About 3D printer and its working
3D printer is a printer that is used for the purpose of creating three dimensional objects. This
includes processing materials that are further solidified by controlling the computer (Joshi and Sheikh
2015). This includes liquid molecules or powder grains for creation of the three dimensional objects
in the form of different layers. Charles Hull in the year 1984 developed this technology for the
purpose of printing physical 3D objects from digital data. For this purpose Charles Hull obtained a
patent for working with the technique “Stereo lithography” in the year 1986. In the early 1990s it was
believed that 3D printing are only suitable for producing aesthetical prototypes of functional
prototypes. This are further termed as rapid prototyping (Bandyppadhay, Bose and Das 2015).
However with the growth in technology it is observed that 3D printing has become a part of industrial
production technology and is known as additive manufacturing. The objects created with the use of
3D printing are complex in shape and are with very sharp geometry shapes. This are produced starting
from a digital 3Dmodel or a CAD file. There are different types of 3D printing processing that are
basically grouped into seven categories. This categories includes material jetting, powder bed fusion,
vat photo polymerization, binder jetting, material extrusion, sheet lamination and directed energy
deposition (Mohr and Khan 2015). This are mainly known as rapid prototyping where the objects get
quickly created with the use of a 3D printer after connecting with computer that is containing the
blueprints for this objects. The future of 3D printing includes developing the complex engine parts, in
the fashion industry, in medical application and are also used in space explorations.
Apart from the concept and working of 3D printing, it is observed that there are three general
principles that are needed to be focused while creating objects. The printouts created can be in the
form of any geometry shapes. The objects can be of different shapes and are developed with the use of
electronic data source. This are mainly used as an industrial robot (Guo et al. 2015). The important
principles associated with the 3D printing technology are as follows:

 Modelling: The models that are used as a 3D printable can be realized with the use of
Computer Aided Design software pack. This mainly uses a 3D scanner and uses a
photogrammetry software.
 Printing: it is important to examine the errors before printing the model from STL file. The
files that are stored with STL are being processed with the use of a software known as slicer
(Wang et al. 2016). The slicers are mainly used for converting the model into a set of thin
layers. Once the file is being sliced into different layer then the G code file gets created that
stores all the instructions that are further tailored to a particular type of 3D printer.
 Finishing: printing of oversized model is basically referred to an intended object with
standard resolution. It is observed that higher resolution subtractive process produces greater
models. This process is further known as fishing (Kietzmann, Pitt and Berthon 2015).
There are different objectives followed at the time of processing the objects with the use if 3D
printers. The materials used at the time of printing objects. This are as follows:
There are methods that are used for the purpose of melting or softening the materials in order to
synthesize the layers. Selective laser melting and selective laser sintering methods are used in this
process (Radenkovic, Solouk and Seifalian 2016). There are different processes that are used for
sophisticated technologies such as stereolithography. The working of 3D printing includes:
 1st step: this step includes preparation of the printer before printing the design. The user needs
to design a 3D file that are created with the use of CAD software 3D scanners are used for
creating the images directly from the marketplace. Once the printer is ready to print the files,
the user can proceed to the next step (Hagar, Golonka and Putanowicz 2016).
 2nd step: this step is mainly related to the printing process. The user needs to choose the
material that they wish to print and in which material will be better for performing the
specific functions.
