| Abstract Scope |
The complexity of the ink-based printing supply chain and the manufacturing time cycle, combined with the expensive ink formulation processes, contaminants, limited printing inks, machine cleaning, and post-processing, have hindered the printed electronics industry for decades. This talk presents ink-free printing technology where the final devices can be printed directly from raw materials in a single step, breaking the barriers for prinitng various functional materials and devices. In this process, pure nanoparticles of various materials, including metals, semiconductors, and insulators, are laser-generated and laser-sintered in situ and on demand. This eliminates ink-associated manufacturing pollution, contamination, cost, and time, as well as the need for post-processing. It further allows the printing of multimaterial and hybrid structures. This technology transitions electronics printing into a new realm, where pure, multimaterial, multifunctional, and hybrid materials are printed on demand for applications spanning the electronics, energy, healthcare, automotive, aerospace, and defense industries. |
