### Instruction: What is the difference between laser cutting and 3D printing?
### Response: 3D printing is an additive technique while laser cutting is subtractive. In a 3D printer, the material gets heated up and extruded through a nozzle, forming three-dimensional objects. In contrast, a laser cutter cuts two-dimensional plates. For this, a laser burns away parts of the material. Thus, laser cutting can only produce two-dimensional shapes. However, it is much faster than 3D printing.
