Abstract
In this work, we discuss our findings on dependence of the line segment length of protein printed by femtosecond laser direct write (fs-LDW) using pure protein precursor on pulse energy and number of scans. Two-photon absorption nature of fs-LDW offers high fabrication resolution and flexible 3D writing capability to be advantageous over other 3D printing techniques [1]. Amongst feasible materials, protein is a promising candidate for various biomimetic and biomedical applications [2]. Importantly, fs-LDW using a pure protein precursor may provide high-grade biocompatibility [3].
