PROCESS CONTROL METHOD FOR A 3D PRINTING PROCESS
This abstract first appeared for US patent application 20250067600 titled 'PROCESS CONTROL METHOD FOR A 3D PRINTING PROCESS
Original Abstract Submitted
a process control method for a 3d-printing process using a 3d printer. the 3d printer has a build platform, a light source, a receiving device for printing material and a control device by which an object can be produced layer-wise or continuously from the printing material. the method includes using a thermal imaging camera, the output signal of which is transmitted to the control device, connected to the 3d printer, the method includes the following steps of illuminating a layer or parts of said layer positionally selectively, detecting the temperature of the layer during the polymerisation using the thermal imaging camera, ending the building process of a layer by ending the illumination, the time of the end of the illumination being established by a predefined temperature tor a predefined change in temperature dt/dt being reached.
