Printcore replacement heater cartridge and pt100 sensor parts

Posted · Printcore replacement heater cartridge and pt100 sensor parts



Just wondering, has anyone ever managed to order a replacement heater cartridge and pt100 for the UM3 printcores? The github page seems to list them as part numbers 1996 and 1997. Just wondering if they are supplied cut to length and have the pin connectors already attached? Also, does anyone know if the 25w heater is the same for the 0.6 and 0.8mm cores?

    Not sure why you want to order a PT100, those are passive components and almost indestructible. These are PT100-B types and when you ensure the dimensions are the same you can order them everywhere for less than the original Ultimaker replacement parts. Then you will have to cut the wires to the desired length yourself.


    Same goes for the heater element.

    Most likely this is the exact same component as used in the UM2. Note that the UM2+ uses a 35W heater, this won't work.


    All printcores use the same 25W heater element (AA, BB, CC cores and all diameters).


    A last note on the heater and PT100 from Ultimaker is that the wires on these components are extra flexible. This because of the movements in the Printcore. Cheaper replacement components will be less flexible and wires can break.

    Hi @CarloK, thanks for the reply and info.


    Unfortunately I had a flooded print head so in taking this apart, the pt100 and heater cables had to be sacrificed. Cleaning up the head and core, I see there is no connector/ferrule, just the wire straight onto the core board so one less thing to worry about.


    Would a Ultimaker reseller be able to actually supply these parts? Would they come to the cut length already with the heat shrink? As you say, if the original wires on the Ultimaker spec are extra flexible, makes sense to stick with those.


    Many thanks,

    I don't know if a reseller has these parts, but you can ask. Perhaps you are lucky and they have a damaged print core where you can get spare parts from.


    Expect minimum EUR20 for the PT100 and EUR15 for the heater cartridge.
    Counting labour costs, professional users will just replace the whole print core and keep the old one for spare parts.

    Since you consider repairing the print core I've the feeling you don't count labour costs. Then you can go for a cheaper UM2 compatible components from a third party supplier. Even with the lower cable quality you will save money over time.
