What is 3D printing Technology?

3D printing technology is an additive manufacturing technology that creates a physical three dimensional objects from a digital design. Additive manufacturing used to build up a component in layers by depositing materials.

you may wonder in coming years by seeing this technology in your PC,Laptop and even in your smart phone. It is very simple as by taking a picture in our mobile and a take a printout. Microsoft and Google already enabled their hardware to perform 3D scanning and printing.

step by step process of 3D printing

General functional principle

1. Modeling

3D printable models may be created with a Computer Aided Design(CAD) package, via a 3D scanner or by a plain digital camera and photogrammetry software. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it. 3D scanners use different technologies to generate a 3D model. Examples are: time-of-flight, structured / modulated light scanning and many more. There are different kind of modelling software also available in the market.

2.printing

The main process here is slicing ,the design file from the computer is sliced into hundreds or thousands of thin layers, which is then sent to the 3D printer. When the 3D model is sliced, you are ready to feed it to your 3D printer. This can be done via USB, SD or wifi. When a file is uploaded in a 3D printer, the object is ready to be 3D printed layer by layer. The 3D printer reads every slice (2D image) and creates a three dimensional object.

3. finishing

Though the printer-produced resolution is sufficient for many applications, printing a slightly over sized version of the desired object in standard resolution and then removing material with a higher-resolution subtractive process can achieve greater precision.

3D printer sales have been growing ever since, and as additive manufacturing patents continue to expire, more innovations can be expected in the years to come. There are now roughly 300,000 consumer 3D printers in the world – and this figure is doubling every year.
