1. A manufacturing method comprising:
depositing a layer of material on a build plane;
melting a build region of the layer of material using a heat source that scans across the build region, wherein the heat source generates a weld pool at the layer of material;
monitoring a fixed area of the build region with a first sensor having a fixed field of view;
monitoring the weld pool using a second sensor having a moving field of view that is co-linear with the heat source; and
calibrating, based on a phase change material property of the material, the second sensor with data acquired from the first sensor.
