What is Two-Photon Grayscale Lithography?
Two-Photon Grayscale Lithography has emerged as a groundbreaking innovation in industrial manufacturing and 3D printing technologies. This advanced technique leverages femtosecond laser pulses to create highly precise three-dimensional structures through an intricate polymerization process. The “grayscale” method further enhances this technology by varying the density of each voxel (volumetric pixel), enabling the production of incredibly detailed and precise 3D structures.
How Does It Work?
The technology operates by focusing a laser onto a specialized polymer material. The material hardens only at the point where two photons simultaneously interact with a molecule. This unique property facilitates the creation of nanoscale precision structures. The grayscale method allows for fine-tuning the density of each voxel on the material, providing unprecedented control over both structural and optical properties.
