Abstract
A 3D printing system comprises a 3D printing arrangement operable to print a 3D object, a processing unit operable to analyse images captured by an infra-red camera to detect the state of the object being printed, a substrate upon which the 3D printed object is adhered during the 3D printing process; and an infra-red light source arranged to illuminate the substrate in such a manner so as to cause total internal reflection of the infra-red light to occur in the substrate when the 3D object is not adhered to the substrate, wherein the infra-red camera is arranged to view the surface of the substrate opposite to that which the 3D object is printed upon so that the camera may capture images of the 3D object when it is correctly adhered to the substrate; and the processing unit is operable to analyses the captured images to detect whether the 3D object is correctly adhered to the substrate.
