D printing lithophanes is where you turn 2D images into 3D models, which, when you 3D print and backlit, it reveals the image ...

See, a slicer is a piece of software for your PC or Mac that can convert a 3D model file -- normally with the file extension .STL, .3MF or .OBJ -- into a file that is usable by your 3D printer.

Before printing anything, you need a 3D model of the object you’re trying to create. The computer model is then "sliced," essentially dividing it into hundreds (or potentially thousands) of layers.

Its robotic arm draws instantly solid 3D curves rather than 2D slices, shedding the need for direct support or even a horizontal surface. It's also not bound by traditional approaches to color.
