The Lawrence Livermore National Laboratory (LLNL) is embarking upon a new initiative to develop flexible, additive, free-form microfabrication processes capable of achieving arbitrary three-dimensional mesoscale structures with microscale material architectures and sub-micron precision.
What’s the potential impact?
These processes will help revolutionize manufacturing and have a broad impact across many applications. Unique capabilities will include compatibility with a wide range of materials (metals, ceramics and polymers), rapid translation from computer model to fabricated component and scalability to large numbers of components or bulk material billets. Specific objectives include:
1. The use of metals, ceramics and polymers in multiple new fabrication technologies.
2. The ability to fabricate arbitrary three-dimensional mesoscale components with microscale features and precision.
3. The design and fabrication of ”new” materials with specified properties (structural or functional) outside the bounds of those attainable with bulk materials processed via traditional synthesis methods.
4. The investigation and understanding of the physics associated with new process technologies.
We plan to achieve these goals via three new fabrication technologies which require significant development. We have an open post-doctoral research position associated with each of the technologies described below.
* Projection Microstereolithography is a low cost, high throughput, microscale, stereolithography technique which uses a spatial light modulator as a dynamically reconfigurable digital photomask. Projection Microstereolithography is capable of fabricating complex three-dimensional microstructures in a bottom-up, layer-by-layer fashion. The successful post-doctoral candidate will have some background in 3D fabrication, microsystems, polymer physics or chemistry, nanoparticle suspensions, material characterization, instrument development, instrument troubleshooting and linear optical systems. A multi-disciplinary, experimental background is preferred.
* Electrophoretic Deposition (EPD) is a bottom-up fabrication process that utilizes electric fields to deposit charged nanoparticles from a solution onto a substrate. EPD can be used with a wide range of nanoparticles including oxides, metals, polymers and semiconductors. The successful post-doctoral candidate will have some background in electrokinetics and/or electrochemistry, nanoparticle suspensions and material characterization. Background in linear optical systems is preferred but not required.
* Direct Ink Writing (DIW) is a printing approach in which concentrated, functional inks are deposited in a layer-by-layer fashion to create complex 3D architectures. DIW is a multi-material and multi-scale process that is useful for many emerging applications. The successful post-doctoral candidate will have some background in additive manufacturing techniques, rapid prototyping platform design and assembly, nanoparticle synthesis and processing and materials characterization. A skilled experimentalist with demonstrated modeling proficiency is preferred.
