TYPES According to the technology that we used to build

the piece, we can define three types of 3D printers:

PHOTOPOLYMERIZATION The printer illuminates

a liquid by a light or laser.

This, when it’s illuminated, solidifies. He repeat the process layer by layer, until you have finished the process.

SLS OR LASER

These are the printers that are use  in industry. The raw material is in powder form, in a "pool", and a laser is used to melt and solidify the piece.

EXTRUSION

Most 3D printers are of this type. It starts from plastic filament that is heated to melt and layer by layer is deposited.

• The advantage is the low cost of the machine, the material and it is easy to use.
