如何创建3D二维码
- 选择QR类型： Select Text/URL, WiFi, or vCard and fill in the content.
- 选择样式： Browse 23 module styles in the Styles tab — from classic squares to dots and stars.
- 自定义： Adjust size, depth, base thickness, and colors. Choose a base shape (square, circle, or hex).
- 添加Logo（可选）： Upload your logo in the Logo tab. Use High error correction for best results.
- 导出： Download as STL for 3D printing, OBJ for modeling, or 3MF for multi-color printing.
3D打印二维码最佳实践
For the best scan results, use a 最小尺寸50毫米 with at least 2毫米挤出深度. Print with high contrast colors — dark modules on a light base or vice versa. 0.2毫米层高 gives the cleanest edges.
For 双色打印, use the 3MF export which embeds color data, or use the multi-part STL option to import base and QR modules as separate objects in your slicer. You can also pause the print at the base layer height and swap filament for a manual color change.
支持的QR内容类型
Beyond simple URLs, this tool generates WiFi二维码 (SSID, password, encryption type) that let people connect to your network with a single scan, and vCard二维码 (name, phone, email, company, website) for sharing contact information. All content types produce fully scannable 3D QR codes.
二维码纠错级别
QR codes use 里德-所罗门纠错 to remain scannable even when partially damaged or obscured. Vextrude supports all four levels: 低(7%) for maximum data density, 中等(15%) as the default balance, 四分之一(25%) for moderate resilience, and 高(30%) which is required when embedding a logo in the center. Higher error correction increases the QR module count, so choose the lowest level that meets your needs for smaller, cleaner designs.
底座形状 & 3D几何体
Choose from three base shapes: 方形 (standard, best for framing and mounting), 圆角 (soft corners, modern aesthetic), and 圆形 (perfect for coasters, keychains, and badges). Each shape generates watertight 3D geometry with configurable 模块深度, 底座厚度, and an optional 凸起边框 for structural rigidity. The no-base option outputs only the QR modules for embedding into your own designs.
热门使用案例
3D打印二维码 are used for business cards and desk signs, retail product tags, restaurant table numbers with menu links, WiFi access codes for offices and Airbnbs, event badges and conference swag, museum exhibit labels, real estate listing signs, and personalized gifts. The raised 3D surface is more durable than printed stickers, resistant to weather, and adds a premium tactile quality that flat QR codes lack.
