The intention of this paper is to perform a preliminary investigation in order to ascertain if lock-in thermography can be used for non-destructive inspection of samples manufactured with 3D printing. This because of the ever more increasing interest that 3D printing and additive manufacturing are gaining from both the industrial and academic communities. To this end, some samples have been produced by means of the fuse deposition modeling technique and with inclusion of some artificial defects at a certain depth through the thickness. Such samples are inspected with lock-in thermography and the obtained results seem promising.
