Working: All the 3D printers’ posses five basic process functions for creating a three-dimensional model.

First - The Print Surface is fed with a unique powder.

Second - The powder is spread on print surface by a roller at a preset depth. This process takes just a few seconds for its completion.

Third - Color is applied to the powder’s initial layer by the Standard Inkjet Print Heads.

Fourth - The solidification of powdered layer takes place.

Fifth - The lowering of print surface for powder’s another layer is enabled.

This process goes on repeating till the completion of the whole 3D model occurs. The mixture of Ink Jet Color and powder results in formation of a bond. The solidification occurs this way. So, if no printing is carried out at the specified layer or location, the powder retains its state, i.e. it does not get solidified. Once the printing process comes to a halt, the powder gets blown out, thereby leaving the output which is the reflection of the original model or drawing. Depending on complexity and size of output, this process takes around ½ an hour. These 3D printers do a commendable job, especially when pre-production examples or working prototypes of the specified objects are seen on the computer monitor.
