Apparatus (1) for additive manufacturing, comprising at least one material filament (2), at least one printing head (26a) for the at least one material filament (2) and feeding means, particularly at least one spool (4), for the at least one material filament (2), wherein the apparatus (1) is designed for producing at least a section of a workpiece (7) by fusing the at least one material filament (2) and forming a layer (10) of the fused material of the at least one material filament (2) by depositing the at least one fused material filament (3). According to the invention an optical fibre (5), an additional printing head (26b) for the optical fibre (5) and feeding means, particularly a spool (6), for the optical fibre (5) are provided, wherein the optical fibre (5) is separate from the at least one material filament (2) and from the at least one fused material filament (3), wherein the apparatus (1) is designed for depositing and embedding the optical fibre (5) into the layer (10) of the fused material of the at least one material filament (2), and wherein the additional printing head (26b) can be controlled independently from the at least one printing head (26a).
