Scientific field guides · 01—06

Follow the light into matter.

A connected guide to two-photon lithography, two-photon polymerization, multiphoton fabrication, direct laser writing, and the models used to reason about them.

01The core processTwo-photon lithographyUnderstand two-photon absorption, photopolymerization, the voxel, scan paths, and development—and how TPL, 2PP, and TPP relate.02The wider familyMultiphoton lithographyPlace two-photon writing inside multiphoton 3D lithography and separate mechanism-specific terms from broader fabrication language.03The umbrella methodDirect laser writingLearn when DLW means two-photon polymerization, when it does not, and why the distinction matters for models and search terminology.04From threshold to transportThe model spaceCompare optical, dose, kinetic, reaction–diffusion, development, mechanical, and calibrated models of the fabrication process.05Every control, intuitivelyParameter atlasTrace all 27 path, light, resin, and development parameters through their expected effects, interactions, and model boundaries.06The exact implementationInside the calculated voxelRead the equations, evidence boundaries, primary references, and explicit limitations of the model running in the browser lab.
