Como JINGYING pode fazer prototipagem CAD/3D de acordo com a imagem da sua joia de prata

Introdução

In the modern jewelry industry, Design auxiliado por computador (CAD) e a prototipagem 3D revolucionaram a forma como as joias personalizadas são criadas. Jingying, uma empresa profissional de fabricação de joias, é especializada em transformar clientes’ ideias de joias de prata em modelos CAD precisos e protótipos impressos em 3D. This article explores the step-by-step process of how JINGYING converts a jewelry picture into a physical prototype, the technologies involved, and the benefits of using CAD/3D prototyping for silver jewelry production.

1. Understanding the Client’s Design Requirements

1.1 Consulta inicial

  • Envio de projeto: Clients provide images (Esboços desenhados à mão, photographs, or digital designs).

  • Material Preference: Prata (925 Prata de lei, Prata fina, or Argentium Silver).

  • Especificações de projeto: Tamanho, grossura, Configurações de pedra preciosa, gravuras, and finishing preferences.

1.2 Feasibility Analysis

  • Avaliação Técnica: Ensuring the design is manufacturable (Por exemplo, integridade estrutural, Undercuts).

  • Estimativa de custos: Based on complexity, material, e trabalho.

2. CAD Modeling Process

2.1 Image Processing & Digital Sketching

  • 2D to 3D Conversion: Using software like Adobe Illustrator or Rhino to outline the design.

  • Vectorization: Converting hand-drawn sketches into editable digital formats.

2.2 3D Modeling in Jewelry CAD Software

  • Software usado:

    • Matrix Gold (Para designs complexos)

    • Rinogold (for parametric modeling)

    • Zbrush (for organic, sculptural designs)

  • Key Steps:

    1. Base Structure Creation – Extruding shapes from 2D outlines.

    2. Detalhamento – Adding textures, gravuras, e configurações de pedras preciosas.

    3. Boolean Operations – Combining/subtracting geometries for hollow designs.

    4. Sizing Adjustments – Ensuring accurate ring sizes, bracelet diameters, etc..

2.3 Client Review & Revisões

  • 3D Renders: Photorealistic images for approval.

  • Modificações: Ajustes baseados em feedback (Por exemplo, grossura, stone placement).

3. 3D Prototipagem (Prototipagem rápida)

3.1 Choosing the Right 3D Printing Technology

Tecnologia Material Precisão Melhor para
SLA (Estereolitografia) Resin ±0.1mm High-detail rings, pingentes
DMLS (Direct Metal Laser Sintering) Metal Powder ±0,05 mm Functional prototypes
Wax Printing Castable Wax ±0.2mm Fundição de investimento

3.2 Printing Process

  1. File Preparation: Exporting the CAD file as an STL/OBJ format.

  2. Support Structures: Adding temporary supports for overhangs.

  3. Printing: Layer-by-layer fabrication (takes 2–6 hours depending on size).

3.3 Pós-processamento

  • Support Removal: Manual or chemical cleaning.

  • Sanding/Polishing: Smoothing layer lines for a flawless finish.

4. Elenco & Finishing the Silver Jewelry

4.1 Fundição de investimento (If Using Wax Prototypes)

  1. Fabricação de mofo: Coating the wax model in ceramic slurry.

  2. Burnout: Melting the wax to leave a hollow mold.

  3. Fundição de Prata: Pouring molten silver (925) into the mold.

  4. Devesting: Breaking the mold to retrieve the silver piece.

4.2 Direct Metal Printing (If Using DMLS)

  • No mold needed – The prototype is already in metal.

  • Requires polishing & revestimento to achieve a mirror finish.

4.3 Acabamento Final

  • Arquivamento & Lixar – Removing imperfections.

  • Polimento – Using rotary tools with diamond paste.

  • Oxidation/Patina – For antique effects (opcional).

  • Gemstone Setting – If applicable.

5. Controle de qualidade & Entrega

5.1 Inspection Checklist

✔ Dimensional accuracy (compared to CAD)
✔ Surface finish (no pits or cracks)
✔ Gemstone security (if set)
✔ Hallmarking (925 carimbo)

5.2 Embalagem & Envio

  • Anti-Tarnish Packaging – Prevents oxidation.

  • Secure Shipping – Insured courier services.

6. Benefits of Choosing JINGYING for CAD/3D Prototyping

✅ Voltação rápida – 5–7 days for CAD, 3–5 days for prototyping.
✅ Econômico – Eliminates manual carving costs.
✅ High Precision – ±0.1mm accuracy.
✅ Personalização – Easy modifications before final production.
