Abstract
​
In this study, Inconel 718 alloy has been produced in the EOSINT M270 Laser Melting Machine. This work thus aimed to develop scan speed and step over parameters. These parameters are very important for the quality and properties of the resulting product. To achieve a quality result reference from the accepted parameters was taken; various scan speed and step over distance parameters 12 mm x 12 mm x 5 mm cross sectional INCONEL 718 samples were produced. Samples were used, examined and compared with respect to surface quality, balling, spatter and porosity.
