- Machined Titanium Heatbreak
- Made from TC4 Titanium Alloy
- Polished inside bore
- Works with our Tough Hotend, E3D V6, and Clone E3D V6 1.75mm Hotends
- Check to make sure your heatbreak matches the appearance of ours
- M7 Top Threads
- M6 Bottom (heatblock side)
- Length: ~22mm
- Lower Thermal Conductivity for better retraction and less heat creep
- Inner Diameter: 4mm at the top, 1.85mm about 5-10mm deep. This holds the PTFE tube in the top, but does not allow it to go all the way through.
- Outer Diameter: 6mm (top smooth section), 7mm (middle threading), 3mm (throat), 6mm (bottom threading)
- Lengths: 5mm (top smooth section), 10mm (threading), 2mm (throat), 5mm (threading), ~22mm (overall)
- Note: Dimensions may vary slightly due to manufacturing tolerances. This does not affect the use of the product.
- Heatbreaks are delicate parts.
- Never tighten your nozzle without holding the heater block with pliers. Doing it without can break the transition zone (the thinnest part).
- Nozzle crashes can also bend the heatbreak. If your heatbreak is bent in a nozzle crash slowly try to bend it back to the original position.
- Our warranty does not cover damage to the heatbreak from over-tightening or nozzle crashes, only defects in the product itself.
Tips for Using This Heatbreak
Installation directions: Heatbreak Installation Information
Oil it – We recommend if you are getting jamming with PLA (this can happen with ALL METAL heatbreaks from any manufacturer) to print a filament oiler. Like this one: https://www.thingiverse.com/thing:492067. Stuff it with a sponge or fiber then lightly wet with CANOLA oil. This will oil the filament path and keep the PLA from sticking to the heatbreak on a longer retract. After using this for about a month or two your heatbreak should have a nice “seasoning” on the inside and use of an oiler will be needed less or not at all.
Lower Retraction – Stick to under 3mm retractions. All metals will need less retraction than a PTFE lined hotend. 25-50mm/s depending on your machine setup. Wipe is recommended (2-5mm).
Thermal Paste (Optional, but recommended) – When installing the heartbreak you can apply thermal paste/grease (like what is used on computer CPUs) to the outside that inserts into the heatsink before installation. This will improve thermal transfer from the heatbreak to the heatsink.
