Summary
Selective Laser Melting of Aluminium Alloys Nesma T. Introduction to selective laser melting Many industrial sectors are benefiting from the possibility of fabricating intricate structures using additive manufacturing (AM) technologies to achieve the objectives of light-weighting, increased functionality and part number reduction. They have the potential to fulfil demands for reducing the cost and design-to-manufacture time through savings on raw materials and replacement of a series of production processes by a single step process [1, 2], reducing lead times in multi-process fabrication [3,4,5,6,7]. A focus is the correlation between the process and the resultant microstructure, mainly governed by the mode of melting and solidification behaviour, as well as the local and bulk mechanical behaviour of the material
