Plated Wear Resistant HeatBreak - 1.75mm

Microswiss is my go to for all of my hotend items, their nozzles and heatbreaks are second to none in quality and durability

I had purchased a Triangle Labs clone Volcano hot end that worked well enough, but I got a clog one day that I had to disassemble entirely to heat up and push out with a 2mm Allen key. I was worried that I scratched the bore, and decided to to 'upgrade' and buy the Micro Swiss plated heatbreak. It made a HUGE difference. No clogs, everything seems more consistent. I can really recommend this piece if you bought a clone hot end and want to make it as good or better than genuine E3D.

Prusa ships heat breaks with an oversized diameter (compared to standard E3D heat breaks) so they work better with the MMU but that causes heat creep issues that can cause issues with annealing filaments. So, I use these instead and I can print with any filament again.

If you have a Prusa without MMU it works as advertised. If you have an MMU it does not work. The ID is smaller than an E3D and it jams the filament when you try to load it the second time. I put this in about a month ago and it Jams almost every time. When I finally compared it to the E3D and tried to manually push a filament tip through it got jammed. E3D goes straight through. I think when it comes out into the PTFE it cools down to a bigger diameter and when it tries to go back in is when it jams. I have written to Micro-Swiss and waiting for an answer. I am in the process of getting another E3D to see if this fixes my jamming issue which I never had when I had it in originally

Very nice heat break. Makes and a direct replacement for the MK3 E3D heat break. The original got ruined when the aluminum block stripped out the threads and damaged the threads of the E3D heat break. Upgraded to an E3D copper/plated block and this heat break. Also got the MS nozzle with the plating. Thought it would make a good combo.
Now if I can only get the MMU to work.
So far so good.
