Which type of printer creates three-dimensional objects?

A 3D printer is designed specifically to create three-dimensional objects by adding material layer by layer based on a digital model. This technology utilizes different methods, such as Fused Deposition Modeling (FDM) or Selective Laser Sintering (SLS), to build objects from materials like plastic, metal, or resin.

In contrast, impact printers, inkjet printers, and laser printers are all types of two-dimensional printers that produce images or text on flat surfaces, such as paper. Impact printers work by striking an inked ribbon against paper, creating text and images through direct contact. Inkjet printers spray tiny droplets of ink onto the paper to form images and text, while laser printers use a laser beam to create an electrostatic image on a drum, which is then transferred to paper with toner.

Therefore, the unique capability of a 3D printer to produce tangible three-dimensional products clearly sets it apart from the other types of printers listed.
