The main aim of the presented tests was to assess the possibility of using 3D printing and casting material to produce casting molds and prototypes, especially in production of existing models. The analysis was based on the assessment of dimensional accuracy and quality of the surface layer of a finished prototype and the intermediate elements made during the production process. The mold was made using the PolyJet Matrix additive technology, and then a silicone mold was cast which was used to prepare a finished sample for testing in accordance with the design assumptions. Based on the results of metrological measurements, the phenomenon of technological inheritance in terms of error transfer in the foundry industry was evaluated. The measurements obtained suggest that in case of casting process, the hereditary features are transferred from individual casting processes, which is especially prominent in the case of surface texture quality. This confirms the occurrence of the phenomenon of the so-called technological inheritance and the need to analyze it. The results of the tests can be a guide for technologists who design molds, core boxes, and casting models, concerning the corrections (shrinkage) that need to be introduced at the design stage in order to obtain a product (casting) of satisfactory dimensional accuracy and quality of the surface layer. The result can also be useful for casting materials reinforced with glass fiber, carbon fiber, which are common materials in 3D printing and textile industry.

使用 3D 打印的塑料铸件设计指南

所提出测试的主要目的是评估使用 3D 打印和铸造材料生产铸模和原型的可能性，尤其是在现有模型的生产中。该分析基于对成品原型表面层的尺寸精度和质量以及生产过程中制造的中间元件的评估。该模具使用 PolyJet Matrix 添加剂技术制成，然后浇铸硅胶模具，用于根据设计假设制备用于测试的成品样品。根据计量测量结果，对铸造行业技术传承在误差转移方面的现象进行评价。获得的测量结果表明，在铸造过程中，遗传特征是从单个铸造过程中转移而来的，这在表面纹理质量的情况下尤为突出。这就印证了所谓的技术继承现象的发生和分析的必要性。测试结果可为设计模具、芯盒和铸件模型的技术人员提供指导，以指导在设计阶段需要引入的校正（收缩）以获得令人满意的尺寸精度的产品（铸件）和表面层的质量。结果也可用于铸造用玻璃纤维、碳纤维增强的材料，这些材料是 3D 打印和纺织行业的常见材料。这就印证了所谓的技术继承现象的发生和分析的必要性。测试结果可为设计模具、芯盒和铸件模型的技术人员提供指导，以指导在设计阶段需要引入的校正（收缩）以获得令人满意的尺寸精度的产品（铸件）和表面层的质量。结果也可用于铸造用玻璃纤维、碳纤维增强的材料，这些材料是 3D 打印和纺织行业的常见材料。这就印证了所谓的技术继承现象的发生和分析的必要性。测试结果可为设计模具、芯盒和铸件模型的技术人员提供指导，以指导在设计阶段需要引入的校正（收缩）以获得令人满意的尺寸精度的产品（铸件）和表面层的质量。结果也可用于铸造用玻璃纤维、碳纤维增强的材料，这些材料是 3D 打印和纺织行业的常见材料。关于需要在设计阶段引入的校正（收缩）以获得具有令人满意的尺寸精度和表面层质量的产品（铸件）。结果也可用于铸造用玻璃纤维、碳纤维增强的材料，这些材料是 3D 打印和纺织行业的常见材料。关于需要在设计阶段引入的校正（收缩）以获得具有令人满意的尺寸精度和表面层质量的产品（铸件）。结果也可用于铸造用玻璃纤维、碳纤维增强的材料，这些材料是 3D 打印和纺织行业的常见材料。
