Описание слайда:

A 3D printer is a device for making a three-dimensional object from a 3D model or other electronic data source through additive processes in which successive layers of material ( including plastics, metals, food, cement, wood, and other materials) are laid down under computer control. It is called a printer by analogy with an inkjet printer which produces a two-dimensional document by a similar process of depositing a layer of ink on paper.

Hand-held scanners - they lack the engine, therefore, the object has to scan the user manual, his only advantage is the low cost and mobility, while it has a lot of drawbacks - low resolution, low speed, narrow scanning strip (up to 10 cm.), possible distortions of the image, since the user will be difficult to move the scanner at a constant velocity.
