Scan4+ Support

Which devices are supported?

Scan4+ requires an Apple device equipped with a LiDAR Scanner running iOS 18 or iPadOS 18 or later.

• iPhone: iPhone 12 Pro, 12 Pro Max, 13 Pro, 13 Pro Max, 14 Pro, 14 Pro Max, 15 Pro, 15 Pro Max, 16 Pro, 16 Pro Max, and later Pro models.
• iPad: iPad Pro 11-inch (2nd generation or later) and iPad Pro 12.9-inch (4th generation or later), or iPad Pro with M4.

Non-Pro iPhone models do not have hardware LiDAR and cannot perform guided depth scanning.

How do I get the best scan quality?

Follow these field-tested capture techniques for pristine geometric accuracy:

• Lighting: Use diffuse, indirect lighting. Avoid harsh direct sun, deep shadows, and flickering overhead lights.
• Object Material: Matte, textured surfaces scan best. Shiny chrome, mirrored surfaces, clear glass, and pitch-black plastics lack optical texture—spray them with scanning spray or foot powder if needed.
• 3 Passes Strategy: Orbit the object 3 times at different elevations: once level with the object, once angled down from above (45°), and once angled slightly upward from below.
• Flipping Objects: To capture the bottom, scan the top and sides, pause, carefully flip the object upside down onto a neutral backdrop, and complete the guided pass.

How do I export models for 3D printing?

Open any completed scan in Scan4+ and tap the Export button:

• STL (Recommended for 3D Printing): Exported in exact millimeter scale (1 unit = 1 mm). Load directly into Bambu Studio, PrusaSlicer, OrcaSlicer, or Cura without scaling issues.
• OBJ + MTL ZIP: Contains the 3D mesh along with full color diffuse texture maps, perfect for full-color PolyJet 3D printing or rendering in Blender.

How does public sharing work?

Tap Share on any scan. A secure public link is generated that opens an interactive 3D web viewer on any desktop or mobile browser. On iPhone and iPad, viewers can tap to project the object directly into their physical room in AR Quick Look. You can revoke the share link anytime in the app to disable access.

How do I delete my data or account?

Inside the Scan4+ app, navigate to Settings > Account and tap Delete account. All your account metadata, cloud authentication tokens, and uploaded 3D models will be deleted immediately and permanently from our Cloudflare storage. You can also email zsinba@gmail.com to request manual deletion.

支持哪些苹果设备？

Scan4+ 依托硬件级激光雷达（LiDAR）与深度感知引擎，需要运行 iOS 18 或 iPadOS 18 及更高版本、且搭载激光雷达的 Pro 系列机型：

• iPhone 机型： iPhone 12 Pro / Pro Max、13 Pro / Pro Max、14 Pro / Pro Max、15 Pro / Pro Max、16 Pro / Pro Max 及更新 Pro 机型。
• iPad 机型： iPad Pro 11 英寸（第 2 代及更新）与 iPad Pro 12.9 英寸（第 4 代及更新）、M4 芯片 iPad Pro 系列。

注：标准版及 Plus 版 iPhone 无激光雷达传感器，暂无法运行引导式深度扫描。

如何获得最高精度的扫描效果？

• 柔和光照： 建议在明亮但均匀的散射光线下扫描，避免强烈的阳光直射或局部大面积阴影。
• 材质特征： 哑光、表面有纹理的物体扫描效果最好。对于高光反光、镜面金属、透明玻璃或纯黑吸光物体，建议使用 3D 扫描显影喷雾辅助。
• 三圈环绕取景： 围绕被测物体绕行 3 圈并保持平稳移动：第 1 圈平视居中，第 2 圈从斜上方约 45 度俯视，第 3 圈从斜下方微仰视。
• 翻转扫描底部： 针对需要封底的物体，可在扫描完顶部与侧面后点击暂停，将物体平稳翻转后继续扫描底部，最后交由算法自动拼接。

如何导出用于 3D 打印的文件？

在 App 内打开已完成的扫描详情，轻点导出：

• STL 格式（3D 打印首选）： 模型严格按 1:1 毫米级实际尺寸生成（1 unit = 1 mm），可直接拖入 Bambu Studio、PrusaSlicer、拓竹或创想切片软件中切片打印，无需手动缩放。
• OBJ + MTL 压缩包： 包含网格几何与完整的彩色 UV 贴图，适用于全彩 3D 打印或导入 Blender 进行二次雕刻。

如何将模型分享给他人查看？

轻点任意模型详情中的分享按钮，即可生成专有网页链接。对方无需安装 App，即可在任意浏览器中 360 度交互旋转模型，或在 iPhone/iPad 上一键开启 AR 现实投影。您可随时在 App 内关闭分享，关闭后网页链接立即失效。

如何彻底删除我的数据或注销账号？

在 App 中进入设置 > 账号，轻点注销账号，系统将在 Cloudflare 云端立即抹除您的用户信息及所有已上传模型。您亦可随时发邮件至 zsinba@gmail.com 申请人工注销。
