Electrically conductive surfaces for 3D printed structures

This thesis describes the technical possibilities of coating various 3D printed structures by different coating methods. Different surface structures have been created on two models for two 3D printing technologies. Antennas on FR4 and PLA substrates were simulated. After adjusting the dimensions of the antennas in the simulations and the results obtained from the simulations, two speckle antennas on PLA substrate were created. To form the antennas, the substrate was coated with copper foil and electrically conductive spray. Subsequently, the antennas were measured, and the results were compared with the simulations
