In FDM printing, a body is usually built up by repeatedly traversing a work plane line by line and then shifting the work plane upwards so that a form is created in layers.

The layer thicknesses are between 0.025 and 1.25 mm, depending on the application. Solid and hollow bodies can be manufactured. The wall thicknesses that can be produced for a hollow body are, however, limited due to the process, depending on the 3D printer - e.g. B. to at least 0.2 mm.

When the model is produced in layers, the individual layers combine to form a complex part.
