3D Printable Chinese Dragon Head Coin – Technical & Design Guide

1. Core Specifications-Diameter: 26.5 mm (standard large coin size)-Thickness: 3.12 mm (optimal for high-detail 3D printing)
2. Weight Simulation (Post-Casting):

Yellow Gold (18K–22K): 20.58g (if cast in metal)

Silver Base Layer: 13.91g (if bimetallic design)

• Recommended 3D Printing Material:

Prototyping: Resin (e.g., Siraya Tech Smoky Black) for ultra-fine detail

Metal Casting Ready: Wax/resin hybrid for lost-wax investment casting

1. Design Highlights (Optimized for 3D Printing)A. Dragon Head SculptureHyper-Detailed 3D Model:

High-Poly Mesh (500k+ polygons for scales, teeth, whiskers)

Undercuts & Overhangs supported for SLS/DLP printing

Key Features:

Realistic Scales: Parametric design for depth (0.1–0.3mm ridges)

Dynamic Expression: Open jaws, flared nostrils, and gemstone sockets (optional)

Mane & Horns: Flowing, organic curves (avoiding fragile thin sections)

B. Structural Integrity for PrintingWall Thickness: ≥1.0mm (prevents breakage during printing/post-processing)

Support-Free Design: 45° rule for FDM-friendly versions

Textured Background:

Clouds/Flames: 0.2–0.5mm recessed for contrast

Chinese Characters: Embossed (≥0.5mm height for legibility)
