Reliable for our lab printers
We bought several of these for our office 3D printing farm. They have held up well under continuous use with PLA and PETG. Consistent quality across all units we purchased.

Works great after calibration
The parts feel sturdy. I had to re-run the first layer calibration after swapping the extruder head, but once done, the print quality is fantastic. Instructions could be slightly more detailed for beginners.

High quality machining
Impressed by the tolerance levels. The threads on the nozzle and throat align perfectly without cross-threading. Heating is uniform, and no cold pulls have occurred since installation.

Restored my printer to life
My old heatbreak was clogged beyond repair. This FYSETC kit was easy to install and got my printer running again within an hour. The included silicone sock fits snugly and helps with temperature stability.

Perfect fit for my MK3S+
This kit replaced my worn-out hotend perfectly. The machining quality on the heater block is excellent, and the thermistor reads temperatures accurately right out of the box. My prints are back to being crisp and detailed.

Good value, minor assembly tip
Great components for the price. The nozzle seats well in the throat. Just make sure to tighten everything while the hotend is heated to about 200C to prevent leaks later. Otherwise, a solid upgrade kit.
Q: Is this kit compatible with the original Prusa i3 MK3 (non-S version)?
A: Yes, this kit is compatible with the original MK3, MK3S, and MK3S+ models as they share the same E3D V6 style hotend architecture.
Q: What is the maximum temperature rating for the included thermistor?
A: The included 100K NTC thermistor is rated for standard printing temperatures up to 300°C, suitable for PLA, PETG, ABS, and ASA.
Q: Do I need to update my firmware after installing this kit?
A: Generally, no firmware update is required as this is a direct hardware replacement with standard specifications. However, always ensure your PID settings are calibrated for best results.
Q: Does this come with a silicone sock for the heater block?
A: Yes, the package includes a high-temperature silicone sock to help maintain consistent heating and protect the block.
Q: Is the nozzle made of brass or hardened steel?
A: The standard kit comes with a brass nozzle. If you require a hardened steel nozzle for abrasive filaments, please check our specific variant listings.
