This disclosure generally relates to computing components with one or more additively manufactured protrusions, systems, and methods of manufacturing and use. More particularly, this disclosure generally relates to additively manufactured protrusions extending from a cosmetic surface.
The sheet 110 may have a thickness 114 between the cosmetic surface and the protrusion surface 112. The thickness may be less than 200 microns, 400 microns, 600 microns, 800 microns, 1 cm, 1.5 cm, 2 cm, or values therebetween. The sheet 110 may be flat. For example, the sheet 110 may be flat to within 100 microns over a 10 cm by 10 cm area, to within 150 microns over a 15 cm by 15 cm area, or to within 50 microns over a 5 cm by 5 cm area.
The sheet 110 may be formed of steel, copper, aluminum, stainless steel, titanium, magnesium, other materials, or alloys thereof. In at least one embodiment, the sheet 110 is formed of 303 half hard stainless steel. The cosmetic surface 116 may be treated. For example, the cosmetic surface 116 may be anodized, polished, plated, painted, or otherwise treated. The sheet 110 may have a yield stress of greater than 70 MPa, 250 MPa, 500 MPa, 600 MPa, 700 MPa, 900 MPa, or values therebetween. The sheet 110 may have a hardness of greater than Rockwell hardness of 60B, 87B, 60C, or values or ranges of values therebetween.
The cosmetic surface of the sheet 110 may be uniform in appearance to the naked eye. For example, observing the cosmetic surface of the sheet 110 may show that the cosmetic sheet is free from blemishes.
The computing component 100 may include one or more protrusions 120. The protrusions 120 may extend from the protrusion surface 112. The protrusions 120 may be additively manufactured to the sheet 110. In at least one embodiment, each protrusion 120 is formed on the sheet 110 and is not separately formed and attached to the sheet 110. The protrusions 120 may have lengths (e.g., length 125, 127).

The protrusion 120-2 may have a base 122 and an end 124. The end 124 may be used for structural support. For example, a separate component may be attached to the end 124. The base 122 may have a cross-sectional width 126-1 and the end 124 may have a cross-sectional width 126-2. The protrusion 120-2 may have a difference in cross-sectional width 126-1 at the base 122 and the cross-sectional width 126-2 at the end 124. As shown the difference may be zero.

If the heat affected zone 118-2 reaches the cosmetic surface 116, the cosmetic surface 116 may become visually and/or structurally modified (e.g., blemished). For example, an area of the cosmetic surface 116 adjacent (e.g., below) the protrusion 120-2 may have a different surface roughness than another area of the cosmetic surface 116 away from the protrusion 120-2. In another example, the area of the cosmetic surface 116 adjacent the protrusion 120-2 may exhibit recrystallization. Heat may, for example, modify (e.g., passivate) the crystal structure of the sheet 110. In another example, the area of the cosmetic surface 116 adjacent the protrusion 120-2 may have a different microstructure than areas away from the protrusion 120-2.

In at least one embodiment, the microstructural texture of the area of the cosmetic surface 116 adjacent the protrusion 120-2 and the microstructural texture of the area of the cosmetic surface 116 away from the protrusion 120-2 may be uniform. In at least one embodiment, the cosmetic surface 116 may be a class A surface. In at least one embodiment, the cosmetic surface 116 has a uniform color.

A third layer 130-3 and successive layers 130 may be added until the protrusion 120-2 reaches a desired height 128. Each layer 130 has a height 138. As shown, the first layer 130-1 has a height 138-1.
The protrusion 120-3 may have a base 122 and an end 124. The protrusion 120-3 may be rounded. The protrusion 120-3 may form an enclosure.

The articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements in the preceding descriptions. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.

For example, any element described in relation to an embodiment herein may be combinable with any element of any other embodiment described herein. Numbers, percentages, ratios, or other values stated herein are intended to include that value, and also other values that are “about” or “approximately” the stated value, as would be appreciated by one of ordinary skill in the art encompassed by embodiments of the present disclosure. A stated value should therefore be interpreted broadly enough to encompass values that are at least close enough to the stated value to perform a desired function or achieve a desired result. The stated values include at least the variation to be expected in a suitable manufacturing or production process, and may include values that are within 5%, within 1%, within 0.1%, or within 0.01% of a stated value.
A person having ordinary skill in the art should realize in view of the present disclosure that equivalent constructions do not depart from the spirit and scope of the present disclosure, and that various changes, substitutions, and alterations may be made to embodiments disclosed herein without departing from the spirit and scope of the present disclosure. Equivalent constructions, including functional “means-plus-function” clauses are intended to cover the structures described herein as performing the recited function, including both structural equivalents that operate in the same manner, and equivalent structures that provide the same function. It is the express intention of the applicant not to invoke means-plus-function or other functional claiming for any claim except for those in which the words ‘means for’ appear together with an associated function. Each addition, deletion, and modification to the embodiments that falls within the meaning and scope of the claims is to be embraced by the claims.
It should be understood that any directions or reference frames in the preceding description are merely relative directions or movements. For example, any references to “front” and “back” or “top” and “bottom” or “left” and “right” are merely descriptive of the relative position or movement of the related elements.
The present disclosure may be embodied in other specific forms without departing from its spirit or characteristics. The described embodiments are to be considered as illustrative and not restrictive. The scope of the disclosure is, therefore, indicated by the appended claims rather than by the foregoing description. Changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
