Abstract Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, properties of AM products should be modified to increase their strength, anti-wear behavior, and at the same time ensure high corrosion resistance. Surface modification shot peening (SP) is considered suitable for engineering devices made 1...

For analysis of engineering structural materials to withstand harsh environmental conditions, accurate knowledge properties such as flow stress and failure over conditions high strain rate temperature plays an essential role. Such additively manufactured Ti6Al4V(ELI) are not adequately studied. This paper documents investigation the different forms heat-treated samples produced by direct metal ...

PURPOSE The aim of the present paper was a question of structural identification and evaluation of strength parameters of Titanium (Ticp - grade 2) and its alloy (Ti6Al4V) which are used to serve as a base for those permanent prosthetic supplements which are later manufactured employing CAD/CAM systems. METHODS Microstructural tests of Ticp and Ti6Al4V were conducted using an optical microsco...

BACKGROUND DNA from archival formalin-fixed and paraffin embedded (FFPE) tissue is an invaluable resource for genome-wide methylation studies although concerns about poor quality may limit its use. In this study, we compared DNA methylation profiles of breast tumors using DNA from fresh-frozen (FF) tissues and three types of matched FFPE samples. RESULTS For 9/10 patients, correlation and uns...

Marginal and internal adaptation are parameters of crucial importance to the success prosthetic crowns. Automatized process creates an expectative superior or equivalent results compared restorations manufactured ​​by conventional lost-wax technique. The purpose this study was evaluate marginal (cement space) metal-ceramic crown copings produced by (LW) direct metal laser sintering (DMLS) techn...

In this paper, a characterization of an AlSiMg alloy processed by direct metal laser sintering (DMLS) is presented, from the analysis of the starting powders, in terms of size, morphology and chemical composition, through to the evaluation of mechanical and microstructural properties of specimens built along different orientations parallel and perpendicular to the powder deposition plane. With ...
