Adobe is adding new tools to Photoshop that let users create and edit designs for 3D printing. Before 3D printers crank out objects, a user needs digital model, either one they create or download from the Internet. One you’ve got one, though, you’ll need software that supports 3D imagery if you want to edit it. As of today, Photoshop users can design, edit and customize those 3D models similar to how you might adjust a 2D picture within the app.
