In recent years, 3D printing has emerged as a promising technology in energy storage, particularly for the fabrication of Li-ion battery electrodes. This innovative manufacturing method offers significant material composition and electrode structure flexibility, enabling more complex and efficient designs. While traditional Li-ion battery fabrication methods are well-established, 3D printing opens up new possibilities for enhancing battery performance by allowing for tailored geometries, efficient material usage, and integrating multifunctional components.

- This study focuses on the properties of Inconel 718/Ti6Al4V multi-material samples with a Cu and Nb interlayer produced using selective laser melting (SLM).
- It investigates the microstructure, chemical composition, phase composition, and hardness, revealing island macro-segregation at interfacial zones and distinct transitions in chemical composition.
- The findings indicate that while no new phases were formed, there were notable changes in microhardness and the ultimate tensile strength of the samples was found to be 910 MPa.
Multi-material can have functional properties, which are not typical for the materials of which they are composed (for instance, shape-changing effect). This can be used in robotics, micromachines, aerospace, and other fields. In this work, the 316L/FeNi36 multi-material produced by selective laser melting was investigated.

- Ion implantation in diamonds is crucial for creating conductive microstructures and isolated photon emitters, with emission lines HR1 and HR2 observed around 536 nm and 560 nm.
- The study involved a thorough examination of helium-related optical centers in natural single-crystal type IIa diamonds, using a 700 nm-thick layer subjected to multiple-energy helium ion implantation and subsequent annealing at various temperatures.
- Results revealed over a dozen unique photoluminescence centers within the 530-630 nm range, emphasizing the impact of annealing on the spectra and identifying specific bands related to interstitial defects in diamonds.
This paper investigated the influence of titanium carbide (TiC) content on the processing, microstructure, mechanical and tribological properties of Inconel 718/TiC composites produced by binder jetting additive manufacturing. It was found that increasing the amount of TiC required an increase of the drying intensity during printing due to a decrease in the thermal conductivity of the powder mixture. The sintering process also depended on the TiC content.
