Technical report demonstrates sub-100 nm photopolymer 3D printing via two-photon polymerization, highlighting how resin formulation and laser dynamics control nanoscale fabrication.
This white paper covers two-photon polymerization for sub-100 nm photopolymer 3D printing using specialised resins and Fine Tuner systems for VIS-NIR and 1035 nm femtosecond laser platforms. 2PP requires a different formulation logic from standard VPP: two-photon absorption efficiency, laser wavelength, voxel size, writing speed and nanoscale shrinkage dominate the process window.
