Description

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 Metalens-enabled TPP printing.



Background:

LLNL has been at the forefront in developing two-photon polymerization (TPP) additive manufacturing (AM) method. In 2018, LLNL was a recipient of a Federal Laboratory Consortium (FLC) award for their development of FemtoProWrite, which leverages TPP. TPP is a laser light-directed writing technique in which crosslinking reactions initiated by light lead to a change from liquid to solid within a region that is smaller than the light spot. The method is very high resolution, capable of fabricating micro- and nano-scale features.

However, conventional TPP AM printers have extremely slow printing speeds with limited part size since they utilize a single laser spot approach where the laser is directed through a conventional microscope objective and the 3D printed part is built by scanning within the resin material. There is a market need to maintain the high sub-micron printing resolution offered by TPP, while increasing the throughput and dimensions of the printed components.



Description:

LLNL researchers have developed a parallelized TPP system that combines metalens array and spatial light modulator (SLM) to manipulate the directed laser light, which enables high-volume fabrication of nano-architected structures at wafer-scale. Instead of using a single microscope objective, LLNL-s approach uses an array of metalens that the laser passes through with each metalens being independently controlled via a SLM. This parallelization of printing allows for large scale, high throughput writing of periodic and non-repeating patterns that exceed the capabilities of conventio...
