Ultimaker’s CC 0.6 mm Print Core enables you to print using abrasive materials on your Ultimaker S3 or S5 3D printer. This new print core contains a highly wear-resistant hardened steel nozzle that has a 1,000 hour life span, which equates to approximately 10 kg of carbon fiber-filled material. Now you can safely print with filaments containing metal or carbon fiber on your Ultimaker S3 or S5, thus further increasing its range of practical applications.
