Embodiments of the present invention provide for a material extrusion system for three-dimensional (3D) printing/additive manufacturing. The material extrusion system can include a nozzle head configured to extrude a liquefied material of variable widths through an adjustable orifice, wherein the nozzle head can change sizes during a line to compensate for wider or thinner wall thickness.

The invention relates to a printing device (10) for a 3D printer. The printing device comprises a metering unit (18) for melting and plasticizing a material (38) to be printed and a delivery unit (14) for printing the material (38) provided via the metering unit (18). The metering unit (18) and the delivery unit (14) are arranged separately from each other and can be connected to each other, wherein the delivery unit (14) can be transported to the metering unit (18) in order to receive material (38) and, in order to connect the delivery unit (14) to the metering unit (18), a nozzle (74) of the delivery unit (14) and a coupling point (62) of the metering unit (18) come into contact with each other.

A method of using solid profile rods instead of the usual filament coils for additive manufacturing methods such as 3D printing for industrial applications such as aircraft manufacturing, and to enable a more rapid production of fiber-composite components. The additive manufacturing device, or the 3D printer which generates the component layer by layer, respectively, comprises a material magazine in which a plurality of profile rods are stored. The profile rods are pre-tailored and are adapted to the component layer by layer. The profile rods, when printing, are successively retrieved from the material magazine and, by way of an infeed installation, guided to the nozzle of the additive manufacturing installation and subsequently applied to the printing bed so as to form the component layer by layer.
