In Ultimaker Cura a 3D printed model can only be sliced when it has a supported print profile. When there is no compatible profile, it shows an orange or red warning in the "Material" menu and a "Not supported" message in the Profile dropdown menu .
There can be a few reasons why a profile is not supported. To obtain a supported profile, it is important to check
- Dual extrusion combination
- Material - print core combination
- How to print guides for a list of supported profiles
1. Dual extrusion
By default, all profiles on the Ultimaker 3, Ultimaker S3 and Ultimaker S5 are shown as dual extrusion and therefore a combination of two material profiles. When you would like to make a single extrusion print, go to the Extruder 1 or Extruder 2 menu and click on the "Enabled" checkbox to disable this extruder. This is important, because sometimes the print settings are taken from the second extruder, while this is not intended. To list some examples:
- Build plate temperature. The highest build plate temperature of both extruders is chosen
- Initial layer height. The highest initial layer height of both extruders is chosen
- Selection of layer heights. Only mutual layer heights, i.e. layer heights that both materials have a supported profile for, can be chosen. This is also important using dual extrusion with two different print core sizes as can be seen in the picture below
2. Supported material - print core combination
Check that the correct print core and material combination is assigned. Composite (abrasive) materials need to be printed with a CC print core. Water-soluble materials such as PVA require the use of a BB print core. It is important to check this for both extruders.
3. How to print guides
By clicking the question mark picture, a user can check for the Ultimaker materials if a print profile for this material - print core combination is developed. This is for example the case when for specific nozzles or print cores a good quality print profile could not be developed. A list of compatible print profiles can be found on the "How to print" information of the Ultimaker materials. Information about materials in the Materials Alliance Program can be found on the Marketplace.
When creating a custom material, it is important to set the 'material type' to a type known by Ultimaker Cura. Please read this article to learn how to create custom material profiles without issues.
