Abstract— The main
aim of paper is to analyse and design the low cost 3D printer which will print the three dimensional objects. The machine
produces different products with different material. A 3D printer can make
anything from ceramic cups to plastic objects, metal machine parts, stone
vases, and even human body parts. 3D printing is a type of additive
manufacturing process where a three dimensional object is made by layering down
successive layers of material to form the final object. Additive process
or  subractive process is used for 3D
printing. 3D printing is therefore different from traditional machining
techniques which mostly rely on extraction of materials such as cutting or
drilling. The ability to print parts or components which are made from distinct
materials from various mechanical and physical properties in a single build
process is offered. This is the most basic function of it, but there are many
technical glitches in the designing of the current generation low cost printer.
The printed object can be fragile, delaminated due to low quality resolution of
printing, this paper will highlight and gives methodology/techniques to
overcome issue. It will help in overall increase in capacity of it with
increase in the resolution. The appearance and utility of the final product is
provided by current models which are closely emulated by the advanced 3D
printing technologies.

METHODOLOGY     
3D Printers use a laser or extruder (the material output part of the
printer), that move along an X, Y and Z axis to build an object in three
dimensions, wherein successive layers of material are laid down in different
shapes. These layers can be only a few microns thick at a time. This is an
advantage over traditional method which uses subtractive method where materials
are cut or drilled from mould. The layers of materials in liquid, solid or
material form are fused together using additive process. 3D printers thus use
additive manufacturing or direct digital manufacturing technology to produce
proto type of a product. Computer Aided Designing (CAD) software is used. The
object is then built layer by layer. Using this new technology, a manufacturer can
develop a working prototype in just a few hours compared to traditional
prototyping. Ultimately, this results in saving time and cost. Especially since
the additive manufacturing process also minimizes waste.
There are mainly four distinct types of technologies used in 3D printers:
Material extrusion based 3D printers, Photo     
polymer, Selective Deposition Lamination and Binding 3D printers.     There are several
types of 3D printers. Same basic approach is used even though they may use
different material for “printing” an object i.e. spraying or
otherwise transferring a substance in multiple layers onto a building surface,
beginning with the bottom layer. Before the printing process, first create a 3D
image of the product which is to be printed using a computer-assisted design
(CAD) software program. That object is sliced in hundred and thousands of
pieces until each piece is placed on top of the other for the object to be completed.

     One type, called selective laser
sintering, involves heating and solidifying granular material with a laser in a
specific pattern for each slice before repeating over and over again with new
layers; this technique could be used in creating figurines, for example.
Another uses UV light to cure layers of resin. Others deposit material much
like an automated glue gun. CD-ROM  is
used instead of Stepper motor here, Because due to increase in the torque of
Stepper motor, speed decreases. With the CD-ROM, we will try to overcome that
problem. The CD-ROM will provide the axial motion which will eventually deposit
the material through additive process.•                     
RESULTS
& DISCUSSIONS A  laser is used,
which can be move along X, Y and Z axis to build an object in 3D (three
dimensions), wherein successive layers of material are placed  in different shapes. To use the minimal
component and to make the project best out of waste, we are using CD-ROM  instead of Stepper motor. Because due to
increase in the torque of Stepper motor, speed decreases. With the CD-ROM, we
will try to overcome that problem. The object is then built layer by layer.
Especially since the additive manufacturing process also minimizes waste.

               V.   CONCLUSION3D Printing technology is something
that could transform and remould the world. Advances in 3D printing technology
can significantly commute and amend the way we manufacture products
worldwide.  If the industrial revolution brought
us mass production and the arrival of economies of scale – the digital 3D
printing revolution could bring mass manufacturing back a full circle. •
