Compatibility

V5 & V6 Hotends: Designed for E3D V5, V6, and compatible hotends. <br> UM (Ultimaker) Compatible: Often refers to nozzles designed to fit Ultimaker's specific hotend setup, which frequently uses M6 threaded nozzles.

Material

Brass: The most common and cost-effective material for 3D printer nozzles. Excellent thermal conductivity for consistent extrusion.

Thread Size

M6 Thread: Standard metric M6x1.0 thread for screwing into the hotend's heater block.

Filament Diameter

1.75mm: Specifically designed for use with 1.75mm diameter 3D printer filament. The internal bore ensures proper filament guidance.

Nozzle Diameter (Output Bore)

Common sizes: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm. <br> If "0.2" specifically refers to the nozzle output bore, then it is 0.2mm. <br> This defines the thickness of the extruded plastic line.

Overall Length

V6 Standard: Approximately 12.5mm <br> V5 Standard: Slightly longer, approximately 15mm

Thread Length

Approximately 7.5mm - 8mm (for M6 thread)

Flats (Wrench Size)

Typically 7mm or 6mm wrench flats for tightening.

Key Features

High Thermal Conductivity: Brass quickly transfers heat from the heater block to the filament for smooth melting. <br> Smooth Internal Bore: Reduces friction and prevents clogs. <br> Precise Machining: Ensures accurate extrusion diameter. <br> Easy to Install/Replace: Standard threading allows for quick changes. <br> Cost-Effective: Generally inexpensive, making them suitable for everyday printing and easy replacement.

Disadvantages

Wear: Brass is a soft metal and wears down relatively quickly when printing abrasive filaments (e.g., carbon fiber, glow-in-the-dark, metal-filled). This leads to increased nozzle diameter and reduced print quality over time.

Typical Applications

General purpose 3D printing with non-abrasive filaments like PLA, ABS, PETG, TPU, Nylon.
