There are proposed a 3D printer optical engine and printing system capable of forming a single light engine by integrating light sources. A light engine installed under a tank accommodating a photocurable resin and configured to provide a light source for the molding of an output product to the tank includes: a light engine case detachably mounted under the tank, and having an accommodation space therein; a backlight module detachably installed in the lower portion of the accommodation space of the light engine case, and configured to provide backlight; and an image switching module detachably installed in the upper portion of the accommodation space of the light engine case while being spaced apart from the backlight module, and configured to cure the photocurable resin by radiating a light source corresponding to a tomographic image of the output product onto the tank.
