3D Builder 2015.209.2327.4143

3D Builder is a free Microsoft app for Windows that lets you view, create, edit, repair and print 3D models. You can build scenes from premade objects, import models, scale and position parts, apply textures and colors, and prepare models for 3D printing.

3D Builder supports common formats including 3MF, STL, OBJ and PLY. It can also open some additional model and mesh formats; use Export/Save to output to standard 3D-printable formats such as 3MF and STL.

Yes. 3D Builder includes automatic model repair tools to fix common mesh problems (holes, inverted normals, non-manifold edges) and make models watertight for 3D printing. You can run automatic repairs or use manual editing tools to adjust geometry.

3D Builder can send models to compatible 3D printers and to Windows’ 3D Print services. It supports printers that have Windows print drivers or integrate with the Windows 3D Printing framework. You can also export a printable file (STL/3MF) and use a third-party slicer or online 3D printing service.

Use the Paint tool to apply colors, textures and decals to your model. You can pick solid colors, gradients, or image-based textures. Painted results are visible in the app and can be preserved when exporting formats that support color (such as 3MF and some OBJ configurations).

3D Builder runs on Windows 10 and later (including Windows 11) as a Microsoft Store app. Ensure your PC meets basic Windows app requirements and has a GPU/driver capable of rendering 3D content. The app is updated through the Microsoft Store.

Yes — 3D Builder is free. Install or reinstall it by searching for “3D Builder” in the Microsoft Store (or visit its Microsoft Store page) and selecting Install. If it came preinstalled, you can also reset or repair it from Windows Settings > Apps if needed.

You can import scan files (STL, OBJ, PLY, etc.) into 3D Builder to edit and repair them. While 3D Builder itself does not perform photogrammetry, you can use other scanning apps to create model files and then refine them in 3D Builder.

Use Save or Save As to store projects locally or into folders you choose. Export or Save As to 3D-printable formats (STL, 3MF, OBJ) to share with others or upload to printing services. You can also capture screenshots of the viewport for sharing images.

For help, consult the Microsoft Store product page, built-in app help sections, or Microsoft support articles. For advanced editing and features not available in 3D Builder, consider using dedicated 3D modeling tools (Blender, Meshmixer, Fusion 360) alongside 3D Builder for printing preparation.
