Special Issue Information

Dear Colleagues,

Additive manufacturing is a pacemaker technique in the field of manufacturing today. It encompasses the fabrication of a different kind of 3D object by adding both polymers and metallic material layer by layer irrespective of the shape and size (intricate objects). This technology has been the state of the art over the last 20 years, and it is now favored over the conventional manufacturing process for developing complex products with minimal cost and effort. Commonly, additive manufacturing uses modern technology such as CAD, CNC, and simulation software for fabricating different material objects. Additive manufacturing involves various steps while developing the real physical object. The development of a realistic object begins with the selection of raw material, a specific additive manufacturing process, design procedures, and layout section followed by post-processing requirements. Products developed using the additive manufacturing technique have tremendous advantages, such as low material and energy wastage, compared to traditional methods.

The proposed Special Issue will focus on the following topics:

  • Additive manufacturing in the field of aircraft and automobile industries;
  • Solid-state additive manufacturing techniques.
  • Composite materials through additive manufacturing
  • Mechanical, tribological and thermal characterization of additive layers;
  • Design and simulation modeling of additive manufacturing;
  • Residual stresses in additive manufactured components;
  • Process parameters of additive manufacturing techniques;
  • Multi-technology and additive manufacturing;
  • Synthesis of novel materials and composite materials;
  • Special applications in medical and healthcare, nano-additive manufacturing, etc.

The presence of defects in additive manufactured maraging steel is a widespread problem as its dependence on processing parameters significantly influences it. Using X-ray computed tomography, along with optical microscope data limited to 2D images, quantifies the internal porosity present on a compact tension sample typically employed in fatigue testing. The primary goal of this research is to analyse the pores obtained after the fabrication of a compact tension sample and their main definition parameters, such as sphericity, aspect ratio, surface, and volume, and obtain validation of which method is valid for each of the parameters analysed. The current study aims to enhance the understanding of defects in maraging steel samples through non-destructive 3D analysis. Conventional 2D analyses are limited to surface measurements, providing incomplete information. The proposed method will provide a comprehensive understanding of the defects inside the maraging steel sample, thereby improving the reliability of this material for further applications. This study will contribute to academic and industrial communities by providing a novel approach to analysing maraging steel samples and, ultimately, developing improved materials for various applications. The study’s findings reveal that most pores are produced by gases that are trapped in the fabrication process, and keyhole pores only appear near the surface. Full article

In order to enhance the range of processable alloys of laser-based powder bed fusion, reinforced alloys have gained focus. Satelliting is a recently introduced method for adding fine additives to larger parent powder particles using a bonding agent. Satellited particles prevent a local demixing due to size and density effects of the powder. In this study, the satelliting method is used for the additivation of Cr3C2 to AISI H13 tool steel via a functional polymer binder (pectin). The investigation includes a detailed binder analysis and comparison to the previously used PVA binder as well as processability in PBF-LB and the microstructure of the alloy. The results reveal that pectin is a suitable binder for the satelliting process and the demixing behavior that appears when using a simple powder blend can be significantly reduced. However, the alloy is enriched with carbon, which results in austenite being retained. Thus, in future research, a reduced binder content will be investigated. Full article
