Claim 0:
1. An additive manufacturing process for the manufacture of an object in an additive manufacturing apparatus, wherein the object is formed by one or several individual solid filamentous units, said additive manufacturing process comprising the steps of,
discharging a polymer composition in a molten state from a nozzle of a print head, thereby imparting an orienting flow on said polymer composition in a molten state being discharged from said nozzle of the print head and depositing the discharged polymer composition in a molten state along at least one predefined path and allowing the thus formed one or several filamentous units to solidify such as to form one or several solid filamentous units of the object to be manufactured;
optionally repeating the previous step until the object is formed;
wherein said polymer composition consists of a thermotropic liquid crystal polymer as the polymer component of the polymer composition or consists of a thermotropic liquid crystal polymer as the polymer component of the polymer composition and non-polymer additives or reinforcing fibres,
characterized in that the smallest thickness of the one or several filamentous units is equal or less than 0.2 mm.
