  • Publication number: 20240124676
    Abstract: A improved method of additive manufacturing of a recycled granulate is provided. The method comprises providing a starting article. A shredder shreds the starting article to give a shredded product. A granulator shreds the shredded product to give a recycled granulate. The recycled granulate is fed into an additive manufacturing machine. The additive manufacturing machine prints a printed article using the recycled granulate. The method does not comprise a step of compounding the recycled granulate using a twin screw extruder. The starting article, the shredded product, and the recycle granulate each comprise a fiber reinforced polymer composite.

  • Patent number: 11554364
    Abstract: A method of forming a catalyst is provided herein. The method comprises combining a binder, a support, and an active metal to form a slurry composition. The method further comprises applying the slurry composition using an additive manufacturing process to form a green part. The method further comprises exposing the green part to heat at a temperature of from about 10° C. to about 150° C. to form the hardened part. The method further comprises applying a ceramic-based coating material to the hardened part to form the catalyst.

  • Patent number: 10875960
    Abstract: A silane-modified polyester blend comprising a polyester polymer homogeneously blended with silane molecules containing two or three alkoxy groups bound to the silicon atom, wherein said silane molecules are present in said polyester blend in an amount of 0.05-20 wt % (or, e.g., 0.05-10 wt %, 0.05-5 wt %, or 0.05-2 wt %). The polyester polymer may, in particular embodiments, be a polyhydroxyalkanoate, terephthalate-based polyester, adipate-based, or succinate-based polyester. The silane molecule may be according to the formula (R2O)2SiR3R4, wherein R2 groups are independently selected from alkyl groups containing 1-4 carbon atoms; and R3 and R4 are independently selected from OR2 groups and alkyl groups containing 1-12 carbon atoms, provided that at least one of R3 and R4 is an alkyl group, wherein the alkyl group optionally includes one or more heteroatoms selected from oxygen, nitrogen, halogen, sulfur, phosphorus, and silicon. Methods for producing the silane-modified polyester blend are also described.
