Department Of Energy Tender

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 Conventional Tpp Platforms. This Novel Approach Significantly Increases Throughput Without Sacrificing Resolution Or Introducing Stitching Errors. advantages/benefits: 1000x Speed Compared To Currently Available Tpp Printers wafer-scale 100 Nm-resolution free Of Stitching Defects potential Applications: using The Fine Resolution Of Submicron Am, The Technology Can Be Used In A Wide Variety Of Fields To Fabricate Functional Micro- And Nanoscale 3d Structures For Photonic Crystals, Micro-optics, Mechanical Metamaterials, Micro Fluidics, Miniaturized Optics, Flexible Micro-electronics, Micro-electromechanical Systems (mems), On-demand 3d Chip Packaging Solutions, Custom Micro-heatsinks For The Next-generation Semiconductor And High-density 3d Optical Memory. Tpp Can Also Be Used To Produce Architected Materialsfor Energy Solutions (e.g., Battery And Co2 Electrolyzer Electrodes) And Biomedical Engineering (e.g., Neural Probes). development Status: current Stage Of Technology Development: Trl ☐ 0-2 ☒ 3-5 ☐ 5-9 llnl Has Filed For Patent Protection On This Invention. u.s.
