摘要

增材制造(AM)除了众所周知的能够以极大的可行性生产复杂零件、材料最少、不需要昂贵的模具等优点外,还具有不同尺寸的高潜力。社会、环境、健康和教与学是AM可以作为促进经济变革引擎的一些方面的例子,特别关注人口稀少的地区。“教与学”是促进全球变革的关键。将增材制造技术纳入教学过程有两种主要方法:主动和被动集成3D打印。在这项工作中,这两种方法都是通过不同学科的一些经验来考虑的,比如制造过程工程和材料科学。从获取增材制造技术知识和培养增材制造技术技能的主动途径出发,介绍了增材制造技术在材料内部结构晶格生成和铸造工艺中图案制造中的应用。通过这些例子,学生们发展了与增材制造设计、选择合适的材料和打印参数以及后处理任务相关的技能。在被动方法中,即使用这些技术来支持技术科目的学习过程,展示了三个例子:Bravais晶体晶格的空间构型,铸造工艺的设计和auxetic结构的力学行为。这些例子有助于帮助我们的本科生理解需要空间视觉的基本概念,如晶格的例子,通过设计图案,芯盒和铸造分配系统来改进铸造工艺,以及接近高级材料的机械行为,如auxetic结构。这项工作旨在传播AM维度的潜力,如学习和教学,以促进创新领域。

Other Dimensions of Additive Manufacturing: Learning and Development of Technical Skills in Bachelor Subjects
Additive manufacturing (AM) has different dimensions with high potential, apart from the well-known ability to produce complex parts with great feasibility, minimum material, and without the need of expensive dies, among other advantages. Social, Environmental, Health, and Teaching and Learning are some examples of dimensions where AM can serve as an engine to promote economic changes, with special focus in depopulated areas. The “Teaching and Learning” dimension is key to promote global changes. There are two main approaches to incorporating additive manufacturing technologies into teaching and learning processes: active and passive integration of 3D printing. In this work, both approaches are considered through the example of some experiences in subjects of different disciplines such as manufacturing processes engineering and materials science. From the active approach, that is, acquiring knowledge and developing skills on AM techniques, the application of AM to generate crystal lattices of the inner structure of materials and the fabrication of patterns in foundry processes are presented as examples. Through these examples students develop skills related to design for additive manufacturing, selection of suitable materials and printing parameters, and postprocessing tasks. Form the passive approach, that is, the use of these technologies to support the learning process in technical subjects, three examples are shown: Bravais crystal lattices spatial configuration, design of foundry processes, and mechanical behavior of auxetic structures. These examples are useful to help our undergraduates understanding basic concepts that require spatial vision, as is the case of crystal lattices, improve foundry processes through the design of patterns, core boxes and casting distribution systems, and approaching to mechanical behavior of advanced materials, such as auxetic structures. This work aims to disseminate the potential of AM dimensions, such as Learning and Teaching, to boost fields of innovation.
