Microswiss Plated Wear Resistant Heat Break - V6 1.75mm Direct and Bowden HotEnds

Beautifully made. High polished inside. Also bought the Witbot brand heat breaks that are very popular on Amazon and come 5 in a pack, and they had burrs inside 4 of them and all had rough walls inside. I'm told it is important to have an internally polished heat break. I'm not sure if there really is a big difference yet during usage, but if you want high quality off the bat and don't want to waste time experimenting, get the Micro Swiss. The E3D is $20 and I don't think it has wear resistant plating like the Micro Swiss does. I'll update if I have any new relevant information.

I installed this in my volcano hotend with the Micro Swiss 0.8mm volcano nozzle. Their stuff is pretty expensive but it seems to last a plenty long time. Print issues that are hard to diagnose are almost always nozzle related and there's enough maintenance on a 3D printer without adding in badly made stuff. Save yourself $100 worth of headache and get these premium quality components. I would replace my nozzles way more often is the price on these was a little lower.

I used this to replace a cheap all-metal heat break. I didn't see any difference. At least I'm resting easy knowing that this part should last longer.

Using a generic "J-Head" V6 style extruder I've dealt with lots of quirks. I fight heat creep when using all metal Heat Breaks, as well as milling issues. With the teflon coated ones I've been pretty much limited to pla. I decided to spring for the MicroSwiss and see what the hub bub was about. I figured I could get 5 generic heat breaks for $10, but this 1 cost me $16? It better be good.All I can say is worth it! it's like butter. My extruder issues have been calmed down from once every 2-3 days to 0.... That's right in the week or 2 I've owned this I haven't a single jam, issue with heat creep or anything else. It really makes me wonder how i've dealt with the jamming mess for so long. So let me get it out there. This heat break has special "Magic Juice".*EDIT* It's been months. Months... without a single jam. I can not believe how wonderful it is to be using the 3d printer like an appliance with zero fiddling. Forget magic juice... this is like a genie in bottle. Want to print without headaches? buy this heatbreak and never look back. I will never own a generic heatbreak again. EVER.

Machining quality is good. Internal bore is super smooth. I used some Arctic MX4 thermal paste on the threads before screwing it into the heatsink. Printing without issue after install for 20+ hours. I'm currently using a .4mm Microswiss hardened steel nozzle which I can also recommend if you're looking to print abrasive materials.Note: Microswiss is a USA company which I try and support when I can and their craftsmanship has been top notch on this heatbreak and the hardened steel nozzle which I mentioned. I purchased both products on Amazon using the 3DMakerworld seller which I've had good experiences with.Printer: Prusa i3MK2Hotend: E3DV6 All Metal

I purchased this heatbreak and was pretty impressed with the quality of the machining.It fit well, but seemed to conduct way too much heat (heat bleed), and jammed almost immediately. I checked my heat sink and my fan, both were fine. I also eliminated retraction. I am using an e3D Nozzle X, a copper heat block, and a genuine e3d heatsink with a 50mm Noctua fan and a custom duct.I was unable to print using this heat break.

Buy it right now, you'll save enormous headache. This works spectacularly. My printer is finally running like a well oiled sewing machine. These have far better machining, the coating is fantastic, and Micro Swiss has a design trick up their sleeves. I've tried every other heatbreak I could get my hands on, even genuine E3D. All the metal heatbreaks have spiral grooves inside and jam within the first few layers, the ones with the teflon inserts disform and jam too. The only other heatbreaks I've had luck with are the gearbest E3D clones.

I bought this after having a clog. I can tell the difference between Micro Swiss heat break and clones. The resistance to filament flow had reduced significantly, and stringing issues are gone for good. It's true what they said about what "you get what you pay for the high-quality part."I use this heat break with p-3d's Apollo Nozzles, Arctic Silver thermal paste, and clone V6 heatsink. This combination gave me phenomenal print quality.
