3d printing robot, 3d printing robot system, and method for producing an object using at least one such 3d printing robot

A mobile 3D printing robot system comprising:

• at least two mobile 3D printing robots, wherein each of the at least two mobile 3D printing robots comprise:
• a robot arm;
• a stand unit for the temporary setup of the robot arm on an underlying surface;
• at least one 3D printing device having at least one printhead which is movable by the robot arm and is provided for dispensing at least one printing material;
• an electronic control unit, which is provided at least for actuating the 3D printing device;
• and
• a receiving unit of a global navigation satellite system which is connectable at a predetermined fixed distance in relation to the printhead;
• and
• at least one electronic main control unit which has a data connection to the electronic control units of the at least two mobile 3D printing robots and is provided for the purpose of specifying predetermined parameters for the joint production of an object to the electronic control units of the at least two mobile 3D printing robots.

A method for producing an object using at least one mobile 3D printing robot, the method comprising:

• reading out predefined parameters, executed by an electronic control unit, for producing the object, wherein the predefined parameters include at least a plurality of target positions of a receiving unit of at least one mobile 3D printing robot, wherein each of the at least one mobile 3D printing robots comprise:
• a robot arm;
• a stand unit for the temporary setup of the robot arm on an underlying surface;
• at least one 3D printing device having at least one printhead which is movable by the robot arm and is provided for dispensing at least one printing material;
• an electronic control unit, which is provided at least for actuating the 3D printing device;
• and
• a receiving unit of a global navigation satellite system which is connectable at a predetermined fixed distance in relation to the printhead;
• ascertaining an actual position of a printhead from the data of the receiving unit;
• based on the ascertained actual position, assuming a first target position of the receiving unit within a predetermined tolerance interval;
• dispensing at least one printing material at all target positions of the printing material which are provided at the first target position of the receiving unit;
• assuming a second target position of the receiving unit within a predetermined tolerance interval;
• dispensing the at least one printing material at all target positions of the printing material which are provided at the second target position of the receiving unit;
• and
• repeating the steps of assuming a next target position of the receiving unit and dispensing the at least one printing material at all target positions of the printing material which are provided at the next target position of the receiving unit, until the at least one printing material is dispensed at all predetermined target positions of the printing material.
