Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

Innovative 3D metal additive manufacturing (AM) techniques are revolutionizing the biomedical industry, since they enable production of porous structures and patient-customized parts biomedical-grade materials, such as Ti alloys. Surface treatment via plasma electrolytic oxidation (PEO) conventionally manufactured its alloys has been proved an outstanding approach to promote osseointegration im...

Aim: The heterogeneity of the Amyotrophic Lateral Sclerosis (ALS) clinical phenotypes leads to difficulties in early diagnosis. ‘split hand’ sign is defined as thenar muscles that are more prominently affected by hypothenar. In this study, results initial nerve conduction study patients were compared with those controls order increase findings supporting diagnosis.
 Material and Method: Se...

This study aims to generate research data on basis of engineering evidences in terms validation tests for Additively Manufactured (AM) Ti4Al4V parts. It is known that Ti6Al4V alloy broadly used highly-engineered air vehicles and compliance with the aviation-grade specifications. For validation, test parts have been manufactured using EOSM290 DMLS (Direct Metal Laser Solidification) machine unde...

We report the first Vivaldi arrays monolithically fabricated exclusively using commercial, low-cost, 3-D metal printing (direct laser sintering [DMLS]). Furthermore, we developed one of dual-polarized on a triangular lattice, and compare it to square lattice array. The is attractive because has 15.5% larger cell size compared can be more naturally truncated into wide range aperture shapes such ...

Lattice structure topology is a rapidly growing area of research facilitated by developments in additive manufacturing. These low-density structures are particularly promising for their medical applications. However, predicting performance becomes challenging factor use. In this article, four lattice topologies explored suitability as implants the replacement segmental bone defects. The study i...
