UltiMaker S3

The UltiMaker S3 is an FDM 3D printer from Ultimaker B.V. with a 230 x 190 x 200 mm build volume.

Calibration

• Verify the correct print core pairing before any calibration print.

Action: Install the desired print cores and confirm that the active nozzles match the material profile you intend to use, especially if you are switching between a standard build-core setup and abrasive/composite work. On the S3, the print-core ecosystem is central to reliability; the machine is designed around swappable cores and material-specific nozzle geometry.

Common defects

• Abrasive-material wear on standard print cores: The S3 is verified as capable of running advanced materials and composites, but the sources explicitly warn that standard brass-based print cores are not the right choice for abrasive filaments without an appropriate wear-resistant alternative.

Symptoms: Gradual under-extrusion, rough perimeters, widened line width variation, or a nozzle that no longer produces the same path width it did earlier in its life.
