UMO Peek Isolator and Aluminium holder

[neotko 1,417]

Hi,

Maybe someone with more know-how could answer this. I'm trying to mount a head holder for the dual extruder magnetic proyect created at http://umforum.ultimaker.com/index.php?/topic/9657-a-different-multi-extrusion-approach-um-tool-printhead-changer/

My question it's... The aluminium part that it's holding the peek isolator. It's aluminium just because that area it's hot or it also plays as heat dissipation ? I ask because my thermal says it goes around 100-120C (the aluminium stays around 30-40) and if I changed it for wood I might be making a big mistake and increase a lot the chances of clogs.

Thanks

Its hot and does aid in some heat dissipation/thermal mass.

Its also fairly easy/cheap to machine and dimensionally stable/corrosion resistant, lightweight, etc...

Wood has no business being around any source of heat. Wood is a big mistake. Unless you like fires.

Seems you are right about the heat. The maximun it can support it's 150C and it losses weight. At 200C it can combust.

Anyone knows somewhere in europe that can CNC two small aluminium holders (exactly the half size of the umo aluminium holder) ?
