Nozzle 0.8 mm for E3D, compatible with 1.75 mm filament

Nozzle 0.8 mm for E3D, compatible with 1.75 mm filament is a replacement extrusion tip engineered for E3D-style hotends. It increases the extrusion diameter to 0.8 mm, enabling higher flow rates and thicker layers compared with standard smaller nozzles. This nozzle is intended for use where speed, stronger layer bonding and reduced print times are priorities, while fine surface detail is less important. The part is designed for straightforward installation on E3D-compatible hotends; final material and thread compatibility depend on the specific hotend assembly used.

Advantages

The larger 0.8 mm orifice delivers greater volumetric flow, reducing print time on large parts and enabling faster prototyping cycles. Thicker extrusions improve interlayer adhesion for structural prints and functional components. Because filament passes through a larger opening, clogs are less frequent with abrasive or filled filaments compared to very fine nozzles. The simple, standard geometry ensures compatibility with a wide range of E3D-style hotends and straightforward replacement during routine maintenance.

Suitable for

• Rapid prototyping where speed is prioritised over fine surface detail
• Printing structural or load-bearing parts with improved layer adhesion
• Low-detail functional models, jigs and fixtures
• Abrasive or composite filaments where a larger nozzle reduces clogging

Key specifications

• Nozzle diameter: 0.8 mm orifice for extrusion
• Filament compatibility: 1.75 mm filament
• Intended hotend family: E3D-style replaceable nozzle systems
• Function: designed for higher volumetric flow and thicker layer heights

How to use

Allow the hotend to reach an appropriate temperature for the filament in use, then carefully remove the existing nozzle following your hotend manufacturer’s guidance. Screw the 0.8 mm nozzle into the heater block until snug and perform a final tightening at printing temperature if recommended by the hotend instructions to ensure a secure thermal and mechanical fit. Adjust slicer settings to account for the larger nozzle: increase nozzle diameter to 0.8 mm, set an appropriate layer height (commonly 40–80% of nozzle diameter), and raise extrusion multiplier or flow rate as needed. Test print a calibration object and fine-tune retraction and print speeds for optimal results.

Usage recommendations

Use coarser layer heights and wider extrusion widths for faster prints and stronger parts. Increase print temperature slightly for improved layer bonding with dense filaments, and reduce retraction distance to minimise stringing. When switching from a smaller nozzle, recalibrate extrusion steps and review slicer profiles to match the 0.8 mm geometry.
