What the E3D Revo High Flow Brass Nozzle 1.2mm Does

The E3D Brass Revo High Flow Nozzle 1.75mm-1.2mm is a brass nozzle for the E3D Revo ecosystem that increases material throughput for larger, faster FDM printing. Its 1.2mm nozzle diameter is intended for printers using 1.75mm filament and for users who want wider extrusion paths than a standard nozzle can provide.

This Revo high flow nozzle is built for high-volume extrusion where print speed, thicker lines, and efficient large-part production matter more than very fine surface detail. Brass construction also makes it a practical choice for common non-abrasive filaments.

Key Features of the Revo High Flow 1.2mm Nozzle

• 1.2mm nozzle diameter for high-output printing: Supports wide extrusion widths and larger layer strategies for fast builds and substantial wall sections.
• High flow design: Made for improved melt throughput compared with standard-flow nozzles, helping compatible Revo setups sustain higher material demand.
• Designed for 1.75mm filament: Matches the most common desktop FDM filament format used across hobby, prosumer, and workshop machines.
• Brass nozzle construction: Brass offers strong thermal conductivity for stable heating with standard non-abrasive materials.
• Revo system fitment: Built specifically for E3D Revo hotends, making it part of the Revo nozzle platform rather than a generic threaded nozzle format.

When a 1.2mm High Flow Nozzle Makes Sense

A nozzle in this size range is useful when part strength, wall thickness, and shorter production time matter more than fine cosmetic detail. Wider extrusion can also help produce large-format prototypes, jigs, fixtures, housings, and workshop parts more efficiently.

The E3D Revo High Flow Brass Nozzle 1.2mm is also a practical option for users tuning a printer for larger layer heights and broader line widths. In those workflows, the nozzle supports high material output while remaining suitable for everyday non-abrasive filament use.

Typical Use Cases for Large-Nozzle FDM Printing

• Functional parts: Useful for brackets, guards, spacers, and utility components where speed and durability are prioritised over fine detail.
• Large prototypes: Helps reduce print time on concept models, enclosures, and form checks for design iteration.
• Workshop and farm production: Suitable for repeatable larger-format prints where throughput is a key requirement.
• Thick-wall applications: Supports print strategies that rely on substantial extrusion lines for robust outer walls and fast infill coverage.

Material and Practical Use Notes

Brass nozzles are commonly chosen for standard, non-abrasive filaments because they heat efficiently and are widely compatible with everyday printing materials. For abrasive composites such as carbon fibre, glow, glass-filled, or metal-filled filaments, a harder nozzle material is generally the better choice.

Because this is a 1.2mm high flow nozzle, successful printing also depends on slicer tuning, adequate heater performance, and part cooling matched to the print goal. Larger nozzles usually require different line width, layer height, and flow settings than smaller-detail nozzle setups.
