Investigation of ۳D-printed polymers: A focus on material selection, Processing Methods, and Emerging applications and potentials, Mini Review

The advancement of additive manufacturing technologies has positioned ۳D-printed polymers as a transformative force in modern manufacturing, enabling customized, lightweight, and complex structures across multiple industries. This article provides an in-depth exploration of polymer materials used in ۳D printing, focusing on material selection criteria, processing techniques, emerging applications, and future potential. Material categories, including thermoplastics, thermosets, composites, and biodegradable polymers, are examined, emphasizing their mechanical, thermal, and chemical properties influencing printing performance and end-use functionality. Processing methods such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), and Digital Light Processing (DLP) are critically compared in terms of resolution, mechanical strength, build speed, and cost efficiency. Emerging applications in sectors such as biomedical engineering, aerospace, automotive manufacturing, electronics, and sustainable construction are analyzed using recent case studies and market data from ۲۰۲۰ to ۲۰۲۵. The review also highlights the integration of advanced technologies, including multi-material printing, and the development of recyclable and bio-based polymers to address environmental concerns. A forward-looking discussion considers challenges related to scalability, standardization, and material performance under real-world operating conditions. By combining technical insights with market analysis, this paper aims to guide researchers, engineers, and decision-makers in understanding the current landscape and identifying opportunities for innovation in ۳D-printed polymer technologies.
