“…Lifecycle cost, sustainability, supply chain and production costs have been less focused on. General aspects of AM (Bikas et al, 2015;Bogers et al, 2016;Brans, 2013;Cardaropoli et al, 2012a;Ferro et al, 2016;Gao et al, 2015;Go & Hart, 2016;Hedrick et al, 2015;Kianian et al, 2016;Lindemann et al, 2015;Mellor et al, 2014;Muita et al, 2015;Nickels, 2016;Rayna & Striukova, 2016;Scholz et al, 2016;Winkless, 2015;Wits et al, 2016;Wong & Hernandez, 2012); industry (Brettel et al, 2016;Gaub, 2015;Fera & Macchiaroli, 2010;Stock & Seliger, 2016); implications of its use (Bogers et al, 2016;Huang et al;Newman et al, 2015;Rayna & Striukova, 2016); example of its application (Caiazzo et al, 2013;Cardaropoli et al, 2012b;Gupta et al, 2016;Huang et al;Uhlmann et al, 2015;Wits et al, 2016); flexibility (Brettel et al, 2016;Cox et al, 2016) and technology selection (Newman et al, 2015) allow us to contextualize AM in an actual production system. There are many papers on mechanical characteristics, microstructures and properties (Brugo et al, 2016;Hinojos et al, 2016;Huynh et al;List et al, 2014;<...>…”

From the past decades, increasing attention has been paid to the quality level of technological and mechanical properties achieved by the Additive Manufacturing (AM); these two elements have achieved a good performance, and it is possible to compare this with the results achieved by traditional technology. Therefore, the AM maturity is high enough to let industries adopt this technology in a more general production framework as the mechanical manufacturing industrial one is. Since the technological and mechanical properties are also beneficial for the materials produced with AM, the primary objective of this paper is to focus more on managerial facets, such as the cost control of a production environment, where these new technologies are present. This paper aims to analyse the existing literature about the cost models developed specifically for AM from an operations management point of view and discusses the strengths and weaknesses of all models.

“…A function of heat and mass transfer may be found [2,13], based on the main processing parameters such as the size of the laser beam, the laser power, the scanning speed, the layer thickness, and the hatch spacing [14,15]. Therefore, extensive research has been conducted to draw a correlation between densification and microstructure of IN178 and IN625 AMmade parts.…”

In the frame of additive manufacturing of metals, laser powder-bed fusion is investigated in this paper as an advanced industrial prototyping tool to manufacture Inconel 718 turbine blades at a predesign stage before flow production. Expediting of the evaluation of any upgrade to the part is aimed. To this purpose, possible anisotropy of manufacturing is preliminarily investigated via tensile testing at room and elevated temperature as a function of the sloping angle with the building plate; the normalized strength is given and compared with similar studies in the literature. Positioning and proper supporting in manufacturing are discussed; the parts are further investigated to assess their compliance with the intended nominal geometry.

The growing interest from the industry for lightweight metal components has driven the development of processes that would allow creating lightweight high melting point metals as steels, able to guarantee mechanical characteristics superior to existing foam (typically aluminium), without penalizing one of the characteristics that cell structures have: lightness. Conventional manufacturing methods, such as casting, however, face difficulty in making complex periodic steel structures with designed shape and size and volume fraction. This study evaluates the manufacturability and performance of lightweight 17-4 PH steel components with spherical porosity fabricated via selective laser melting (SLM). Samples were designed and fabricated with the purpose to produce a structure similar to foam. Built samples were characterized in terms of dimensional accuracy, mechanical strength under compression and energy absorbed per unit mass. The designed structures have a designed relative density or volume fraction ranging between 31.1 and 32.8%.
