  • POLYMERIC PARTICULATE MATERIAL
    Publication number: 20250129256
    Abstract: The invention provides particulate material suitable for use in manufacturing a three-dimensional object, the material comprising a plurality of particles. Each particle has a thermoplastic polymeric core; and a polymeric shell that coats the polymeric core. The polymeric core makes up 75 wt % or more of each particle. The polymeric shell is formed from a co-polymer of a major monomer and a minor monomer, wherein the major monomer comprises a polymerisable group, and the minor monomer comprises (i) a polymerisable group; and (ii) a functional component, and wherein the co-polymer is formed by reaction of the polymerisable group on the major monomer with the polymerisable group on the minor monomer.

  • Additive manufacturing
    Patent number: 11179887
    Abstract: A method (300) of fabricating an object by additive manufacturing comprises providing (310) a layer of polymeric material (100), said polymeric material (100) being in particulate form, and comprising linear polymer chains, selectively depositing (320) a reactive liquid (200) onto the layer of particulate polymeric material (100), said reactive liquid (200) comprising reactive units (210a) which are monomeric units, linear oligomeric units, linear polymeric units, or combinations thereof, wherein said reactive units (210a) have two or fewer reactive groups, and allowing (330) linear polymeric chains in said layer of polymeric material (100) to react with reactive units in said reactive liquid (200) so as to form extended polymeric chains that are linear, so as to provide a shaped layer of linear polymer. These steps (310, 320, 330) are repeated as required to form the object from successive shaped layers of linear polymer.
