DiscussionDiscussion
The study investigated on the mechanicalThe study investigated on the mechanical
properties ofproperties of Ti-6Al-4V from AM process.
The properties testedThe properties tested included:
 failures,
fracture toughness,
 impact resistance hardness
 finally test for fatigue.
 Above properties are affected by dynamism
of heat effect

ConclusionConclusion
properties of Ti-6Al-4V have been
enhanced by the process AM
The product has high strength to weigh
ratio
Also increased resistance to corrosion
Perfect for use in aerospace and
biometric
