Creating objects suddenly by pointing a wand is a common view during any magic show. Magicians make the audience to scream with amazement by creating and disappearing solid objects in the space. But that was past. Now we have that eye tricking magic, converted in to a reality through the application of science. That is 3D printing.
As mentioned already 3D printing is a wonderful process of making 3 dimensional solid objects from a digital file. A creation of a 3D printed object is achieved by laying successive layers of materials until the object is created. This process consists of several sequential steps.
In order to get a 3D printed object, it is necessary to have 3D digital copy of the object. This can be created by using 3D modeling software or 3D scanner(Used for existing objects). Once the 3D model is created, next step is to prepare its 3D printable. The preparation of 3D model is known as slicing. Slicing is dividing a 3D model in to hundreds or thousands of horizontal layers and need to be done with software. When the 3D model is sliced it should be fed to the 3D printer and this can be done via USB, SD or Wifi. When the file is uploaded in a 3D printer, the object will be printed layer by layer. The SD printer reads every slice (2D image) and creates a 3-dimensional object.
Scientists predict in the near future 3D printing will change the manufacturing world with its effects on energy use, waste reduction, customization, product availability, medicine and many other uses. I believe that 3D printing is a good example to acknowledge that with the aid of science all magical phenomena can be performed in the real world.
