The inner band 201, inherent in its original materialized design, has two annular protrusions 203 or lips to form an annular channel 204. The outer band 202, also inherent in its original materialized design, has an annular protrusion 205, complementary to the channel 204. Both the annular protrusions 203 (and consequently the channel 204) and the annular protrusion 205 have a 60° angle incline in relation to the bottom of the ring. There is a gap between the inner band 201 and the outer band 202, there is no fusion between them.

FIG. 8 shows only the supports 206 closest to the section-plane to demonstrate how the inner band 201 and the outer band 202 can be printed as two separate units.

DETAILED DESCRIPTION

FIGS. 10, 11, 12—Third Embodiment

(17) FIG. 10 shows a third embodiment of a ring with two bands, a partially materialized inner band 301 and a partially materialized outer band 302. The inner band 301 has an annular channel 303, which is aligned to an annular channel 304 of the outer band 302. Both the annular channels 303 and 304 have at most 60° angle inclines in relation to the bottom of the ring. FIG. 11 shows a plurality of ball bearings 305 inserted into the aligned channels 303 and 304. The materization of the ring then continues, FIG. 12 shows the bearings 305 now trapped between a completed inner band 305 and a completed outer band 306.

A Method of Fabrication

FIGS. 1-4—First Embodiment

(18) In order to process the materialization of the outer band 102 around the inner band 101, this embodiment will be 3D printed using the laser-sintering or laser-melting methods, and so its design must respect the tolerances of the printer that relate to the necessity of using support material for overhanging surfaces. Typically, a printer has a tolerance of about 30° relative to the horizontal that can materialize an ascending protruding layer without the need of support material. Therefore, the protrusion's 103 and channel's 104 protruding inclines will be able to print without the need for supports.

(19) Printer manufacturers recommend that any object be tilted about 10° to avoid printing defects along the bottom surface. If the bands 101 and 102 are tilted 10° in preparation for printing, then the bands' inclines and declines have a 35° angle to the horizontal within the recommended minimum 30° tolerance of the printer. After the ring is materialized, all support material is removed and discarded. In its finished stage, the inner band 101 and outer band 102 will be securely interlinked together by the design of the inner band's 101 annular protrusion 103 and the complementary design of the outer band's 102 annular channel 104, but allowing the outer band 102 to revolve around the inner band 101, as the inner band 101 and outer band 102 are not fused together.

A Method of Fabrication

FIGS. 5-9—Second Embodiment

(20) In order to process the materialization of this embodiment, printer angle tolerances have been considered for this embodiment as well. Tilting the inner band 201 and outer band 202 10° for printing recommendations will keep the rings within the 30° overhang tolerance of the printer. Supports will not be necessary for any overhangs, thus being able to print the inner band 201 and outer band 202 simultaneously with the inner band 201 inside the outer band 202 as depicted in FIG. 7, thus avoiding the need to bend or fasten one band to the other post-materialization. The supports 206 that are attached to the bottom of the inner band 201 and outer band 202 are to be removed and discarded. In its finished stage, the inner band 201 and outer band 202 will be securely interlinked together by the design of the inner band's 201 annular protrusions 203, the resulting channel 204 of said protrusions, and the complementary design of the outer band's 202 annular protrusion 205, but allowing the outer band 202 to revolve around the inner band 201, as the inner band 201 and outer band 202 are not fused together.

CONCLUSIONS, RAMIFICATIONS, AND SCOPE

(21) The reader will see that each embodiment described above achieves the main goals of the invention, that is, to make a spinner ring of two bands that are materialized simultaneously, in an interlinked formation, thus avoiding the need to bend or fasten the bands together, which could lead to a compromised integrity of the material or its assembly. As no bending nor seaming of the ring is necessary in its construction, any motifs drafted on the ring in its design phase will have no risk of being warped or disturbed in that process, and the bands do not need to be uncomfortably thick.

(22) For accuracy and in order to print a ring on a 3D printer, its model must be designed on the computer. There will be no alteration of its design post-printing for the purpose of producing the interlinking or spinning functions.

(23) As for the embodiments' materials, the bands can be made with any material that a 3D printer can print with. Most commercial laser-sintering and laser-melting systems use powdered materials like aluminum, stainless steel, and titanium, and there are several printers that use precious metals, such as gold, silver, and platinum. Although rings made of resin or plastic may have a shorter life span due to the destructive warmth of body heat, stereolithography printers can make these rings. It is conceivable that one can use the resulting resin or plastic-based rings to make metal rings using the lost-wax metal casting method.

(24) While my above descriptions contain many specifics, they should not be construed as limitations on the scope, but rather as an exemplification of several embodiments thereof. Many other variations are possible. For example, both embodiments are designed with protrusions 103 and 203 that wrap along the entire band. The form of these protrusions do not have to wrap along the entire band, but can be substituted by tabs, blocks, or bars of protrusions, that are positioned along the circumference of the band like a dashed or dotted line within its complementary channel of the other band, strategically positioned to prevent the bands from separating.

(25) Another possible variation of the embodiments is to design either the inner bands 101 and 201, or outer bands 102 and 202 with cavities that penetrate from the outer surface of the ring to the inside surface. The existence of such cavities could consequently allow any protrusions in the gap between the bands to have an overhang with supports, as the jeweler now has access to the gap between the two bands and could remove the supports through the cavities.

(26) Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
