Applications of the Selective Laser Melting Technology in the Industrial and Medical Fields

Abstract

The existence of an MCP Realizer II SLM 250 equipment at the National Centre of Innovative Manufacturing from the Technical University of Cluj-Napoca (TUC-N) facilitated the starting of different research activities in this field at TUC-N with the aim of improving the Selective Laser Melting (SLM) process capability for a better transfer of the technological gained knowledge to different partners from the industrial and medical fields. Reaching this goal has been also facilitated by the fact that in the period 2010-2013 at the Technical University of Cluj-Napoca, within a postdoctoral project financed by European Commission (E.U.), it was possible to activate with the program entitled "Research regarding the manufacturing of metallic parts by Selective Laser Melting (SLM) technology." Part of the results obtained in this postdoctoral program are presented within this chapter of the book, being addressed not only to the engineers, PhD students, researchers, medical doctors, but also to anyone who might be interested about this Additive Manufacturing (AM) method and its possible applications in the industrial and medical fields.

Structure, Texture and Phases in 3D Printed IN718 Alloy Subjected to Homogenization and HIP Treatments

“…In this method, laser beam selectively melts the surface of a metallic powder to create a fully-dense (close to 99.7%) solid structures with mechanical properties comparable to those achieved by wrought or casting processes, depending on the initial powder composition and process parameters [1,2]. Besides the design freedom capabilities, the reduced manufacturing time and…”

“…Selective laser melting (SLM) process is the most widely used process for additive manufacturing (AM) of complex and customized parts in different industries, such as aerospace and automotive sectors and in the medical field [1]. In this method, laser beam selectively melts the surface of a metallic powder to create a fully-dense (close to 99.7%) solid structures with mechanical properties comparable to those achieved by wrought or casting processes, depending on the initial powder composition and process parameters [1,2].…”

Additív gyártástechnológiák katonai alkalmazásának vizsgálata, különös tekintettel a katonai elektronika területére

“…Ugyanakkor a fentiekből adódik, hogy az elérhető maximális felbontást a projektor felbontása határozza meg, azaz általában korlátozza, ami például egy "full HD" projektor esetében 1080p. [6] A szelektív lézeres szinterezés (SLS 8 ) technológiát az 1980-as évek legvégén fejlesztette ki Carl Deckard, majd 2001-ben a 3D Systems vásárolta fel azt. Ez az eljárás a korábban említettektől eltérően már finomszemcséjű por állagú alapanyaggal dolgozik.…”

Topography and wettability characterization of surfaces manufactured by SLM and treated by chemical etching

“…The same operation is repeated on all the slices composing the object, allowing the layer-by-layer manufacturing process. Such a process can be used for various applications, such as rapid prototyping, the manufacturing of spare parts, the creation of molds [4], etc. In particular, this process could let obtain very promising applications in the biomedical technologies.…”
