Tooling, especially for prototyping or small series, may prove to be very costly. Further, prototyping of fiber reinforced thermoplastic shell structures may rely on time-consuming manual efforts. This perspective paper discusses the idea of fabricating tools at reduced time and cost compared to conventional machining-based methods. The targeted tools are manufactured out of sand using the Binder Jetting process. These molds should fulfill the demands regarding flexural and compressive behavior while allowing for vacuum thermoforming of fiber reinforced thermoplastic sheets. The paper discusses the requirements and the challenges and presents a perspective study addressing this innovative idea. The authors present the idea for discussion in the additive manufacturing and FRP producing communities.
模具,尤其是用于原型制作或小批量生产的模具,可能成本很高。此外,纤维增强热塑性塑料外壳结构的原型制作可能依赖于耗时的人工操作。本文探讨了与传统机械加工方法相比,以更低的时间和成本制造模具的想法。目标模具是使用粘结剂喷射工艺用沙子制造的。这些模具应满足关于弯曲和压缩性能的要求,同时允许对纤维增强热塑性塑料片材进行真空热成型。本文讨论了相关要求和挑战,并提出了一项针对这一创新想法的前瞻性研究。作者提出这一想法供增材制造和纤维增强塑料生产领域的人士讨论。
