Determining optimal laser power and scanning speed. A) Representative image of undesirable, delaminated two-photon polymerized structures. B-C) Width of stars created using the fastest scanning speed that did not result in edge artifacts for 300 g/mol (B) and 900 g/mol (C) PCLTA at three prepolymer concentrations, each with 3 wt% photoinitiator. Each point represents the mean (n = 3), while error bars represent the standard deviation and the dotted line represents modeled star pointtopoint distance.
