Ultra high flow hotend for faster extrusion and higher temperature printing

The Phaetus Dragon Hotend (Ultra High Flow) is an all-metal FDM hotend designed to deliver substantially higher melt capacity for demanding print speeds and larger material output. It is suited to users who need more volumetric flow than a standard hotend can provide, while also supporting high-temperature printing applications.

This hotend is built for 1.75 mm filament systems and targets printers used for rapid prototyping, larger nozzle setups, engineering materials, and high-throughput workflows. The all-metal construction also expands material compatibility beyond the limits of PTFE-lined hotends.

Key features of the Dragon Ultra High Flow hotend

• Ultra high flow design: Supports higher extrusion throughput for fast print profiles, large layer heights, and wider extrusion widths.
• All-metal filament path: Handles elevated temperatures and enables use with a broad range of standard and engineering-grade thermoplastics.
• High temperature capability: Rated for operation up to 500°C when installed in a suitable printer setup with compatible electronics and sensing hardware.
• Built for demanding materials: Suitable for common filaments such as PLA and PETG as well as materials like ABS, ASA, nylon, PC, and other high-temperature polymers when the full printer system is appropriately configured.
• Upgrade path for performance-focused printers: Well suited to users increasing print speed, nozzle size, or overall material output.

Where a high-flow 3D printer hotend makes the biggest difference

A high-flow hotend is most useful when a standard melt zone becomes the limiting factor in print speed. That includes large functional parts, high-speed machines, production-style workflows, and print profiles using larger nozzles or thicker layers.

The Phaetus Dragon Ultra High Flow hotend also fits advanced material workflows where elevated extrusion temperatures are required. For users building or upgrading a printer for engineering plastics, faster prototyping, or large-format output, this hotend helps match the thermal side of the printer to the machine's motion and extrusion capabilities.
