Overview

The 3D printer hotend is the business end of FDM 3D printers, responsible for melting plastic from a solid to a molten state.

This is a list of popular all-metal hotends compatible with common toolheads for Voron pritner, Printers for Ants, and other custom 3D printers. Non-standardized, PTFE lined, or proprietary hotends for prebuilt machines shall typically be excluded unless widely adopted and supported by the community.

Disclaimer: The listed flow rates for the hotends are estimated claims and will vary based on test conditions.

Terminology:

• Mounting: How the hotend is attached to the toolhead.
• Length: The total length from the top of the mount to the tip of the nozzle.
• Flow Rate: The max mm^3/s the hotend can flow without extrusion issues.
• Melt Zone: The zone from the top of the heaterblock to the tip of the nozzle.
