The present disclosure provides various apparatuses, systems, software, and methods for three-dimensional (3D) printing. The disclosure delineates various optical components of the 3D printing system, their usage, and their optional calibration. The disclosure delineates calibration of one or more components of the 3D printer (e.g., the energy beam).

Optics in three-dimensional printing

Techniques of augmented reality device calibration are disclosed. In some example embodiments, a system calibrates a visual inertial navigation (VIN) camera of a head mounted display (HMD) device with at least one eye camera of the HMD device to generate multi-camera calibration parameters, calibrating the at eye camera(s) with a display module of the HMD to generate display calibration parameters, calibrating the IMU with the VIN camera to generate VIN calibration parameters, and calibrating the IMU to the display module using the multi-camera calibration parameters, the display calibration parameters, and the VIN calibration parameters.
