Abstract
To tackle the challenge of high shrinkage in sintered additively manufactured parts, a novel approach involving the modification of the printing composition through the incorporation of glass fibers was proposed. Experimental evaluations demonstrated the effectiveness of this method, revealing a substantial improvement in the dimensional and geometrical accuracy of the fabricated parts. By incorporating 12 % short glass fibers into the composition, the shrinkage was significantly reduced, achieving an impressive 0.1 %.
期刊介绍：
Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
