Abstract

Additive manufacturing, especially 3D printing, has emerged as an innovative solution for producing injection molds for thermoplastics, enabling time and cost reduction and greater design flexibility. This study presents a Systematic Literature Review (SLR) aiming to analyze the contributions, limitations, and trends of this technology in the industrial context. The methodology followed the PRISMA 2020 protocol, ensuring rigor in the selection and analysis of data. The search was conducted in the ResearchGate, Portal de Periódicos CAPES, IBICT, SciELO Brasil, UFSC Institutional Repository, and ScienceDirect databases, using keywords such as "3D printing", "rapid tooling", and "injection molding". Initially, 100 studies were identified; after abstract screening, 35 were pre-selected and, following inclusion criteria that considered works published between 2015 and 2025 in English or Portuguese focused on the manufacturing of molds or cavities by 3D printing for thermoplastic injection, 10 studies were selected for final analysis, excluding works outside the scope, incomplete, or duplicated. The results show that 3D printing enables rapid prototyping, hybrid mold fabrication, integration of conformal cooling channels, and the use of recycled materials, bringing gains in efficiency, sustainability, and production flexibility. Despite advances, gaps remain in durability, thermal resistance, methodological standardization, and economic evaluation, indicating the need for further studies to consolidate the application of additive manufacturing in tooling on an industrial scale.
