Diamondback Nozzles – MK8 Compatible – Polycrystalline Solid Diamond Tip 3D Printer Nozzles, Improved Extrusion, Any Filament, Long Life, Wear Resistant, Layer Adhesion, USA Made (0.4mm)

This nozzle is awesome but can throw you for a loop in one regard. Much like steel nozzles it can change the temp needed to print but unlike steel you wont see a potential increase in temp but a potential decrease in it. Definitely worth the money in my opinion

I got this a month ago and have printed non stop with it. So far it has worked perfectly. Taulman CF nylon goes through it like a dream. Ive also printed a lot of PLA + and some TPU (90A and 95A). I havent had any clogging issues. Ive had a couple of different Micro Swiss hardened nozzles on two different printers but always had issues, probably due to heating. The Diamondback nozzle fixes that issue and I can actually print an average of 5 degrees cooler. This nozzle is on a CR10S with a MicroSwiss NG Direct drive and all metal hot end. Despite the cost I would buy this nozzle again, although I would hopefully be able to time it with a black Friday sale.
