Micro Swiss Plated Nozzle for LulzBot TAZ 5, LulzBot Mini, Hexagon Hotend Style (.5mm)

Allow me to go a little more in-depth on this review . . . The nozzle works excellently and does what its supposed to. It is better than stock for flow and clean-up. However, installation is tricky. The one star review who supposedly ruined the hot end obviously cross threaded it from the get go, which is a huge no-no. Even if the nozzle is over tightened, the BRASS nozzle will not likely ruin the STEEL hot end when threaded appropriately. The person may have also not been using a Lulzbot Hexagon hot end, because its very difficult to ruin steel threading with brass threading. The brass threading will almost always strip first. When installing this, be very careful. Tighten slowly and by hand (use some type of heat insulator, like a hot pad) with the hot end set to approximately 165 C. Do not over tighten. When it is snug, do a test print. If it leaks, tighten it just a tad more. Do another test print. If it leaks, tighten it just a tad more. You get the idea. Proceed very slowly and carefully. I did end up having to use a wrench a little bit to keep it from leaking without thread locker. Some people say a thread locker is not required. I say, Resbond 907TS Blue if you want to secure it against leaks while ensuring it doesnt have to be overtightened.

good quality

Ive been using these for over a year now and its a fine product. Ive had no jams, clogs or other nozzle related problems since and it still looks like it just came out of the box. The plating doesnt oxidize so it doesnt mess with the ohmic height sensing (obviously you need to wipe off any excess non-conductive material between prints). I usually print with PLA because its biodegradable and for the most part it does what I want. I also use abrasive carbon fiber, metallic and high temperature filaments from time to time. Ive yet to see the slightest indication any degradation. The price is reasonable, installation is easy so its pretty much a no-brainer upgrade for your Lulzbot.

Just right for most prints
