Which heatbreak is better? Request for opinions!  

RE: Which heatbreak is better? Request for opinions!

I don't think it is that simple as there being a "best" heatbreak. I've been reading this forum for years and seen reports both good and bad for all of them. I don't have experience with any of the third party ones, but if assembled and set up correctly per the exact Prusa instructions, the stock Prusa one has worked for me for almost three years now for PETG, ASA, PC Blend and TPU. Each filament brand and color is different, so I am sure that one heatbreak or another might be better for one filament while being worse for another. The Prusa seems to be "good enough" for everything I have tried.

I did have to completely rebuild my hot end when it got clogged and gummed up with cooked on filament. I followed the assembly instructions to the letter, and they have changed over the years.

Regards,

I myself only use the original Prusa accessories.

Perhaps that is not the best hotend heatbreak,

but it will ultimately ensure that you will encounter the fewest problems with replacement.

So I say go for the original Prusa.

I'm a huge fan of titanium heatbreaks. Titanium has lower thermal conductivity. So when in direct comparison to a steal heatbreak, one can get away with less cooling of the hotend, thus reducing fan noise. 

Don't have any personal experience with the above linked model though.
