Microsoft made a big deal of building 3D printer support into Windows 8.1, and today it's releasing a tool that lets even newcomers create objects of their own. The new 3D Builder app includes a catalog of pre-designed items that virtually anyone can start printing right away. Especially curious users can adjust and combine objects without having to be a CAD expert, and those with access to more advanced tools can import their masterpieces. As long as you've already shelled out for the requisite printer, you can try 3D Builder for yourself at the source link.
