What is 3D printing?
3D printing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
To print an object, you will need to make or download a virtual design of the object. This virtual design is, when printing at the library, an .stl (STereoLithography) or .obj (object) file.
Many people have shared their creations for free online. You can download open-source 3d files on websites like Thingiverse.
You can request a 3D print from one of the library's printers. It will cost 10¢ for every gram of filament used.
