The present study was undertaken to investigate the mechanical properties, surface toughness, accuracy of dimension and corrosion resistance of Ti–6Al–4V alloy prepared by additive manufacturing method using electron beam as the energy sauce. A product having good internal quality, surface quality is provided by choosing current conditions of the electron beam appropriately. The mechanical properties are a rolling product level without heat treatment. If there are even metal powder and 3D data by using the additive manufacturing method, this method can produce complicated products and the superior characteristics like statement above without a mold. However, the manufacturing cost is higher by from 10 times to 100 times than the conventional manufacturing processes. Therefore, the mechanical property, physical property, shape and product cost has to be taken into consideration for a product enough when we choose this additive manufacturing method.
