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