Optical scanning for industrial metrology

A method for additive manufacturing, said method comprising:

• forming an object, wherein forming said object comprises depositing fabrication material comprising a build material and a fluorescent material that fluoresces in response to illumination by radiation having a first wavelength;
• carrying out profilometry, wherein carrying out said profilometry comprises illuminating said object with radiation at a first wavelength, sensing fluorescence that results from said illumination, and determining a geometric property of said object based on said fluorescence;
• and
• initiating curing of said material, including illuminating said material with radiation at a second wavelength;
• wherein the method further comprises depositing a support material around a partial formation of the object and detecting a transition between the fabrication material and the support material as a result of a difference between the optical properties of the fabrication material and those of the support material.
