How to use the DD print core

The print core DD 0.4 is specially designed to print with ceramic support materials on the Ultimaker S5 and Ultimaker S3. Here you can find all information on how to use the print core. Read more about the compatibility on this page.

Installing the DD print core

Installing the DD print core is similar to using any of the other print cores on the Ultimaker S5 and Ultimaker S3. The print core can be changed, loaded, or unloaded via the configuration menu on the printer as described in the Ultimaker S5 manual and Ultimaker S3 manual.


The DD core is designed to print support material and recommended to be installed in print core slot 2.

Note:  The DD 0.4 print core has full compatibility with Ultimaker Cura 5.1 onwards and with S-line firmware version 7.0.4 from the latest channel.


The DD print cores are intended for use on the Ultimaker S5 and Ultimaker S3 only. Although the Ultimaker 3 uses AA and BB print cores, we strongly advise against the use of the DD print core on this printer.

The reason for this is that the feeder of the Ultimaker 3 is not optimized for working with abrasive materials. When using abrasive materials on the Ultimaker 3 – even when a DD print core is installed – the ‘teeth’ of the knurled wheel inside the feeder will erode and cause unreliable material flow and under-extrusion. In the Ultimaker S5 and Ultimaker S3 feeder the knurled wheel is made from a stronger material, which means that it won’t wear when using composite materials.

Please be aware that continuing and using the DD print core with the Ultimaker 3 is at your own risk and not officially supported by Ultimaker.

Caution: The DD print core can be used at a maximum temperature of 265°C. Although models can be sliced at higher temperatures, the print jobs will not be accepted on the printer.

Supported materials

Since the DD print core is specifically designed for use with abrasive materials, it is not supported with any of Ultimaker’s own materials. Ultimaker materials are non-abrasive and can therefore be used with the standard AA or BB print cores. Abrasive materials of third-party material suppliers can however wear out the nozzle of the AA and BB print cores. For this reason, the ceramic support material should be printed with the DD print core.

Because of the open filament system on the Ultimaker S5 and our collaboration with several leading material companies, profiles for various third-party composite materials are provided via the Ultimaker Marketplace.
