James K Santosa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Solid freeform fabrication of structurally engineered multifunctional devices
    Patent number: 7509240
    Abstract: A selective laser sintering technique and system are provided for producing a heterogeneous product. The selective laser sintering technique and system is generally comprised of generating a computer model of the product and processing the model to obtain numerous cross-sectional representations of the model. The cross-sectional representations are manufactured layer by layer to create the product. Specifically, numerous different powders having a variety of properties are placed within nozzles positioned above a deposition bed using a hopper. Using the computer model as a guide, the different powders are placed at different positions on the deposition bed to form each layer of the device. The deposited powders are consolidated, micromachined, and milled using one or more lasers to create the product.
