The production of rapid tools for plastic molding, sheet metal forming, and blanking has always been a critical and important goal for applied research, and a very large number of alternative methods have been proposed over the decades for their production. Among these methods, the use of extrusion-based additive manufacturing (EAM), such as fused filament fabrication (FFF) or similar technologies, has not been frequently considered and needs to be explored extensively. EAM is generally considered a low-cost, low-quality, low-performance class of AM and not suited to produce real functional parts, but only for aesthetical prototypes. However, the capabilities of EAM technologies have greatly evolved and now it is possible to extrude a wide range of materials such as polymeric materials including both the low strength polymeric materials (such as nylon or PLA) and the high strength polymeric materials (such as PEI and PEEK), metals (such as tool steel), and even ceramics (such as zirconia). Starting from an extensive literature review, the purpose of the present paper is to further demonstrate the potential applicability and versatility of EAM as a rapid tool manufacturing technology for different applications in shearing, bending, deep drawing, and injection molding.
用于塑料成型、钣金成型和冲裁的快速工具的生产一直是应用研究的关键且重要目标，几十年来人们提出了大量替代方法来生产此类工具。在这些方法中，基于挤出的增材制造（EAM），如熔丝制造（FFF）或类似技术，并未经常被考虑，需要进行广泛探索。EAM通常被认为是一类低成本、低质量、低性能的增材制造方式，不适合生产实际功能部件，仅适用于美学原型。然而，EAM技术的能力已大幅提升，现在可以挤出多种材料，如包括低强度聚合物材料（如尼龙或聚乳酸）和高强度聚合物材料（如聚醚酰亚胺和聚醚醚酮）在内的聚合物材料、金属（如工具钢），甚至陶瓷（如氧化锆）。通过广泛的文献综述，本文旨在进一步证明EAM作为一种快速工具制造技术在剪切、弯曲、拉深和注塑等不同应用中的潜在适用性和多功能性。
