3d printers can "print" real 3D objects, such as print a robot, print toy cars, print a variety of models, and even food.
3d printers are often used in the field of mold making, industrial design and other areas are used to manufacture models, and gradually used in the direct manufacture of some products, there has been the use of this technology to print and become the parts.
3d printer technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems (GIS), civil engineering, firearms, and other fields.
In the United Kingdom, technicians scan the feet and ankles of Olympic sprinters, feed the data into a computer, and after a few simple steps of computer calculations, the technicians are able to 3D print new shoes exclusive to each athlete, which conform to the athlete's size, weight, gait, and preferences.
On the other side of the globe, NASA tested a Mars spacecraft in the Arizona desert with customized, 3D-printed metal parts on its deck. Most of these parts have complex shapes, with many curves and cutouts, and can't be produced by anything other than a 3-D printer.
In Japan, a mother-to-be wanted to commemorate her first ultrasound test by having her doctor edit her ultrasound images and 3D print a lifelike model of her fetus. The result was an avant-garde 3D-printed plastic model of a tiny fetus in a clear block of hard plastic.

3D Printer Principle Technology: Ordinary printers used in daily life can print computer-designed flat items, and the so-called 3D printers and ordinary printers work on basically the same principle, only the printing material is a little different, ordinary printers are printed with ink and paper.
While the 3D printer is equipped with metal, ceramics, plastic, sand and other different "print materials", is the actual raw materials, the printer is connected to the computer, through the computer control can be "print materials" layer by layer stacked up, and eventually The blueprints on the computer into a physical object.
3D printing commonly used materials are nylon fiberglass, durable nylon materials, gypsum materials, aluminum materials, titanium alloys, stainless steel, silver-plated, gold-plated, rubber materials.
