Additive Manufacturing

Abstract
Manufacturing process is the root of the
industry. It is divided by the main four group,
Forming, Fabrication (joining), Machining
(subtracting) manufacturing and casting
(Additive manufacturing).
In modern technology, industry tries to use
and engage with the additive manufacturing.
There are lots of developments in this industry
revolution. Additive manufacturing processes
fill the desired shape and size as per the
requirement. Then deposit the layer by layer
on the top of the layer.
This is the best example of the rapid
manufacturing in industry. Industry need cost
effective and reduced the time and effort with
good quality. Additive manufacturing is very
advance technique and it is very important for
quality consideration. In this report will
provide the application of additive
manufacturing and impact on the industry.
Additive manufacturing also called as 3d
printing, used for the rapid prototype. Additive
manufacturing use the metal powder and very
vast use in the field of Automotive. More
descriptions are given below in details.

Introduction
In manufacturing, there are many
manufacturing process exist for making single
product. We cannot define the all process
here. Manufacturing is vast process, where
the product comes from the raw material. All
manufacturing process have its own skill and
uses to produce the product, it is not easy to
say here and cont the manufacturing process.
The most and running process in industry are
Additive process for the fast and quality
prototype. Here are the main group of
manufacturing main four groups, Forming,
Fabrication (joining), machining (subtracting)
manufacturing and casting (Additive
manufacturing).
Forming process, it is a manufacturing
process. Products are manufactured with the
help of the Die and hydraulic press. In which
the raw material convert the desired shape by
pressing between die. The grain orientation
doesn’t effective.
Fabrication: in this process joining the similar
or dissimilar part with the help of the welding
fastener and assemble them. It is also called
joining process.
Machining process: it is a process where the
raw material converts to desired part by
removing the part from the raw material.
These processes are done with the help of the
cutting tool. It is also called subtracting
manufacturing.
Casting (additive process): Casting process is
the very traditional method and started by
melting the raw material and filled in the mold
or desired sculpture (replica of the part). It is
called additive manufacturing. In this
technology there are changes in the process.
Additive manufacturing or raid prototype is
the new technology in which we get the
product by deposit the layer on the layer in z
direction. It is a quick process to get the
prototype. This is called digital manufacturing.
Here in this report we will focus on the
additive manufacturing process. There are
several stages to produce part with the help of
the additive manufacturing. It describe below
in more detail.
Literature review
Additive technology is the next step of the
casting process that has traditional
manufacturing process. Additive
manufacturing started in 1980. It is growing
rapidly and started into the aerospace as well.
Here is some data for the development of the
additive manufacturing.
Current status of metal Additive
manufacturing are given below in table.
Additive manufacturing is the process, in
which material added layer by layer. This is
mostly done layer by layer. There are steps
below for the common understanding of the
additive manufacturing process.
1. Design the model for the part in CAD
software.
2. Convert the format to STL format
