TL;DR: In this paper, the effect of powder recycling on the microstructure, chemical composition, porosity, roughness, and tensile properties of printed parts was investigated in the context of laser powder-bed fusion additive manufacturing.

TL;DR: In this article, the development of a graphene/silver nanoparticle (Ag NP) ink and its deployment in an aerosol-jet additive manufacturing system in order to print highly conductive and flexible graphene/Ag patterns for flexible printed electronics was addressed.

TL;DR: In this article, a physics-based process model of laser powder-fed additive manufacturing (LPF-AM), a class of directed energy deposition, is established, which can perform an efficient prediction of the melt pool dimension, wetting angle, dilution, process heating/cooling rates and clad 3D profiles from single-track to multi-track and multi-layer deposition, and has the potential to be employed for the fast process optimization and controller design.

TL;DR: Physical, chemical, and mechanical characterizations of porous titanium implants made by an additive manufacturing method are described to gain insight into the correlation of process parameters and final physical properties of implants used in orthopedics.

TL;DR: A comprehensive review of the state-of-the-art systems in additive manufacturing of functionally graded materials (FGM) through the LDED process is provided in this article, which highlights the opportunities and the challenges associated with each metallic system.
