Abstract Materials with target load plateaus offer the potential for developing innovative vibration suppression and isolation systems applications such as satellite platforms, submarines, electric vehicles. However, implementing these materials can pose significant challenges. In this study, stair‐stepping mechanical metamaterials programmable are presented, which created via a three‐level (unit, module, 3D object) construction strategy. The strategy inspired by inverse design concept achieves tunability in number properties of within force–displacement profiles metamaterials. This approach even yields appealing response patterns, validated experiments finite element simulations. Promisingly, programming unit from its initial configuration to “zero stiffness” enables excellent performance. Furthermore, two reversible methods proposed switching among various configurations, namely shape memory supporting payload. opens up new possibilities creating customized responses. It also provides opportunities incorporate multimodal capabilities into precision devices.
