Sintering Mechanisms in Metal Extrusion-based Sintering-assisted Additive Manufacturing: State-of-the-Art and Perspectives
“Extrusion-based sintering-assisted additive manufacturing (ES-AM) has enabled the fabrication of intricate metal structures, spanning from simple geometries to complex lattice structures. The sintering process plays a vital role in metal densification that requires effective design and optimization of sintering processes for high-quality sintered parts. Notably, sintering behaviors in ES-AM differ from those in traditional methods,

3d printing of a continuous carbon fiber reinforced bronze-matrix composite using material extrusion
“The main objective of this study is to investigate, for the first time, the feasibility of 3d printing a continuous carbon fiber (CCF) reinforced metal matrix composite using a cost-effective material extrusion (MEX) technology. Notably, this paper presents a detailed analysis of the microstructure and mechanical and physical properties of a bronze matrix composite reinforced
Enhanced Phase Change Heat Transfer with Fused Deposition Modeling (FDM) Printed Pit and Pillar (Pi2) Arrays
“Phase change heat transfer, crucial in thermal management systems, can be significantly enhanced through optimized surface structures. This study investigates pool boiling heat transfer enhancement using 3D printed structures with carefully designed pillar and pit geometries. We present a novel approach combining the Dual Rise model with separate liquid–vapor pathways to improve Critical Heat Flux
Establishment of Select Printing Parameters for Low-Cost Fused Deposition Modeling Printed Cast Iron Through Experimental Optimization
“The fused deposition modeling (FDM) form of additive manufacturing provides a low-cost opportunity to quickly create unique parts with complex geometries using a high degree of precision. This is accomplished through a layer-by-layer extrusion of a metallic infused thermoplastic from a heated nozzle onto a build plate, until the 3D part is achieved. The ability
