Claims

A 3D printed structure of elastic material having at least a first wall and a second wall, comprising:
The first wall and the second wall are configured and adapted to deform when a force is applied to the first wall and/or the second wall in the direction of a first axis. configured to return to its original configuration when said force applied thereto is removed;
The 3D printed structure comprises:
at least one first layer having a first wall and a second wall, wherein the first wall within the first layer comprises at least one primary structural layer; the first layer, wherein the second wall in the first layer comprises a first flexible layer;
at least one second layer having a first wall and a second wall, wherein the first wall within the second layer comprises a second flexible layer; and the second layer;
the primary structural layer has a first stiffness;
the first flexible layer has a second stiffness;
The 3D printed structure, wherein the first stiffness is greater than the second stiffness.

3. The 3D printed structure of claim 1, wherein the first layer abuts the second layer along a first axis.
