Tungsten Carbide 3D Printer Nozzle (MK10)

This is not a pure tungsten carbide nozzle, and the product description (lifted wholesale from dyzedesign.com) is incorrect. This is in fact a Cobalt cemented Tungsten carbide nozzle. This is important to note, Dyze's nozzle is pure TC which does indeed conduct heat very well, almost as good as diamond, with the best heat conductivity know to man.Cobalt cemented TC is between 50% and 75% worse at conducting heat than regular brass nozzles.You will have to raise your printing temperatures significantly to print with this nozzle, I usually print at 190-195 with PLA and was getting terrible first layer and layer adhesion, the green benchy (printed by another purchaser) above shows significant beading on the layers indicating the temperature is too low for proper adhesion.When I pushed my PLA temperature up to 220 (225 for ceramic and carbon fiber for which I purchased this nozzle) this fixed all my woes, and I can now print strong dimensionally accurate parts again.If you expect to double your print speed as per the Dyze nozzle, this is not for you, buy the genuine article and pay the premium for the vastly increased machining cost required to work pure TC. If you simply want a hard wearing nozzle for abrasive materials, this one will outperform ruby nozzles with terrible heat transmission, and last longer than your printer.Please note: Amazon is full of Chinese Co-TC nozzles that have also stolen the Dyze product description, one look at the bright silver Dyze TC insert (its impossible to machine pure TC threads, requiring multi-part construction) compared to the one piece dull black of Co-TC shown here will inform you these are significantly different materials with different heat properties. Once your prints are dialed in with the correct temperature this nozzle will print as well as your stock brass.

It is a 0.4 mm extrusion nozzle for a 3 D printer. The material from which it is manufactured is Tungsten Carbide, it should therefor be able to work with any and all plastic and abrasive filaments while showing minimal if any wear for a considerable period of use and in any event much longer than Brass, stainless or hardened steel.I have not yet used the nozzle and so cannot state that this is in fact the case. 4 stars because nothing is perfect.

Works well enough, crank up temps by about 10 though

hoping this beauty will outlast the printer , excellent price too.

Only just received this and while time will tell how well it holds up against carbon fibre, it performs beautifully with PLA on a CR-10S with a Micro Swiss hot end.
