3D打印技术在中小学教学中的应用研究

Application Research on Three-dimensional Printing Technology for Junior and Senior High School Teaching

2013年伊始，3D打印技术突然成为人们关注的热点，由工业、建筑、军事等应用领域逐渐走向民用领域。教育领域，特别是基础教育领域应用3D打印技术还处于起步、探索阶段。文章介绍了什么是3D打印技术；3D打印技术在本质上是多媒体技术的延伸，是虚拟现实技术的延伸，它拓展了人的感觉和知觉，促进了人的思维能力的进一步发展；列举了3D打印技术在中小学学科教学中应用的几个案例；3D打印技术目前面临的一些诸如普及慢、成本高、速度慢等局限性。最后指出，3D打印技术作为第三次工业革命的重要标志之一，未来4～5年，必将普遍走进中小学课堂，必将对现有教学产生深刻的影响和变革。

At the beginning of 2013， the three-dimensional Printing (3D printing) technology caught the eyes of everyone. It begins to tend towards from the fields of industry， architecture， military affairs， etc. to the fields of usage for the ordinary people. Three-dimensional printing technology is still in an initial and exploratory stage in the education field， especially in the realm of basic education. This article introduces what is the three-dimensional Printing technology; in fact three-dimensional printing technology is an extendability of multimedia technology， and what’s more， it’s an extendability of virtual reality technology， it not only enlarges human perception but also promotes the further development of the ideation of human; the article shows several cases about three-dimensional Printing technology， which have been used in subject teaching in primary and secondary schools; the article also expounds the limitations of three-dimensional printing technology such as popularization， cost as well as rapidity; in the following 4 to 5 years， three-dimensional printing technology， which is one of the important marks of the third industrial revolution， will go into the classrooms of primary and secondary schools， moreover， it will bring a profound impact and change to the existing teaching.
