How to print prototype using 3D printer? The technology in 3D printer is as same as 2D printer. Only in the material are they different.  Ink and paper is the basic material for 2D printer. Plastic is the major component for 3D printer. The other side of  towhead connects with plastic line. When  towhead moves along horizontal line,  the vertical side  is controlled by the movement of print bed, which is made up of glasses and rubber.

3D printer dissect 3D model into miniature. The raw material for printing prototype comes from a plastic rod, melted by heating head. The material choosing is very tough. This kind of material should meet the requirement that it can easily be melted a little above 100 centidegree temperature. In addition it could be cooling in room temperature. So the heating process is carefully controlled by a electrical heat sensor connected to a temperature controller. The rod is extruded using high compressed air from the large tank.

The rod and towhead are propelled by motor, also made by 3D printer. At the start point 3D printer decodes CAD model,  designed by special software. The printer sends signal to drive the motor moving according to the plan. When one layer is completed, the printer bed lower height for ready anthoer layer.  All of work is planned by computer program automatically.

3D printer creates a model over a period of hours  by turning a 3D CAD drawings into lots of two-dimensional, cross- sectional layer. Instead of using ink and paper,  which never build up to much volume, the 3D printer deposits layers of molten plasic or powder and fuses them together with adhesive and ultraviolet light.
