In in-process inspection or calibration of a print bed or 3D printed part with a 3D printer, toolpaths defining printing material shells for deposition by a 3D printer are compared to surface profile scans from a range scanner to identify differences between the print bed, instructed deposition and the measured result, permitting pausing or alteration of the toolpaths or printing process.

In some examples, an additive manufacturing process may be operated by a method that includes depositing a plurality of preliminary layers of build material over a build surface and applying thermal energy governed by closed-loop control to heat the preliminary layers. The method includes analyzing a temperature distribution across a layer of the preliminary layers to map the locations of any hot spots relative to the build surface. The method includes selecting a spray pattern to apply a cooling agent to the mapped locations.

A build system is provided with: a build apparatus that performs a build process for forming a build object by supplying build materials to an irradiation area of an energy beam from a supply system while irradiating a target object with the energy beam from an irradiation system; and a change apparatus that is configured to change a relative position between the energy beam and the target object, wherein the build system differentiates a condition of the build process that is performed at a first area of the target object and a condition of the build process that is performed at a second area of the target object.

According to some aspects, calibration techniques are provided that allow an optics module of an additive fabrication device to be installed and operated in a stereolithography device by a user. In particular, the calibration techniques enable the optics module to be calibrated in a way that only depends on the characteristics of the optics module, and not upon any other components of the stereolithography device. As a result, the techniques enable a user of a stereolithography device to remove one optics module and replace it with another, without it being necessary to repair or replace the whole device. In some cases, the calibration techniques may include directing light onto one or more fiducial targets within the stereolithography device and measuring light scattered from said targets.
