Schematic of two-photon polymerization system

Engineers at the Technical University of Vienna have succeeded in running a bioprinter at a speed of one meter/second.  They describe the process as this:  Two‐photon polymerization (2PP) is a lithography‐based 3D printing method allowing the fabrication of 3D structures with sub‐micrometer resolution. This work focuses on the characterization of gelatin–norbornene (Gel–NB) bioinks which enables the embedding of cells via 2PP. The high reactivity of the thiol‐ene system allows 2PP processing of cell‐containing materials at remarkably high scanning speeds (1000 mm s−1) placing this technology in the domain of bioprinting.” MORE
