Temperature distribution in Additive Manufacturing involving Titanium Alloy (TI-6AL-4V)

Abstract
Numerous advantages and profits have been realized by the industrial sectors that use the
technology of additive manufacturing. These benefits are not comparable to the conventional
methods which include the use of subtractive manufacturing that is characterized by a little
volume of product prototyping. Majority of the industries that utilize this kind of technology
include aerospace and biometrics where the processes of manufacturing must be supported
effectively and accurately. As a result of the continuous use of this particular alloy of titanium
(Ti-6Al-4V), the research to advance on its application has been considered a very interesting
area of study. It has never been easy to have this kind of precious alloy formed by the other
conventional means.
Such institutions, as well as industrial set up that use Ti-6Al-4V, are very sensitive and
therefore very high levels of accuracy are required. This is the reason why a lot of studies have
been focused on the establishment of the fine properties of Ti-6Al-4V in order to ensure that its
mechanical values are enhanced as much as possible. This particular paper piece has
concentrated on the application of additive manufacturing on Ti-6Al-4V through use of
experiment while seeking to evaluate heat distribution.

INTRODUCTION
Most of the industries in clouding the aerospace, biomedical among others have taken a
keen interest in the use of additive manufacturing in the production of the tailored products.
Additive manufacturing that is commonly known as AM is one of the means of generating
complex- shaped components of metals which are appealing and conforms to the specific
applications. A metallic feedstock that may be in the form of a wire can be possibly be processed
to produce a greater volume by just an application of model data, computer numerical
control(CNC), directed energy and inert atmosphere[2].
The research of the project is set to begin with the definition of various experiments.
Every experiment will be defined with the utility to the overall objectives properly utilized. The
important ant measurements of the experimental in situ distortion together with the temperature
measurements that are carried out during Laser Powder Bed Fusion Additive Manufacturing
process will be considered key. The research employs an implementation of novel measurements
and techniques which allows for the in situ distortion. This will also allow for the measurement
of the temperature during the process of building[1].
The design of the measurement equipment has been done in a manner which allows for
taking of measurements while the powder bed system operations in a configuration of default
nature. The in situ measurement will be completed while comparing temperature for the
experimental build up and distortion. This will allow for the comparison of the use of the scan

and rotating pattern. The measurements that will be made as part of the study will eventually
demonstrate the increased distortion that will be a consequent of the application of the constant
scan pattern[1]. It is expected that the in situ measurement obtained to reflect what had been
previously measuring used in the distortion evolution in the entire process. The non-constant
distortion accumulation through the process of building will assist in the identification of the
problem with the present modeling techniques of LPBF.
The next stage will include the analysis of the in situ measurements of the temperature
for the Laser Powder Bed Fusion Manufacturing process and its distortion effects. It is to be
characterized by the measurements of at least five cases of experiments using the previously
constructed systems of measurements for the advanced analysis within the process of LPBF. The
research will involve making the comparison that utilizes the in situ measurements of the
temperature of distortion in the process of building[4]. The comparison is to be made while using
in situ measurements for Inconel ® 718 and Ti-6Al-4V with two varying geometries.
It will be very interesting to have a comparison between the experimental constructions
that have been produced through the machine component, EOS M280 machine, and the Reni
Shaw AM250. The in situ results of temperature and distortion components are built the common
machines of LPBF which assist in the identification of the weaknesses and strength of every
machine. The complexity of the implementation of mitigation techniques within distortion and
evolution will be properly illustrated with the result. The study will, therefore, focus on making
measurements which can validate future models of FE thereby providing a comparison for
variable build material and machine of the powder bed. In the evaluation of the experimental
validation of Finite Element Modeling for the Laser Powder Bed Fusion Deformation, there will
be the utilization of two experimental models[6]. One of the experiments utilizes a constant scan
