Microswiss CM2 MK8 Nozzle for Makerbot, Creality Ender 3, Ender 3 S1, Ender 5, CR-10 Series - Copper Core - M2 Hardened Steel Tip - Superior Thermal Performance - Exceptional Wear Resistance (.4mm)

I love Microswiss nozzles. The quality is much better than the cheap manufacturer's nozzles, resulting in better print quality and better reliability. The CM2 nozzle is particularly well designed and well manufactured. The core of the nozzle is high temperature copper chromium zirconium for excellent thermal transfer. The tip of the nozzle is made of M2 hardened tool steel and coated with a special nonstick nano coating. The nozzle is electroless nickel plated. This is an attention to detail that isn't found in the cheap brass or steel nozzles supplied by any 3D printer manufacturer. The result is a long lasting nozzle that is suitable for any material. The CM2 nozzle conducts heat like a brass nozzle, is more durable when printing abrasive materials such as carbon fiber than a manufacturer's steel nozzle, and the nano coating and nickle plating improve the flow rate and decrease material buildup on the outside of the nozzle. It's easy enough to unscrew an MK8 nozzle and screw in another, but I seldom bother. A 0.6 mm CM2 nozzle is a good choice for almost all prints, abrasive or not. I'd switch to a 0.2 mm nozzle if I needed the best print resolution on a miniature part, and I'd switch to a 0.8 or 1.0 mm nozzle on a large printer if I needed to quickly print a large part, but for almost all of my printing, the 0.6 mm CM2 nozzle produces excellent results in PLA, PETG, PET-CF, ABS, ABS-CF, TPU and TPU-LW. The print quality is more a factor of layer height than nozzle diameter so I get good print quality with 0.2 mm nozzle height for carbon fiber filled materials and as low as 0.125 mm for PLA, PETG or ABS. Stepping up from a 0.4 mm to a 0.6 mm nozzle eliminates the chances of a clog with carbon fiber or glass filled filament but also reduces print time by laying down wider filament widths for fewer walls. The 0.6 mm CM2 nozzle is my Go To nozzle for almost all of my printing.

I use this nozzle for Nylon and it holds up really well. Highly recommended!

Works great for my custom 400mm Ender3, excellent quality as expected from Microswiss. Also a great value for a wear resistance 0.4mm nozzle.

I have multiple printers and I always try to use MicroSwiss nozzles. Yes they are a little more expensive but you can count on the reliability of these nozzles. They are good quality nozzles and very easy to use.

Ender3V2+Solid and consistent prints. Will buy again.

Microswiss is always a good product and why I always go back to them. Makes my prints noticably better

I’ve run about 10 rolls of PLA-CF through it and still going strong with no clogs.

I think it’s worth the extra money.
