摘要:

3D打印技术是一种先进的快速成型技术,已给艺术、工程、医学、科学等领域带来巨大变革,在岩石试验中也展现出了良好的应用前景.本文详细介绍了3D打印技术的基本概念、分类和流程,综合分析前人已有的研究,阐述了3D打印技术在岩石试验中的新应用,包括岩石内部结构重构、岩体结构面自由设计和岩体内裂隙动态扩展试验样品制备三个方面.此外利用3D打印技术制作的试样相对于传统的自然界采集的岩样或者是人工合成的类岩石样品,具有得天独厚的优势,例如试验结果可重复性更高,岩石内部结构和应力场的可视化,能打破尺寸效应的限制,也更有助于研究结果的展示和教学,不过3D打印材料现阶段也存在材料强度和精确度的不足.最后对3D打印技术在岩石试验中的应用前景进行展望.

Abstract:

3D printing, shorthand for a host of technologies more broadly described as “rapid prototyping”, is transforming how artists, engineers, doctors, and scientists interact with and understanding 3D data and models. It also looks promising in rock mechanics. This article describes in detail the concept of 3D printing technology and its types and procedure. Based on the comprehensive analysis of the previous research, it illustrates the new application of this technology in rock mechanics, including rock microstructure modeling and reconstruction, joints free designing and specimens with preset cracks manufacturing. In addition, compared with natural rock samples or synthetic rock-like samples, it is suggested that 3D printed samples will bring the advantages of visualization,tangibility,flexibility,repeatability, and effectiveness in rock mechanics. It also has the advantage in breaking the limitation of size effects and being more conducive to present or teach. However, there are also two deficiencies, material strength and brittleness and the accuracy of reconstruction. Eventually, the prospect of 3D printing technology in rock mechanics is forecasted.

Key words: 3D imensional printing, rock mechanics, visualization, joints, cracks
