Methods, systems and workpieces using mechanosynthesis
Methods and systems for building three-dimensional workpieces are described using a plurality of mechanosynthetic reactions. These methods may employ engineered reliability in reactions and process conditions and may use simulated or otherwise vetted reaction sequences, to allow workpieces requiring many reactions to be built with acceptable reliability. These many reactions may be the repetition of one or a small number of reactions, or many diverse reactions, or a combination thereof.
