Installing print cores on S-line printers


Ultimaker S-line printers use two print cores in the print head, which are interchangeable. There are different types of print cores:

  • Type AA: for printing build materials and Ultimaker Breakaway material
  • Type BB: for printing water-soluble support material
  • Type CC: for printing composite materials
  • Type DD: for printing ceramic support material (in combination with the Metal Expansion Kit)

The print cores contain information on a small chip, so that the printer always knows which print cores are installed and which materials can be used with this print core. Learn more about print cores here.

Install the second print core

Each Ultimaker S3 and Ultimaker S5 comes with two print cores AA 0.4 (one is already installed in print head slot 1) and one print core BB 0.4. This means that it is possible to print with two build materials or with a build and support material. During the welcome setup, the second print core must be installed. Go to Print core 2, select Start, and follow the steps on the display.

  1. Open the glass door(s) of the printer. 
  2. Next, open the print head fan bracket and press Confirm.
  3. Install the second print core (BB 0.4) in print head slot 2 by squeezing the levers of the print core and sliding it into the print head until you hear a click.
  4. Carefully close the print head fan bracket and Confirm to proceed with the welcome setup.

Caution: Do not touch the contact points on the back of the print core with your fingers.

Tip: Make sure you keep the print core completely vertical while installing it so it will smoothly slide into the print head.
