How
3D printers print food?
Most 3D food printers
use FDM (fused deposition modeling) technology, which involves extruding a
viscous material through a nozzle to create a design. The material can be
anything from chocolate to pureed fruits and vegetables to dough. The printer
moves in the X, Y, and Z axes, depositing the material layer by layer to create
a 3D object.
