all metal hot end for UM3

Posted (edited) · all metal hot end for UM3

Well, if you ask me there is only one single reason to go all-metal, and that is to print with plastics in the 300C+ range, so more or less PEI and PEEK, and for those you more or less need a enclosed heated chamber to print.

For everything else... the current Core design is way better.

    Brass is a metal but the bottom of the brass nozzle will wear out quickly if you print abrasive filaments.  You can however get a steel nozzle for UM3 cores.  Since you are in canada you should get it at my store: thegr5store.com.
