FIG. 3 is an enlarged view of the cross-section encompassed by Area 3 shown in FIG. 2. The continuous exterior surface region 52 includes a surface layer 54 (or surface layers). A plurality of intermediate layers 56 is disposed below the surface layer 54 (or in-between surface layers). Although only two intermediate layers 56 are depicted, it should be understood that two or more intermediate layers 56 may be included. Therefore, two or more intermediate layers 56 should be construed as disclosed herein. The surface layer 54 and intermediate layers 56 may be formed of discrete or distinct layers of material. The layers of material may be formed by an additive manufacturing processes as described above.
The roof panel 12 and one or both of the first bodyside panel 14 and the second bodyside panel 16 may define successive layers of material that are sequentially arranged in a stacked formation that extends from the bottom region 24 of the first bodyside panel 14 (and/or bottom region 40 of the second bodyside panel 16) to a top surface 58 of the roof panel 12, including the top region 22 of the first bodyside panel 14 (and/or top region 38 of the second bodyside panel 16) and the roof panel 12.
Alternatively, the roof panel 12 and one or more of the elements of the first bodyside panel 14 and/or the second bodyside panel 16 (i.e., A-pillar, B-pillar, C-pillar, D-pillar, roof rail, and/or rocker panel) may define successive layers of material that are sequentially arranged in a stacked formation that extends from a bottom region of the specific element to top surface 58 of the roof panel 12 including a top region of the specific element and the roof panel 12.
Each of the discrete layers of material may be substantially uniform in thickness. Substantially uniform in thickness may refer to plus or minus 10% of a uniform thickness, T. This includes any incremental value between 90% and 110% of the uniform thickness, T. Each of the discrete layers of material may be substantially uniform in height. Substantially uniform in height may refer to plus or minus 10% of a uniform height, H. This includes any incremental value between 90% and 110% of the uniform Height, H. Although the discrete layers of material are shown to have a square cross-sectional shape, it should be understood that the cross-sectional of the discrete layers of material may have any desirable shape. For example the cross-sectional shape of the discrete layers of material may be a rectangular, circular, square or rectangular with rounded corners, shaped like a parallelogram, etc.
The enlarged view of the cross-section encompassed by Area 3 depicts the layers of material that extend in a direction that is into the paper upon which the figures are depicted (i.e., the layers of material extending in a direction that is perpendicular to the plane upon which the figures are depicted). Alternatively, layers of material may extend in a direction that is within the plane defined by the paper or at any incremental angle between the plane defined by the paper and the direction that is perpendicular to the plane defined by the paper. In addition, although each layer of material is shown to extend in the same direction, alternative embodiments may include layers that extend in different or alternating directions. For example, alternating layers may extend in directions that are perpendicular to each other.
The words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. As previously described, the features of various embodiments may be combined to form further embodiments that may not be explicitly described or illustrated. While various embodiments could have been described as providing advantages or being preferred over other embodiments or prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art recognize that one or more features or characteristics may be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. As such, embodiments described as less desirable than other embodiments or prior art implementations with respect to one or more characteristics are not outside the scope of the disclosure and may be desirable for particular applications.
