Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Dual-Wavelength, Two-Photon Printing for High Resolution, Multi-Material 3D Structure Manufacturing.
Background:
Two photon polymerization (2PP) is a direct laser writing 3D printing method capable of printing submicron features with high accuracy. It uses a high numerical aperture objective to focus femtosecond lasers pulses into a diffraction-limited spot, where two-photon polymerization is activated inside a spatially confined voxel. High resolution 3D printing is achieved by scanning this voxel in space. Typically, 2PP relies on free radical polymerization triggered by photoinitiation. However, the ability to use multiple wavelength laser pulses to achieve orthogonal multi material chemistry and enhance resolution via advanced beam shaping has yet to be achieved.
Description:
LLNL inventors have developed a new multi-wavelength laser scanning system for use in two-photon printing. By integrating multiple laser beams with various choices of wavelengths, the invention provides a new pathway to fabricating a multi-material 3D structure in a single vat process while achieving increased printing resolution beyond diffraction limit. The technology uses multiple femtosecond laser beams with different wavelengths coaxially aligned through a dichromic mirror to produce spatially overlapped voxels at the image plane of the high refractive index objective lens. A substrate moves in three-axis relative to the voxels by an integrated three-axis motorized linear stage enabling augmented large scale 3D printing by either stitching or simultaneous motion control of a galvo mirror scanner and linear stages.
