The paper reported the results of a study concerned with principle operation 3D printing technology using method selective sintering metallic powders, and taking into account their advantages drawbacks. applying DMLS (Direct Metal Laser Sintering) is presented. On basis performed tests, anisotropy printed materials demonstrated. reasons responsible for this phenomenon are identified. presents s...

The most critical component of Industry 4.0, the new face machinery-manufacturing industry sector, is metal additive manufacturing. Laser-based manufacturing techniques are dominant for today. In this study, alloy studied Ti-6Al-4V, one essential Ti alloys used in more than 50% all commercial applications. Ti-6Al-4V parts produced by biomedical, aerospace-defence industry, and industrial areas ...

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 behaviour, and at the same time ensure high corrosion resistance. Surface modification shot peening is considered suitable for medical devices made 17-4PH st...

Additive manufacturing (AM) is used for the fabrication of solid components complex geometries customized applications. However, AM-fabricated frequently require finishing operations such as abrasive grinding, which causes a different surface characteristic compared to conventionally manufactured components. Thus, it essential study effect process parameters and heat treatment on quality AM bec...
