According to GlobalData’s company profile on Jabil, Powder bed fusion was a key innovation area identified from patents. Jabil's grant share as of September 2023 was 50%. Grant share is based on the ratio of number of grants to total number of patents.

A recently granted patent (Publication Number: US11773283B2) discloses a composition that includes a blend of two specific polymers. The composition consists of an elastomer toughened styrenic polymer with discreet domains of polymerized conjugate diene dispersed within a styrenic matrix, and a vinyl aromatic-maleic anhydride copolymer. The elastomer toughened styrenic polymer makes up 25% to 50% of the composition by weight, while the vinyl aromatic-maleic anhydride copolymer comprises 20% to 45% of the composition by weight.

The elastomer toughened styrenic polymer mentioned in the patent is a copolymer of styrene and a conjugated diene, and optionally an unsaturated nitrile. In one specific embodiment, the copolymer is made of styrene and butadiene. The conjugated diene is present in the elastomer toughened styrenic polymer in an amount of about 5% to 15% by weight.

The vinyl aromatic-maleic anhydride copolymer can be a styrene-maleic anhydride copolymer, a vinyl aromatic block elastomer with maleic anhydride grafted onto it, or a combination of both. Examples of vinyl aromatic block elastomers include styrene-(butadiene)-styrene (SBS), styrene-isoprene-styrene (SIS), styrene isoprene butylene styrene (SIBS), styrene-(ethylene-butylene)-styrene (SEBS), or a mixture thereof. In one specific embodiment, the vinyl aromatic block elastomer is SEBS.

The vinyl aromatic-maleic anhydride copolymer contains maleic anhydride in an amount of about 5% to 50% by weight of the copolymer. Additionally, the composition may also include a copolymer of an acrylate and a vinyl aromatic monomer. This acrylate-vinyl aromatic copolymer can further contain a conjugated diene, unsaturated nitrile, or a combination of both. An example of this copolymer is methyl methacrylate-acrylonitrile-butadiene-styrene (MABS).

The composition described in the patent can be used to produce filaments with a diameter ranging from about 1 millimeter to about 3 millimeters.

In summary, the granted patent discloses a composition consisting of a blend of an elastomer toughened styrenic polymer and a vinyl aromatic-maleic anhydride copolymer. The composition can be used to produce filaments of a specific diameter.
