Rafael Enrique Hidalgo 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).

  • Publication number: 20220324173
    Abstract: There is provided improved laser sintering systems that increase the powder density and reduce anomalies of the powder layers that are sintered, that measure the laser power within the build chamber for automatic calibration during a build process, that deposit powder into the build chamber through a chute to minimize dusting, and that scrubs the air and cools the radiant heaters with recirculated scrubbed air. The improvements enable the laser sintering systems to make parts that are of higher and more consistent quality, precision, and strength, while enabling the user of the laser sintering systems to reuse greater proportions of previously used but unsintered powder.
    Type: Application
