CHT - HF Plus
The Trianglelab MZE HF Plus is a melt-zone extender for hotends using a V6-style nozzle interface. It fits between the heater block and nozzle, adding approximately 8mm of heated travel to increase the amount of filament that can be melted before flow-related under-extrusion occurs.
The HF Plus version contains an internal splitter that temporarily separates 1.75mm filament into three thinner paths. This increases the surface area exposed to the heated metal and improves heat transfer towards the centre of the material before the three flows rejoin ahead of the nozzle.

How much can it increase flow?
This version was marketed with an approximate flow increase close to 100% and performance comparable to a Volcano configuration when installed in a standard V6. This should be treated as a commercial reference obtained under specific conditions, not as a guarantee that every printer can double its speed.
The actual result depends on material, temperature, heater power, block, sensor, nozzle, outlet diameter, layer height and cooling. The extender can raise the hotend's thermal flow limit, but it does not increase the machine's acceleration or the extruder's filament-pushing capability.
Hotend compatibility
Trianglelab marketed this family for V6, Dragon, Rapido, CHC, CHC Pro and selected Matrix extruder hotends. Compatibility must be checked for the exact revision: sharing an M6 thread does not guarantee matching depth, sealing surface, silicone sock or available clearance.
Before installation, check:
- An M6 × 1 thread in the heater block's nozzle port.
- Correct contact between the extender and the hotend's internal filament path.
- A V6 nozzle with suitable threaded length and sealing surface.
- Clearance for the extender, nozzle and compatible thermal insulation.
- The final position relative to the mount, part-cooling duct, probe and bed.
On UHF configurations or hotends that already contain an extended melt zone, adding another extender may be unnecessary or create an incompatible geometry. Components should not be combined solely because they share a thread.
3D-printer compatibility
It can be used on VORON 2.4, VORON Trident and other printers fitted with a compatible hotend, provided the toolhead can accommodate the additional length. On Creality Ender 3, CR-10, Prusa and similar machines, compatibility depends on the installed hotend rather than the printer name: a V6 conversion or adapted toolhead is normally required.
The manufacturer's example shows an approximate total height of 70.8mm for a standard V6 with the extender installed. The nozzle sits roughly 8mm lower, so the cooling duct, mount, probe offset and Z limit may need to be changed.
Safe installation
- Unload filament and remove the nozzle using the hotend manufacturer's procedure.
- Allow the assembly to cool and disconnect the printer before handling the block or wiring.
- Check that threads and sealing surfaces are clean and undamaged.
- Thread the extender without forcing it and install a compatible V6 nozzle.
- Hold the parts with suitable tools and perform the final hot tightening procedure specified for the hotend, without transferring force to the heatbreak or wiring.
- After cooling, inspect the assembly and check for material leakage during the first heating cycles.
The seal is produced by internal contact between components, not by tightening the nozzle against the outer face of the heater block. If a part reaches an external stop before closing the internal filament path, do not continue assembly.
Adjustments after installation
- Reset the Z offset and verify probe position.
- Check that the part-cooling duct does not sit below the nozzle.
- Run a new hotend PID calibration.
- Measure maximum volumetric flow again through progressive testing.
- Review slicer temperature, retraction and flow settings.
- Recalibrate Marlin Linear Advance, Klipper Pressure Advance or RepRapFirmware pressure advance if they were tuned for the previous configuration.
Useful speed gains should be obtained by gradually increasing the volumetric-flow limit while monitoring temperature and extrusion quality. Do not simply double the print-profile speed.
Filled filaments and maintenance
The three-channel splitter increases thermal surface area, but also creates a more complex internal geometry. Fibre-filled, large-particle or specially loaded filaments may require additional care and a wear-resistant nozzle. If a blockage occurs, cleaning can be more difficult than with a conventional straight path.
