Abstract

The invention relates to a filament connector for connecting respective ends (1, 2) of filaments (3, 4) for the additive manufacturing of a three-dimensional object in fused filament fabrication, the filament connector comprising: —at least two mold elements (5, 6) which can be put together; and—a filament negative mold (8) in which the ends (1, 2) of the filaments (3, 4), which ends have previously been melted in a melting region (24) of the filament connector, can be joined together by the solidification of the melt of the filament materials of the two ends (1, 2). The filament negative mold (8) forms the melting region of the filament connector; within the filament negative mold, the ends (1, 2) of the filaments (3, 4) can be melted by an input of heat and can be joined together by the solidification of the melt of the filament materials of the two ends (1, 2).
