Can you change out the nozzles on the print core with hardened ones?

Recommended Posts

Hi, JClay,

Ultimaker does not advise attempting to disassemble the Cores, because the double heat break is very fragile.

It's designed to help keep the interior of the tube significantly cooler than the brass and prolong the life of the Core; it does this really well, but by necessity, that makes the thin neck fragile. Attempting to remove the nozzle tip can result in breaking the thin neck on the Core and making it unusable altogether.
