Definitions

• the rigidity may be in a rotational direction.
• the rotational direction may be a direction that rotates along a longitudinal axis of a layer first wall, where the longitudinal axis of a layer of the first wall may be substantially orthogonal (right angled) to the to the first axis of the first wall.
• the rigidity of the layers of the first wall or any subsequent wall may be seen as a rigidity which represents the flexibility of the layer in a rotational direction.
• the one or more layers may deflect away from the first axis of the wall, where a layer may be bonded to another layer, which means that the compression force will cause a torque to be applied to the layer or both layers.
• the wall When pressure is applied to the walls and when the force applied to the wall exceeds a certain limit, the wall will deform, and as the bottom end (second end) of the wall is restricted inside the shoe by the foot facing surface of the outsole, the first end will move in a direction towards the second end, and for this to happen, the wall will deform, by buckling, expanding or other ways, in order to allow the first end to move in a downwards direction.
• the wall may be advantageous that the deform of the wall is unrestricted in at least one direction, i.e. in the direction towards the central axis of the cell.
• the deformed wall is allowed to deform freely into the cell, so that the radius between the wall and the cell is reduced in at least one area.
• the form of the cell e.g. the shape of the cell seen from above or the side, may also influence the deformation of the wall, as a connected wall and the angle of the connection may increase or decrease the resistance of the wall.
• the 3D printed structure may comprise a third layer and optionally further comprises at least a third wall comprising at least a tertiary structural layer and at least a third flexible layer, where the third axis intersects the third layer and the tertiary structural layer.
• the 3D printed structure may be provided with a further wall having a tertiary structural layer, as well as at least a third layer of the 3D printed structure, where the third axis both intersects the third layer, as well as the third structural layer.
• the third wall may provide a further connection to the first and the second wall in order to provide a resilient relationship between the first and second wall, as well as the third wall.
• the increased rigidity of the three structural layers compared to the flexible layers which may surround the structural layers in the walls, may follow the third axis through multiple layers and multiple walls of the 3D printed structure.
• the primary structural layer and the secondary structural layer may be positioned in different layers in the 3D printed structure.
• the primary structural layer and the secondary structural layers may be provided in different layers of the 3D printed structure it may be possible to shift the rigidity of the wall in a diagonal manner from one wall to the other wall, i.e. where the increased rigidity in the second wall is provided in a layer that is lower or higher than the structural layer in the first wall.
• Fig. 2c the same situation is shown, where a compression force has to be applied to the wall 30, where the flexible layer 35 deflects in the direction d and the flexible layer deflects in the direction c2.
• the directions d and c2 are only shown as examples, and the flexible layers can deflect in the same direction, opposite directions, or alternate directions.
• a similar deflection may occur when the number of flexible layers is only two, where the flexible layer may deflect in a direction away from the first axis A in a direction shown by the axis C.
• the 3D printed structure shown in Fig. 3, is formed so that the longitudinal axis D of the layers 51 -58, is substantially centered along the length of the wall 50 in the direction of axis A, i.e. that the axis D intersects the longitudinal axis D of each of the layers.
• the two walls in a single layer create a structural layer, as the two walls 98a, 98a‘ bond with each other and have a higher rigidity than the single wall.
• the hexagons that are only separated by a single wall 98b, 98c, 98e, 98f, create a flexible wall.
• the third layer 209 may yet further be provided with a flexible layer 205 or a structural layer 204 in the direction of axis A, abutting a flexible 205 or a structural layer 204 in the previous layer 208.
