Laser powder bed fusion (L-PBF) stands out as a promising approach within the realm of additive manufacturing, particularly for the synthesis of CNT-AlSi10Mg nanocomposites. This review delves into a thorough exploration of the transformation in microstructure, the impact of processing variables, and the physico-mechanical characteristics of CNT-AlSi10Mg nanocomposites crafted via the L-PBF technique. Moreover, it consolidates a substantial corpus of recent research, proffering invaluable insights into optimizing L-PBF parameters to attain the desired microstructures and enhanced properties. The review centers its attention on pivotal facets, including the dispersion and distribution of CNTs, the formation of porosity, and their subsequent influence on wear resistance, electrical and thermal conductivity, tensile strength, thermal expansion, and hardness. In line with a logical progression, this review paper endeavors to illuminate the chemical composition, traits, and phase configuration of AlSi10Mg-based parts fabricated via L-PBF, juxtaposing them with their conventionally manufactured counterparts. Emphasis has been placed on elucidating the connection between the microstructural evolution of these nanocomposites and the resultant physico-mechanical properties. Quantitative data culled from the literature indicate that L-PBF-produced parts exhibit a microhardness of 151 HV, a relative density of 99.7%, an ultimate tensile strength of 70×103 mm3N.m, and a tensile strength of 756 MPa.

“…The additive manufacturing (AM) (1)(2)(3)(4) technology is divided into seven categories, among which there are two technologies applied to metallic powder: powder bed fusion (PBF) (5) and laser metal deposition (LMD). The substances manufactured by the PBF technology are rougher and more precise than those made by other mechanical manufacturing processes, such as precision casting, turning, and forging, and complex and integrally formed structures can be produced.…”

The molecular dynamics simulation method with the embedded atom model/Finnis-Sinclair potential was used to investigate solid and hollow spherical platinum (Pt) nanoparticles under different heating rates during the additive manufacturing process. We concluded that the coalescence temperatures of solid and hollow spherical Pt nanoparticles range between 975 and 1450 K and between 561 and 1414 K, respectively. We concluded also that the melting temperatures of solid and hollow spherical Pt nanoparticles range between 1300 and 1535 K and between 1250 and 1500 K, respectively. In this study, we found that the lower the heating rate, the greater the diffusion of Pt atoms. The solid-state sintering of Pt nanoparticles can spontaneously occur at 300 K. We concluded that the melting temperatures of both solid and hollow spherical Pt nanoparticles are still lower than the macroscopic melting point of Pt (2041.4 K).
