About Your Download

3D Builder is Microsoft's free 3D modeling app for Windows 10 and 11. It opens STL, OBJ, PLY and 3MF files, repairs broken meshes automatically and exports a print-ready model. The download is the original 2015.209.2327.4143 app package (about 127 MB), the same build that used to ship in the Microsoft Store.
