3D printing was first invented in the 1980s, since that date, it has applied for rapid prototyping (RP). Later it has also begun to develop into a future generation technical manufacturing which has likely to grant to the final production as per the demand of the people.

It has presently possible to 3D printing in a broad range of substances that include metal alloys, thermoplastic composites, ceramics, thermoplastics, pure metals, and various arrangements of food. However, 3D printing technology is still in its infancy (development).

But in the future, with the combination of synthetic biology and nanotechnology, it has the larger possibilities to drastically transform various production, logistic, and design procedures.

This web page furnishes an overview of 3D printing and its technologies, as well as its present and future applications:

Technologies Used:   

3D printing surround a wide range of accompaniment processing technologies.  All of these develops an object in consecutive layers which is generally sized 0.1 mm. The mechanism implemented differ significantly, however, all start with a digital scan model and a computer-aided design (CAD).

And it's later organized using slicing software which splits the object into small cross sections which are printed out at the top of the other. 

Generally, there are following classification of 3D printer:

  1. Void a molten or semi-liquid material
  2. Some printers which set a photo operable resin.
  3. Printers which cover or combine the grain of a powder.
  4. Lastly, printers which staff together small parts of paper, metal or plastic.

Modeling:  3D printable designs may be developed with Computer Added Design (CAD) package, photogrammetry software and by a plain digital camera or via a 3D scanner.

3D printed designs developed by CAD provides fewer errors. As well as corrected before printing, permitting confirmation in the module of the object earlier then it is printed.

The reference modeling procedure of creating geometric figures for 3D computer graphics is alike to plastic arts like sculpting. 3D scanning is a mechanism of gathering digital information on the structure and occurrence of a real object, developing a digital model situated on it.

Printing: Error checking is an essential part before printing 3D design. Most of the CAD system produce STL (error) files on output: A process in which the establishment of STL known as ‘repair’ manage such issues in the actual model. Commonly STLs which have been created by a model acquire using 3D scanning  have more of these mistakes.

Once the above process accomplished, the STL file requires being processed by a software known as slicer which transforms the design into a sequence of small layers and produces a G-code file that has manual tailored to a particular type of 3D printer called FDM printers

Later, G-code file can be printed with 3D printing client software. The printing resolutions denote the layer thickness, generally, the layer thickness is around 100 µm (250 DPI), while some machines able to print layers unto 16 µm (1,600 DPI).

Consumer use:

Several Organizations, as well as some projects, are giving efforts to build affordable 3D printers for office and home use.[75]

One of the longest-running projects is RepRap Project which is running in the desktop category. RepRap aims to finalize an open source 3D printer  (FOSH), whose full functionalities are published under the General Public License (GNU), i.e. capable of duplicating itself by printing many of its own plastic parts to generate more machines.

RepRap have already been ready to print metal parts and circuit. Presently the most popular 3D printer in the entire world is the Purse (i3), i.e. a RepRap 3D Printer.

Due to FOSH targets of RepRap, other projects started to use their design as per inspiration, developing an ecosystem of derivative or similar 3D printers, which are mostly open-source designs.

The accessibility to these open-source modules denotes, that variation of 3D printers are easy to formulate. The convolution and quality of the printer designs. However, finished products vary greatly from project to project.

This rapid enhancement of open source (3D printers) is collecting interest in many areas as it provides the use of public domain designs and hyper-customization to forge open source proper technology. Which can also assist in suitable evolution since technologies are economically and simply and made from capital (resources) available to local communities.

There is a rapid decrement in the price of 3D Printer which is available @ less than $1000 in local the market, whether it was about $20,000 in 2010.

Because of the down on its price, 3D Printers are becoming more affordable financially to use for home/public of personal products. Further, 3D Printers used at home may decrease the negative environmental effect of manufacturing by diminishing distribution impacts and material use.

Presently, some organizations are offering software for 3D printing, for the hardware developed by other companies.
