Compatible with 1.75mm filament, it features a 0.4mm nozzle, a powerful 12V cooling fan, and a 3ft PTFE Bowden tube, making it suitable for a variety of materials including ABS, PLA, and PETG. With a maximum temperature of over 230C, this hotend ensures precision and versatility in your printing projects. ## Description This hot end is a replica of the newest, popular V6 hotend, this not only allows you to print extremely high temperature materials like PP/ Polycarbonate and Nylons but also eliminates typical hotend meltdown failures associated with other types of hotends. The latest hotend has a PTFE liner that slides inside the the upper portion of the heat brake, to help prevent misalignment of the filament, which is never subjected to high temperatures so there is no risk of damaging the liner through overheating.

It works as expected and saved me something like $20 for going with a genuine hot end. It comes with enough tubing to plumb an Anet A8 twice, albeit I mounted my extruder motor behind the display screen (may vary depending on where you plan on putting it).I will say, in all honesty, I did not use the heater element and thermistor included. They appear to be equal/higher quality than what came from the manufacturer for my printer, but for me avoiding rewiring the new hot end just to risk that they wouldn't work wasn't worth it. It just made way more sense to remove what I already had and install in this hot end.Only real issue is that the fan is 30mm as opposed to the factory 40mm fan; not a problem, but the cord for this 30mm fan is something like 10 inches long - no where near compatible with the Anet A8's distance requirement. my solution was to print a 30-40mm increaser spacer and just use the factory hot-end cooling fan.All-in-all, I'm very pleased with this purchase. I was hesitant it was going to be cloned garbage, but it works. I still need to unwrap the cord for the thermistor/heating element to make sure it's long enough to work with the printer - if it is, I would probably buy a second one of these just as a back-up.If you're looking to do a conversion like I have but don't want to spend a fortune to be disappointed, I would highly recommend starting here. it works and as a worst-case scenario, if you aren't thrilled with the outcome you can always go back to direct extrusion and you didn't spend a ton of money. ### ⭐⭐⭐ 3.0 out of 5 stars Just so you know what you are getting... *by D***E on Reviewed in the United States on November 11, 2017* This hot-end has a second PTFE liner in the hot zone. This is fine for normal materials, but it will degrade eventually with materials like polycarbonate or nylon. A V6 J-Head, it is not.The plastic fan cowling looked great, but was designed poorly and restricts the airflow. This is easily remedied though with a dremel in a couple minutes.The fan is also complete garbage. It was loud to start with, which was acceptable when it was still moving air. I had it running for a total of three hours before it started not spinning up to full speed and making that 'failed fan bushing noise'.The reason it still gets three stars... It was $12 and the rest of it was perfect.Nozzle was accurately sized.Heater block snugly holds the heater cartridge, and the thermistor is held in place with a screw.Cartridge was correct wattage with good silicone insulation.Thermistor was perfectly in spec.Heat sink, fittings, and tubing were all dimensionally accurate and correct. ### ⭐⭐⭐⭐ 4.0 out of 5 stars good hotend bad thermistor *by W***E on Reviewed in the United States on October 26, 2019* I've purchased two of these hotends at two completely different times. Both had bad thermistors. My take is that if you buy these cheap knockoffs just buy a bunch of thermistors and heating elements. Then at least you will get it to work. As an aside if the hotend is not extruding properly until you raise the temp then it is bad and you should change it. It's happened to me enough. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/45256733-3d-printer-accessories-v6-j-head-hotend-reprap-extruder-1](https://www.desertcart.vn/products/45256733-3d-printer-accessories-v6-j-head-hotend-reprap-extruder-1) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
