3d printing vs lenticular printing

3d printing and lenticular printing are two terms used mistakenly by the laymen and even professionals for the visual effect of three dimension presented on a flat surface.  But technically they are not the same thing. In a more subtle way, 3d printing refers to additive manufacturing to create a physical prototype from a digital blue print such as AutoCAD file.  3d lenticular printing, on the other hand, is a way to create 3d illusion by utilizing the concept of selective light redirection to create a fake binocular disparity so as to fool the human minds that something is three dimensional.
