Patents by Inventor Steven Frederick Wright

Steven Frederick Wright 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).

  • Build materials for additive manufacturing applications
    Patent number: 11780956
    Abstract: A build material for additive manufacturing applications is disclosed. The build material includes a build composition in powder form. The build composition includes a semi-crystalline polymer having a glass transition temperature of at least 60° C. as measured by DSC and a minimum crystallization half-time of greater than 100 minutes as measured by SALS. A semi-crystalline polymer useful in additive manufacturing applications, an additive manufacturing method for producing a three-dimensional object and an additive-manufactured polymer article are also described.
    Type: Grant

  • COMPOSITIONS FOR THE PRODUCTION OF OBJECTS USING ADDITIVE MANUFACTURING
    Publication number: 20170145155
    Abstract: Objects can be produced using an additive manufacturing process. The objects can include a plurality of layers of a polymeric material that includes a copolyester ether. The copolyester ether can include units of a diacid component and units of a glycol component. In some implementations, the units of the diacid component can be derived from at least one aliphatic dicarboxylic acid. Further, in some illustrative examples, the units of the glycol component can be derived from an aliphatic glycol and a polyalkylene ether glycol. In some cases, the polymeric material can also include a thermoplastic elastomer and a resin component.
