In this paper, the use of infrared sensor installed in the model sensor device is presented. Infrared sensor measured distance of the model surface and the data are used to reconstruct the 3D image. The implementation of five sensors helps in reducing time for data collection, and blind spots can be minimized. The scanning device consists of IR sensor array is placed in a black box with the object in the middle. The scanning process required the object to turn 360° in clockwise in x-y plane, and the resolution for z-axis is 2 mm in order to obtain data for the image reconstruction. Four different lower limb prosthetic models with different shapes were used as the object in the scanning experiments. The device scan object diameter every 2 mm in thickness, 100 mm in height, and total time require to collect data for each layer is 60 seconds. The reconstructed object accuracy is above 90 % based on the comparison between a solid and printed model dimension. The accuracy for each model, and all results and graphs are shown in the paper.
