About 3D Rapid Prototyping Machines

3D printing is a rapid process that layered build a prototype or model. The process adds layers of new material in liquid or powder form and fixes it in the desired contour. The process is controlled by a computer program, and takes place in special prototype machines that also called 3D printers.
Essential to produce a prototype of a 3D printer is a 3D data file of the part to be made.
The advantage of 3D printing is that according to a 3D data file to create a physical part quickly and cost-effective, and without the use of casting tools.
3D printing available today for example in product and industrial design, architecture and other model building, and in orthopedics and technical aids.

One of these are the MakerBot

3D printing can be an important contribution in development of new products by making a prototype that can be tested both functionally and design wise.
