heatbreak type

I have to change the heatbreak of my MK3S. So I would like to know what kind of heatbreak is best to print PLA, PETG and some ABS? ptfe lining, full metal, titanium, etc...

RE: heatbreak type

You should stick with a full metal heatbreak. Stainless steel should work fine. I would go for the standard heatbreak by e3d:

And what do you think about the microswiss heatbreak: https://store.micro-swiss.com/collections/all-metal-thermal-tubes/products/plated-wear-resistant-thermal-tube-for-e3d-v6-hotend-1-75mm

I have no personal experience but haven't heard anything negative. 

I would go for e3d simply because that is what the hotend is made for.

RE: heatbreak type

The MicroSwiss has good reports from some people, but has an odd internal shape that gives me pause for loading and unload.  Almost as much as the Prusa modded E3D.  It's design leaves a step at the heatbreak/nozzle junction.  The nozzle should always be above melt temps, so this is probably okay, but it is different. And a step in the cold zone, which may cause hardships in unloading.

ps: I own one of the MS plated breaks, I was going to try it if dissatisfied with the stock E3D break.  But so far I am extremely happy with the E3D and have no plans to change it.
