Our materials and process team optimizes material profiles for each of our supported print cores and Ultimaker materials. This means that a good balance is found between print aesthetics, mechanical properties, and printing speed. However, some materials show poor extrusion or otherwise exhibit unwanted properties when used with either the 0.25 or 0.8 mm print core. The table below showcases the Ultimaker material compatibility with the different print core sizes.
The experimental combinations that are shown for CPE+, PC and PP have a material profile that can be selected in Ultimaker Cura. However, more complicated prints, with tiny features or a large build plate surface, may show increased warpage or oozing. In these cases, the print core 0.4 is advised.
More information about why a profile is shown as 'Not supported' can be read on this page.
Note: Ultimaker PVA should be printed in combination with a BB 0.4 or BB 0.8 print core. All other Ultimaker materials are recommended to be printed in combination with an AA print core. None of the Ultimaker materials are optimized for the print core CC Red 0.6, since this print core is designed to print composite materials.
