The original Ultimaker 3 & S5 Print Core upgraded to the Hard Core from 3D Solex is the ultimate tuning for your Ultimaker 3 and Ultimaker S5.

The Hard Core (AA) from 3D Solex is intended as an exchange for Ultimaker's Print Core (AA).

The red anodized aluminium radiator makes the Hard Core easily recognizable.
The heating cartridge and the temperature sensor also have better contact with the block.

The advantages of the Hard Core of 3D Solex:

  • Easy nozzle change
  • Different nozzle types and diameters
  • Less mass - the Hard Core is lighter than the original Print Core
  • Improved temperature distribution

Included Hard Core Pro 2:

  • Hard Core AA
  • 0.40 & 0.80 mm hard core nozzles
  • Tool for nozzle change

Hard Core Six Pro 4 included:

  • Hard Core AA
  • 0.25 & 0.40 & 0.60 & 0.80 mm hard core nozzles
  • Tool for nozzle change

Included Hard Core Six Pro 7:

  • Hard Core AA
  • 0.25 & 2x0.40 "ICE" & 0.50mm "ICE" & 0.60 & 0.80 & 1.00mm Hard Core Nozzles
  • Tool for nozzle change

More information

After replacing the Print Core we recommend a recalibration of the 3D printer.
