摘要：
a 3D printed structure of an elastic material having at least a first layer and a second layer, the 3D printed structure comprising: at least a first wall comprising at least a primary structural layer and at least a first flexible layer, at least a second wall comprising at least a secondary structural layer and at least a second flexible layer, where 3D printed structure comprises a third axis, where the third axis intersects the fist and the second layer and where third axis intersects the primary structural layer and the secondary structural layer, where the primary structural layer has a first rigidity and the first flexible layer has a second rigidity, where the first rigidity is larger than the second rigidity.
技术问题语段：
The technical problem addressed in this patent is the need for improved structures that have both flexibility and resilience/spring effect between different walls of the structure, while also allowing for individualization of the flexible layers.
技术功效语段：
The patent text describes a new type of 3D printed structure that is made up of layers of elastic material. These layers have a primary structural layer and a flexible layer that allows for flexibility and impact resistance. The structure also has a third axis that intersects with the first and second layers, creating a resilient mechanical interaction between the walls. This new structure is more flexible and impact-resistant than traditional 3D printed structures, while still maintaining its shape when a force is applied. The technical effect of this new structure is improved flexibility and impact resistance.
