What is 3D printing?

3D printing is a process used to make three-dimensional objects. Additive processes are used in a way where successive layers of material are laid down under computer control. Objects can be just about any shape or size, and are referenced from a 3D model. 3D models can be created using CAD (computer aided drawing) software or using a 3D scanner. The 3D object is then converted to a STL or OBJ file which is read by the 3D printer to be able to print it. 

The first company to emerge into the consumer 3D printing market was a company called MakerBot. They focused on ready to use out of the box consumer in home 3D printers. 

Since consumer 3D printers have become readily available, the 3D printing community has developed millions of free designs for consumers to print.
