The Use of Additive Manufacturing Techniques in the Development of Polymeric Molds: A Review.

This research-oriented review project provides a comprehensive evaluation of additive manufacturing (AM) techniques utilized in the fabrication of polymeric molds and rapid tooling. Traditional mold manufacturing often involves high costs and long lead times, prompting the integration of 3D printing technologies such as Stereolithography (SLA), Fused Deposition Modeling (FDM), and Selective Laser Sintering (SLS) to produce polymer-based molds. This study systematically analyzes the material selection criteria, focusing on high-temperature photopolymers, thermoplastic composites, and engineering resins capable of withstanding the thermal and mechanical stresses of injection molding or casting processes. Key performance indicators, including dimensional accuracy, surface roughness, thermal conductivity, and mechanical degradation under cyclic loading, are critically evaluated. Furthermore, the

project outlines the current limitations of polymeric molds, such as low thermal dissipation rates and premature mechanical failure, while proposing optimization strategies like conformal cooling channel design and post-curing treatments. By structuring this review, the project offers a methodological framework for selecting appropriate AM processes and polymer materials to optimize rapid tooling workflows in chemical and polymer manufacturing industries.
