The computing component includes a cosmetic prefabricated sheet of material. In some embodiments, the cosmetic prefabricated sheet of material may have a cosmetic surface and a protrusion surface. The computing component includes a protrusion extending from the protrusion surface of the cosmetic prefabricated sheet of material. In some embodiments, the cosmetic surface of the cosmetic prefabricated sheet of material is uniform in appearance to the naked eye. In some embodiments, the protrusion may have a base and an end. The base may have a cross-sectional width and the end may have a cross-sectional width. A difference in the cross-sectional width of the base and the cross-sectional width of the end may be less than 250 microns. ## Claims ### Claim 1 A computing component, comprising: a cosmetic prefabricated sheet of material having a cosmetic surface and a protrusion surface; and a protrusion formed on the protrusion surface of the cosmetic prefabricated sheet of material by Selective Laser Melting (SLM) to form a plurality of layers including an innermost layer of the protrusion and an outermost layer of the protrusion, and wherein a difference in the cross-sectional width across a height of the protrusion is less than 250 microns. ### Claim 2 (depends on 1) The computing component of claim 1, wherein the protrusion and the cosmetic prefabricated sheet of material exhibit a microstructural bond. ### Claim 3 (depends on 1) The computing component of claim 1, wherein the cosmetic surface does not exhibit recrystallization. ### Claim 4 (depends on 1) The computing component of claim 1, wherein an area of the cosmetic surface beneath the protrusion and an area of the cosmetic surface adjacent the protrusion have the same microstructural texture. ### Claim 5 (depends on 1) The computing component of claim 1, wherein the cosmetic surface has an average surface roughness of less than 2 μm Ra. ### Claim 6 (depends on 1) The computing component of claim 1, wherein the cosmetic prefabricated sheet of material has a thickness less than 2 mm. ### Claim 7 (depends on 6) The computing component of claim 6, wherein the protrusion and the cosmetic prefabricated sheet of material form a heat affected zone that does not extend through the sheet to the cosmetic surface. ### Claim 8 (depends on 7) The computing component of claim 7, wherein a distance between the heat affected zone and the cosmetic surface is greater than 20 μm. ### Claim 9 (depends on 8) The computing component of claim 8, wherein the protrusion comprises a Faraday shield. ### Claim 10 (depends on 1) The computing component of claim 1, wherein the cosmetic prefabricated sheet of material is flat to within 100 microns over a 10 cm by 10 cm area. ### Claim 11 (depends on 1) The computing component of claim 1, wherein the protrusion includes a three-dimensional contour. ### Claim 12 A computing component, comprising: a cosmetic prefabricated sheet of material; and a protrusion formed on a protrusion surface of the cosmetic prefabricated sheet of material by Selective Laser Melting (SLM) to form a plurality of layers including an innermost layer of the protrusion and an outermost layer of the protrusion, the protrusion having a base and an end, the base having a cross-sectional width and the end having a cross-sectional width, a difference in the cross-sectional width of the base and the cross-sectional width of the end being less than 250 microns. ### Claim 13 (depends on 12) The computing component of claim 12, wherein the protrusion has a height from the base to the end of greater than 600 microns. ### Claim 14 (depends on 12) The computing component of claim 12, wherein the protrusion forms an L-shape with an orthogonal corner as viewed from above the protrusion surface. ### Claim 15 (depends on 12) The computing component of claim 12, wherein the protrusion forms a boss. ### Claim 16 (depends on 15) The computing component of claim 15, wherein the protrusion includes a support protrusion that forms a straight section connected to the protrusion that forms the boss. ### Claim 17 (depends on 12) The computing component of claim 12, wherein the cosmetic prefabricated sheet of material has a yield stress of greater than 500 MPa. ### Claim 18 (depends on 12) The computing component of claim 12, wherein the cosmetic prefabricated sheet of material has a hardness of greater than 50 Rockwell Hardness B. ### Claim 19 (depends on 12) The computing component of claim 12, wherein the cosmetic prefabricated sheet of material is cold worked. ### Claim 20 A computing device, comprising: a cosmetic prefabricated sheet of material having a cosmetic surface and a protrusion surface; an electronic component connected to the cosmetic prefabricated sheet of material; and a protrusion extending from the protrusion surface of the cosmetic prefabricated sheet of material, the protrusion having a base and an end, the base having a cross-sectional width and the end having a cross-sectional width, a difference in the cross-sectional width of the base and the cross-sectional width of the end being less than 250 microns, wherein the protrusion shields an electronic component. ### Claim 21 (depends on 20) The computing device of claim 20, wherein the protrusion grounds the electronic component to the cosmetic prefabricated sheet of material.
