Electrical characteristics of the Ultimaker Print Core AA 0.40mm

[Interdisciplinary 0]

Hello,

 

Currently I am trying to use the electronics  printcore AA 0.40mm for a research project. Although I was able to find on the internet some characteristics with the sensor (PT100, I was not able to find any further details on the heating element.

Does anyone know what operating voltage and amps range might be used or what type of heating element it is?

They are 24v printers, so safe guess it’s a 24v heater element

Dear Jasonjason and members,

 

The information seems right. A product description states 24 Volt and a power of 35 Watt:

So 3dsolex cores are 30W.  Ultimaker cores (all the one's I've tested which I think is all of them) are 25W.

 

You can change the heater to a 35W and it will work but it may oscillate a bit unless you also modify the PID values.  I recommend sticking with 25W.

 

They are "ceramic" heaters.  I don't know what that means.  The diameter is an even integral mm.  I forget if it's 2mm, 3mm, or 4mm.

You got the 24Volt part right.  So UM cores are around 24 ohms and 3dsolex cores are around 19 ohms.
