sketch2stl exports standard binary STL files, which are compatible with virtually all 3D printers and slicing software (Cura, PrusaSlicer, BambuStudio, OrcaSlicer, etc.).

After exporting, use the share button to send the file via AirDrop, email, or save it to the Files app. From there, you can transfer it to your computer or directly to your printer's SD card via USB.

No. Everything — drawing, 3D conversion, and STL export — runs entirely on your device. No internet connection is needed at any point.

sketch2stl requires iOS 17.0 or later.

Make sure your drawing has a closed outline around the design. The app needs a boundary to create the 3D base shape. Try drawing with thicker lines and ensure shapes are fully enclosed. You can also adjust parameters like blur radius and minimum area on the Convert tab.

sketch2stl 导出标准二进制 STL 文件，兼容几乎所有 3D 打印机和切片软件（Cura、PrusaSlicer、BambuStudio、OrcaSlicer 等）。

导出后，使用分享按钮通过 AirDrop、邮件发送，或保存到"文件"App。然后可以传到电脑上，或通过 USB 拷贝到打印机的 SD 卡中。

不需要。绘图、3D 转换和 STL 导出全部在你的设备上本地完成，任何时候都不需要联网。

sketch2stl 需要 iOS 17.0 或更高版本。

请确保你的图形有一个封闭的外轮廓。应用需要一个封闭的边界来创建 3D 底座。试着用粗一点的笔画，确保图形完全封闭。你也可以在"转换"页面调整模糊半径和最小面积等参数。
