, which is the same size that comes equipped on many of the modern models since 3mm filament began phasing out. This size offers impressive accuracy without compromising too much on the rate at which 3D Printers lay down the Plastic Filaments – A good balance of speed and quality that is relatively easy to work with compared to larger or smaller nozzles.

While some people enjoy printing with smaller nozzles to ascertain even better quality and printing accuracy, and others choose to use large nozzles for speed-printing models or objects that don’t need to be perfectly accurate, these nozzles offer the best of both worlds. This is why they come as the stock nozzles on so many different models of printers. However, if you are a veteran in 3D Printing, you will understand that each different size nozzle can offer their own benefits
Package includes:

1 x 0.4mm nozzle for CR-X
