Overcoming a major manufacturing constraint

Additive manufacturing (AM) using two-photon polymerization lithography (TPP) has increased in usage in industry and research. Currently, a major constraint of TPP in general and specifically of the material IP-Q (Nanoscribe GmbH, Germany) is the users’ limited access to knowledge about material properties. Due to the nature of the process, the elastic properties in particular depend not only on the utilized material but also on structure size, process, and fabrication parameters. For example, before research recently published in the Journal of Optical Microsystems, no degree of conversion (DC) and Young’s modulus (E) values for IP-Q had been reported.
