Abstract

We show that optical coherence tomography (OCT) is a promising method for in-situ imaging during multi-photon laser printing. OCT measurements can provide access to properties and quality control of 3D printed microarchitectures. Our developed in-situ OCT system is fast and can be directly integrated into an existing multi-photon laser printer. Among demonstrated applications of the developed apparatus are photoresist-homogeneity inspection, evaluation of the polymer refractive index, thickness measurements of printed parts, etc. Obtained OCT reconstructions reveal optical imperfections in the printed specimens and can be compared with targeted 3D computer models.
