Looking for your next 3D printing project? diese App is the app for you. 3D printing, also known as additive manufacturing (AM), refers to processes used to create a three-dimensional object in which layers of material are formed under computer control to create an object.  Objects can be of almost any shape or geometry and are produced using digital model data from a 3D model or another electronic data source like STL files.  Swipe through over 600K(!! ) free, downloadable 3D print models and curate your own print list.  From sites like Thingiverse, Cults3D, Yeggi, RepRap Facebook Groups and more.  No matter if you've got a DIY Anet A8 or a high-end Zortrax, this is the app for you.  Thus, unlike material removed from a stock in the conventional machining process, 3D printing builds a three-dimensional object from a computer-aided design (CAD) model or STL file by successively adding material layer by layer.
