3D QRコードの作り方
- QRタイプを選択： Select Text/URL, WiFi, or vCard and fill in the content.
- スタイルを選択： Browse 23 module styles in the Styles tab — from classic squares to dots and stars.
- カスタマイズ： Adjust size, depth, base thickness, and colors. Choose a base shape (square, circle, or hex).
- ロゴ追加（任意）： Upload your logo in the Logo tab. Use High error correction for best results.
- エクスポート： Download as STL for 3D printing, OBJ for modeling, or 3MF for multi-color printing.
QRコード3D印刷のベストプラクティス
For the best scan results, use a 最小サイズ50mm with at least 2mm押し出し深さ. Print with high contrast colors — dark modules on a light base or vice versa. 0.2mmレイヤー高さ gives the cleanest edges.
For デュアルカラー印刷, 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.
サポートされるQRコンテンツタイプ
Beyond simple URLs, this tool generates WiFi QRコード (SSID, password, encryption type) that let people connect to your network with a single scan, and vCard QRコード (name, phone, email, company, website) for sharing contact information. All content types produce fully scannable 3D QR codes.
QRコードエラー訂正レベル
QR codes use リードソロモンエラー訂正 to remain scannable even when partially damaged or obscured. Vextrude supports all four levels: 低(7%) for maximum data density, 中(15%) as the default balance, 四分位(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.
ベース形状 & 3Dジオメトリ
Choose from three base shapes: 四角形 (standard, best for framing and mounting), 丸型 (soft corners, modern aesthetic), and 円形 (perfect for coasters, keychains, and badges). Each shape generates watertight 3D geometry with configurable モジュール深さ, ベース厚, and an optional 隆起フレーム for structural rigidity. The no-base option outputs only the QR modules for embedding into your own designs.
人気の使用例
3D印刷QRコード 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.
