  • Patent number: 10309985
    Abstract: Methods for creating build sequences which are determined using computational chemistry algorithms to simulate mechanosynthetic reactions, and which may use the mechanosynthesis process conditions or equipment limitations in these simulations, and which facilitate determining a set of mechanosynthetic reactions that will build an atomically-precise workpiece with a desired degree of reliability. Included are methods for error correction of pathological reactions or avoidance of pathological reactions. Libraries of reactions may be used to reduce simulation requirements.

  • Patent number: 10138172
    Abstract: 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.

    Inventors: Robert A. Freitas, Jr., Ralph C. Merkle
  • Patent number: 10072031
    Abstract: Systems and methods for mechanosynthesis including those that avoid the need for a bootstrap process, avoid the need to build tips via mechanosynthesis, avoid the need for charging tips with feedstock during a build sequence, avoid the need to dispose of reaction byproducts, reduce the design complexity of new tips, and reduce or avoid the need for multiple positional means or tip switching.
