Abstract
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.
Claims12
A printing device (10) for a 3D printer, the printing device comprising:
- a metering unit (18) configured for melting and plasticizing a material (38) to be printed;
- a discharge unit (14) configured for printing the material (38) supplied via the metering unit (18), the discharge unit (14) having a nozzle opening (74) through which the discharge unit (14) is configured to dispense the material, and
- a transport system (86) including a motor (M) configured to transport the discharge unit (14) to the metering unit (18) and to a workpiece to be manufactured;
- wherein the metering unit (18) and the discharge unit (14) are arranged separately from each other and are configured to be connected to each other,
- wherein the discharge unit (14) is configured to be transported to the metering unit (18) by the transport system in order to receive the material (38), and
- wherein the nozzle opening (74) of the discharge unit (14) and a coupling point (62) of the metering unit (18) are configured to come into contact with each other in order to connect the discharge unit (14) to the metering unit (18) such that the discharge unit (14) is configured to receive the material from the coupling point (62) via the nozzle opening (74).
