“…Mechanical, chemical, and microstructural properties are evaluated in comparison to new AM technologies, for example, the selective laser melting (SLM) in relation to conventional techniques as lost wax casting [21][22][23]. In this way, the preparation of medical and dental components provides customized final components with high mechanical properties, compared to conventional techniques (see Figure 1) [24].…”

This chapter seeks to compare the properties of samples manufactured by additive manufacturing (AM) by the selective laser melting (SLM) technology and compare with the precision casting (PC) processes using the Co-Cr-Mo (ASTM F75) alloy to manufacture of dental prosthesis. This AM process can be manufactured three-dimensional models by means of a laser beam that completely melts particles of powder deposited layer by layer. However, it is still relevant to know the properties of: performance, dimensional, mechanical and microstructural of this laser melting process and compare with a convencional process. The results of mechanical evaluation showed that the SLM technique provides superior mechanical properties compared to those obtained by the PC technique. It is possible to verify that the consolidation by SLM technique results in lower presence of porosity than PC technique. In addition, PC samples presented a gross dendritic microstructure of casting process. Microstructural analysis of SLM samples results in a characteristic morphology of layer manufacturing with ultrafine grains and a high chemical homogeneity. In this way, the development of the present study evidenced to improve the manufacture of customized components (copings) using the SLM technology.

“…This lag has arisen because in manufacturing, design involves planning models and conceiving them on a screen with CAD software; conversely, in medicine, most 3D printing involves reverse engineering-creating objects which already exist physically in the patient (14). Therefore, converting data in the form of a stack of computed tomography (CT) or magnetic resonance imaging (MRI) slices into an STereoLithography (STL) file format readable by a CAD software requires pre-processing (15).…”

Three-dimensional (3D) printing is a process which generates prototypes from virtual objects in computer-aided design (CAD) software. Since 3D printing enables the creation of customized objects, it is a rapidly expanding field in an age of personalized medicine. We discuss the use of 3D printing in surgical planning, training, and creation of devices for the treatment of aortic diseases. 3D printing can provide operators with a hands-on model to interact with complex anatomy, enable prototyping of devices for implantation based upon anatomy, or even provide pre-procedural simulation. Potential exists to expand upon current uses of 3D printing to create personalized implantable devices such as grafts. Future studies should aim to demonstrate the impact of 3D printing on outcomes to make this technology more accessible to patients with complex aortic diseases.

The objective of this work was to study the mechanical properties and microstructural characterization of specimens of the Co-Cr-Mo alloy obtained by additive manufacturingselective laser melting (SLM) and precision casting aiming at the manufacture of dental prostheses. The following steps were carried out on Co-Cr-Mo gas-atomized powders: 1) investigation of the physical, chemical and thermal properties of atomized powders in different grain sizes (denominated: D1 <15 μm, D2 20-50 μm and D3 > 75 μm); 2) the consolidation of standard specimens via consolidation techniques; 3) characterization of consolidated by analysis of: cytotoxicity, porosity, X ray diffraction and dilatometry; 4) mechanical characterization of tensile, 3 point bending, hardness (macro and micro Vickers) tests and microstructural characterization (optical and scanning electron microscopy). In general, the results observed were: the grain size D2 (20-50 μm) is the one that best fits in the analysis of packaging, for the consolidation by SLM; the biocompatibility of the samples obtained a positive result for both processing techniques; the mechanical evaluation of the specimens shows that the SLM technique provides superior mechanical properties (yield stress, rupture stress, maximum stress, elongation and hardness), compared to those obtained by the precision casting technique; the microstructure obtained by the SLM process results in an ultrafine grains with high chemical homogeneity, differentiated by the gross dendritic microstructure in the casting process. In this way, the development of the present study evidenced superior quality in manufacturing customized dental components (copings) by SLM technique compared to precision casting.
