  • THREE-DIMENSIONAL PRINTING OF HYDROPHOBIC MATERIALS IN FUMED SILICA SUSPENSION
    Publication number: 20230226772
    Abstract: A three-dimensional (3D) printing methodology is disclosed for freeform fabrication of hydrophobic structures without the use of printed support structures. The build material is directly printed in and supported by a fumed silica-containing yield-stress support bath to form an intermediate article in the support bath material. The intermediate article may be liquid or only partially solidified after being printed into the support bath material. The intermediate article is then heated or irradiated with ultraviolet radiation to initiate cross-linking to solidify the printed intermediate article, forming a finished article.
    Type: Application
