近年来，3D打印技术在国内外得到了快速的发展，新的3D打印技术层出不穷，打印速度更快，精度更高，更丰富的打印材料。 3D打印从最初只用来生产原型件到能够直接生产极具竞争力的产品，正在逐渐成为设计革新的源动力。 虽然3D打印全新的生产方式给创新注入了活力，但与此同时，发展中的3D打印技术仍然有许多使用上的限制和工艺上的不足，如何避免不足，充分发挥打印的优势和长处成为创新设计中需要反复探索和研究的问题。 3D打印结构优化与创新设计课程是一门理论结合实践操作的选修性课程，通过理论教学，软件操作，打印设备和工艺的探索等方式把学生引入创新设计的殿堂。 课程将会从三维数据获取与设计、结构优化、工艺设计等方面深入浅出地介绍3D打印产品优化创新的流程和要点。其中结构优化部分重点介绍拓扑优化技术，通过该技术能够获得最佳的打印材料分布，实现产品性能最优设计和轻量化，同时节省打印材料和打印成本，是目前公认的可最大化挖掘3D打印制造潜力的优化技术。 课程希望通过丰富的原理讲解，案例分析，现场动手操作让学生能够了解3D打印从设计到制造的整个过程，达到掌握和运用3D打印技术进行创新设计的教学目标，提高学生思考、解决和探索问题的能力。 In recent years, 3D printing technology has been developed rapidly. New printing method emerges in endlessly, 3D printing is becoming more and more fast, higher precision, and have more abundant printing materials.From prototyping to direct manufacturing,3D printing is becoming a driving force for design innovation. Although the new production mode of 3D printing give innovation new power, at the same time, 3D printing technology still has many limitations in use and technological shortcomings. How to avoid the shortcomings, fully take the advantage of printing has become a problem that needs to be explored in innovative design. The course aims to help students understand the whole process of 3D printing from design to manufacture, apply 3D printing technology to innovative design and improve students'ability to think, solve and explore problems.
