Micro Swiss CM2™ - RepRap 1.75 Nozzle - 0.4mm

Harto de la fragilidad del latón y sus atascos, me pasé al acero exterior con interior de aleación de Cobre-Cromo-Zirconio niquelado por electrólisis.(Al menos eso dice el anuncio) Lo cierto es que no ha vuelto a atascarse...

Was a nice upgrade from the standard brass nozzle that came with printer

Great thermal conductivity with great wear resistance at a reasonable price. My favorite nozzle ever. The only issue is that it is about .6mm longer compared to standard e3d nozzles, so you have to be careful recallibraiting Z offset.

Finally got some Carbon fiber filament to test this with and it printed beautifully. Zero issues. I've purchased numerous Micro Swiss products over the years and they never disappoint. I tested with Carbon Fiber PLA, PLA, PLA+, PETG and soon some ABS but all the other printed with no issues. Make sure to perform a PID tune and then you're all set. Thanks for another great product Micro Swiss. Sorry it took so long to review but I wanted to see how it did with abrasive filaments. Keep up the great work!

Notice: This product was received at no charge as part of the Amazon Vine program; however, the review contains my honest and unbiased opinion.Let me begin by expressing that I have experience with several MicroSwiss products, and in each instance, the product has stood out for its exceptional build quality. Therefore, I eagerly accepted the opportunity to review one of their products.The standout feature of this product is the hardened tip integrated into a copper core nozzle. Essentially, this design promises the heat stability of copper combined with the wear resistance of a hardened nozzle. I must admit that I seldom print abrasive materials, so my interest in this product wasn't initially geared toward that use case. Nevertheless, the prospect of not having to change the nozzle when the need arises to print abrasives appealed to me.My primary interest was piqued by the fact that I have a Voron TAP on my printer, which utilizes the nozzle itself as the Z endstop and offset. Using the nozzle as a probe presents two potential issues. The first is the risk of premature nozzle wear, a concern that, to date, I haven't encountered. However, it's reassuring to know that this nozzle should be resistant to such wear. The second potential issue is that burned-on filament could potentially skew the nozzle probe measurement accuracy. Consequently, I was curious to test the nano non-stick coating to assess its effectiveness in preventing plastic buildup.In a deliberate test, I obstructed the nozzle to create a blob of plastic, then dislodged the blob to check if filament had adhered to the nozzle. I subsequently increased the nozzle temperature to the maximum (275C) and let it sit for an hour. While still hot, I brushed the nozzle with a brass brush, and the results were immaculate. I repeated the test but allowed the nozzle to cool to room temperature before brushing, and once again, it cleaned up spotlessly.The remaining question is whether it represents good value. It's a challenging assessment since nozzles are typically inexpensive, and it's hard to justify spending more than the few bucks you'd pay for a typical brass nozzle. The combination of a temperature-stable nozzle with hardened steel durability and an excellent non-stick coating should enhance its usability and longevity, thereby adding value in my opinion.
