Calibration Patterns

For usage of calibration patterns in the API, see this guide.

Specifications

The position of the print is not aligned to the substrate. The printing process is conducted at room temperature without per-piece print calibrations or measurements. We therefore cannot provide any hard guarantees on the accuracy, but the following sections will outline what printing accuracy can be expected in general.

Note

Thermal expansion is provided for reference only and is usually irrelevant in practical applications.
