Two-photon polymerisation system for 3D lithography and micro 3D printing applications

Based on the underlying printing resolution Two-Photon Polymerization (TPP) can be distinguished into 3D Lithography and Micro 3D Printing applications. Both of these fields will be discussed in terms of the requirements on the fabrication process such as exposure strategy, overall resolution and accessible print height among others. Enabling both 3D Lithography and Micro 3D Printing in one TPP laser system imposes certain challenges which will be addressed with solutions being presented.
