Abstract: The present disclosure relates to a method of controlling a 3D printer for construction which prints and forms various structures, in which a controller 10 configured to control the 3D printer for construction, a scanner 30 configured to detect stereographic surface information, and a computer 40 connected to the controller 10 and the scanner 30 are provided so that the scanner 30 detects actually measured surface information 39 of a printing matter 20 and transmits the detected actually measured surface information 39 to the computer 40, and the computer 40 compares the actually measured surface information 39 with planned surface information 49 to calculate a printing error and then corrects command information 19 such that the printing error is compensated for and transmits the corrected command information 19 to the controller 10.
