High Temperature All Metal Bimetal Heatbreak Plated Copper Nozzle Heater Block Upgrade Kit Compatible with Anycubic Vyper Kobra Max/Kobra Plus, I3 Mega, Mega S/Pro Volcano Hotend 3D Printer

I installed this one the first day I received it. Took a bit and it came with thermal grease which was new to me since the vyper doesn't use it at all. Did some research and applied that, installed the .4 nozzle I also ordered from this seller and went to work.Leveled the bed. Came outperfect. Fed filament, also perfect. Printing PLA first, no issue. Next PETG. Also no issue. Went straight to carbon fiber printing after and it's incredible the quality of my prints are better now than before for some reason.I ordered this because my stock heating block kept leaking no matter what I tried. This heat break and block are 10x better they don't require the capricorn tube to feed through the heat break just snug against the lip inside it and that makes installing and printing 100% easier. Like you can't mess it up where as the stock one is stupidly hard to get correct especially if you are new to printing which 99% of vyper purchasers are. I was not but seen the easy printing, auto leveling, and other features a luxury for the priceLong story short love the product. Major upgrade from stock and can print at higher Temps unlock stock. With the tempature Guage hole was a little more snug like stock but still worked fine.Defiantly buying again if I need another

Twotrees discontinue their blu-5 machine and I was left with a weird volcano style hotend that uses their own proprietary heat break and nozzle (short nozzle, instead of the typical long nozzle you would expect in a volcano style hot end). I’ve tried different nozzle size which lead to frequent clogging it didn’t fit. I found this kit online and wanted to give it a try. The bimetal heatbreak fits perfectly and now I can print petg again without having to worry about the Bowden breaking down due to high temps.

Was really excited to try this out. Installed it easily enough, quality seemed good, but was having trouble feeding filament through. Extruder was grinding against the filament, seemed like there was a blockage somewhere in the hotend.Pulled it all apart again and a closer inspection of the heatbreak revealed the problem. The heat block end of the heatbreak is almost half obstructed by some sort of defect into the channel. Either some blob or chunk of metal.Disappointed.

So far it's been right. Have had a slight feed issue and had the nozzle loosen from the heat break out of nowhere and cause leak issues. Was easy fix. Will update if problems persist

fast service. nice stuff.

Fit well on my printer. So far no issues

Works very well

The thermistor goes in fine but the screw to hold it in goes in the front of the block with the stock one. This one goes on the side and will break your wires if not extremely careful
