众所周知，气缸屈曲对小的几何缺陷非常敏感。这是在设计过程中使用可拆卸因素的根本动机，特别是在最小重量是关键设计目标的情况下，例如美国国家航空航天局（NASA）已确立的一种方法。这不仅对这种常见的结构承重配置的实际设计提出了挑战，而且对精心控制的实验室环境也提出了挑战。 3D 打印（增材制造）的最新发展为对圆柱体屈曲进行相对高保真度的实验提供了一个有吸引力的实验平台。然而，除了几何精度之外，这种方法还存在许多缺点，本文旨在描述与在圆柱屈曲中使用 3D 打印相关的挑战和机遇，并特别探讨平衡配置的鲁棒性。本文是主题“冲击敏感壳的探测和动力学”的一部分。
Cylinder buckling is notoriously sensitive to small geometric imperfections. This is an underlying motivation for the use of knock-down factors in the design process, especially in circumstances in which minimum weight is a key design goal, an approach well-established at NASA, for example. Not only does this provide challenges in the practical design of this commonly occurring structural load-bearing configuration, but also in the carefully controlled laboratory setting. The recent development of 3D-printing (additive manufacturing) provides an appealing experimental platform for conducting relatively high-fidelity experiments on the buckling of cylinders. However, in addition to geometric precision, there are a number of shortcomings with this approach, and this article seeks to describe the challenges and opportunities associated with the use of 3D-printing in cylinder buckling in general, and probing the robustness of equilibrium configurations in particular.This article is part of the theme issue 'Probing and dynamics of shock sensitive shells'.
