Features
- Compatible Printers: Specifically designed for Anycubic Kobra S1/Combo/ACE Pro FDM 3D printers, this 0.4mm brass hotend kit features an all-metal construction that provides exceptional high-temperature resistance, withstanding temperatures up to 320C. It enables high-speed printing, supporting speeds of up to 600 mm/s, enabling you to achieve rapid and high-quality prints in just 15 minutes.
- Package Included: 2 set 0.4mm Brass hotend kit+2 pcs extra silicone cover+2pcs 0.4mm Brass nozzle. Installation is simple, just remove the old hot end and install a new one, you can start 3D printing immediately. (The hot end kit for Anycubic Kobra S1/Kobra S1 Combo assembly extruder has been pre-assembled.)
- Smooth output: The hot end kit nozzle is made of high-quality brass, which has fast thermal conductivity and can effectively transfer heat from the heater block to the nozzle tip. This ensures that the molten filament maintains the optimal temperature for smooth extrusion, resulting in layer thickness accuracy within 0.02mm. The all metal throat design further enhances the uniform heating of the print head, promoting smooth flow of filaments through the throat and nozzle. This setting ensures consistency in material extrusion without clogging, making it an ideal choice for continuous high-speed printing.
- Compatible filaments: Tailored for a diverse range of 1.75mm filaments, including PLA, ABS, PETG, TPU, and wood filaments, this all-metal hotend kit stands out as an optimal choice for industrial-level printing requirements. Capable of sustaining a bed temperature of up to 120C, it adeptly tackles the printing demands of high-temperature materials such as ABS and ASA. This ensures a reliable extrusion process in industrial printing projects, meeting the stringent standards for professional print quality.
- Friendly Reminder: Before use, we recommend checking that all parts of the assembled hotend kit are securely tightened, as they may have loosened during transportation. Following the installation of this hotend print head kit, we advise you to recalibrate the hot bed for optimal performance.If you have any questions during installation or use, please feel free to contact us, and we will reply within 24 hours!

** The seller did reach out to me to try and make this right, and are replacing the nozzle for me free or charge. They did not have to reach out and even offered a refund, my views on them have indeed changed now! I will gladly give a new nozzle a test and hopefully I just got a fluke! ** Sadly these seem to be prone to heat creep and I cannot get ahold of the seller. I'm just a few days past the 30 day period and now the .02 has died. Would not buy again.

First order, .2 and .6 worked fine, .4 damaged 1 side of my PEI plate. It was an old plate and still had one good side. figured it was a flook. Asked for an exchange through Amazon, and the new set arrived. First thing I did was to try the .4 nozzle and again, pushed itself out and damaged the otherside my old PEI plate. I am now down a plate and still do not have a .4 nozzle. Returning both sets. Possible issue, PTFE tube not cut long enough or wrong size, causing the melted filament to get between the extruder and tube, and while it fills pushed the extruder, disconnecting it from the filament feeder. I attempted to find a way to contact the seller after the first incident as I just wanted to replace the failing nozzle, but had to do a full return for a replacement attempt.

I didn't realize my new Kobra S1 came with a brass nozzle until we received it. I ordered the set (.4, .6, and .8) and installed the .4. I use lots of abrasiveaterial and so far I've had no issues feeding any of them through this hotend.

Extremely close to OEM, I have 20hrs on one hotend. Prints are smooth handle CF very well. Nylon and PC it struggles with but expected at these temps. Definitely would recommend for the cooler plastics. Have not seen any leakage. All good

As long as you recalibrate for the proper hot end, these work great

The hot ends leak and cause clogging and overheating. The metal tube on top that guides the filament into the hot end popped off. The nozzle leakage filled the silicone cover. The first hot end did not last more than a day. Product arrived looked perfect did not operated correctly and broke and leaked everywhere. Need quality control base on my internet search for other manufacturers.
