High-detail 3D printable model of a regal men's signet ring featuring a central royal crown emblem, decorative filigree wire framing, and detailed crossed swords on the side shoulders. Engineered specifically for high-end jewelry manufacturing, lost-wax casting, and rapid prototyping.

The model features clean, manifold geometry optimized for seamless digital rendering and physical production. Designers can utilize the included source file for custom finger size adjustments or personal engraving adaptations.

Dimensions: Inner diameter 17.58 mm, top plate width 20.82 mm, band height 11.03 mm.

Volume: Approximately 717 cubic millimeters for precise precious metal mass estimation.

Included Formats: STL (polygon mesh) and 3DM (NURBS source file).

Manufacturing InstructionsCAD Modification: Open the 3DM file in Rhino or compatible jewelry software to scale the ring inner circumference to match exact finger sizing charts.

Rapid Prototyping: Utilize a high-precision SLA or DLP 3D printer with castable photopolymer resin. Recommended layer height is 0.03 mm or finer to maintain sharp relief on the crown beads and sword elements.

Casting Preparation: Position optimal sprues onto the heavier shank sections to ensure smooth metal flow during vacuum casting. Execute a thorough burnout cycle suited for jewelry resins.

Metal Pouring: Recommended for casting in precious metals including yellow gold, white gold, platinum, and sterling silver.

Post-Processing & Polishing: Clean up flash and support attachment points. Apply chemical blackening or enamel to the recessed background areas to enhance contrast, followed by precision hand-polishing of the raised design elements.
