NIST only participates in the February and August reviews.
Additive manufacturing (AM) is a rapidly growing technology, but its commercial adaptation to ceramic-based materials lags behind the metals and polymers sectors. Innovations that improve the availability of reliable, custom, on-demand ceramic parts will benefit a range of structural, thermal management, medical, and electronic applications. These applications often call for multi-material or composite parts that require ceramics to be integrated with less-refractory materials [1]. The ceramic AM field will progress with innovations that combine experience from traditional ceramic processing with recent breakthroughs in densification of ceramics, like cold sintering[2] or ultra-fast high-temperature sintering [3].
Our effort at NIST focuses on developing predictive tools for ceramic AM by combining computational and experimental approaches to study fundamental material processes during direct-ink writing and post-processing of ceramic parts. We are interested in postdoc candidates with prior experience in any of the following areas: ceramic processing, nano-particle synthesis, colloidal chemistry (i.e., rheological testing, zeta-potential), advanced characterization (ultrasound, x-ray scattering, IR imaging), and experimental equipment design (CAD, controls (i.e., LabView, Python, Arduino, G-code), image/video processing (i.e., ImageJ).
