Can a Titanium heatbreak be used in a Prusa printer?

It seems that heatbreaks for Prusa Mk2/Mk3 hotends (PRUSA-BREAK-175) are somehow different from the standard (V6-175-BREAK). Does this mean that the upgrade Titanium heatbreaks (V6-175-BREAK-TI) will not fit a Prusa hotend?

Is this a good question?

Es-ce que le heatbreak en titanium peu être utilisé pour des température au dessus de 250 degree? Sinon qu'elle sont les composant que je dois acheter pour cela avec ma Mk3, Merci


Yes, the Prusa specific Heatbreak can be used above 250°C, like the stainless steel heatbreak it can be used up to 280°C in standard HotEnd setups and with a plated copper heater block, PT100 and plated copper, Hardened steel or Nozzle X you can use them up to 450°C.

Hi Tony,

The Prusa specific heatbreaks have a slightly different internal geometry to help aid retraction with the MMU and MMU2. For single material printing the Titanium heatbreak is 100% compatible, however if you are using either the MMU or MMU2 then we would recommend using the Prusa specific heat break.

Since when is the Prusa specific heatbreak included in Prusa Printers?

I upgraded my 2016 MK2 to MK2.5S with MMU2S. The heatbreak stayed the same. How can I see which one I have?


@kurt I would recommend speaking to Prusa directly in regards to this.
