Ultimaker Print Core DD 0.4mm (9550): The print core DD 0.4 is specially designed for printing support interface layers in combination with metal materials on S series printers. This print core is optimised to withstand abrasive materials, such as the ceramic support layer filament used for metal FFF printing.
The DD print cores are used for Ultrafuse® Support Layer material. This print core is included in the UltiMaker Metal Expansion Kit and can also be purchased separately. Requires UltiMaker Cura version 5.1 or later, and S series firmware 7.0.4 or later.

The DD print core is compatible with S series printers, including the UltiMaker S3, UltiMaker S5, and UltiMaker S7. These printers are prepared for printing abrasive materials; the knurled wheels in the S series feeders are made of a hard material with a special coating to minimise wear due to composite materials.
Note that the DD core is specifically intended for Ultrafuse® Support Layer material. This is NOT supported in combination with a Material Station.
It is recommended to use an Air Manager while printing Ultrafuse® 17-4PH and Ultrafuse® Support Layer materials. The Air Manager is an integrated component of the UltiMaker S7 and an optional add-on for the UltiMaker S5.
MAINTENANCE:
Due to the material properties of Ultrafuse® Support Layer, more frequent maintenance is required for the DD core than for other print cores. For the DD core, it is recommended to clean it using the hot and cold pull method after each print, unless another print job is started again immediately. Always clean the print core if it will not be used again for a longer period of time, or before unloading it from the print head.
