3D printing explained

3D printing is a process that creates real objects from digital files. Instead of cutting material away, a 3D printer adds material one layer at a time until the object is complete.

This is also called additive manufacturing. It is used for toys, tools, models, replacement parts, prototypes, decorations, cosplay items, and professional parts.
