3D Printer

A **3D printer** is a device (output device) that creates **three-dimensional solid objects** from a digital file by an additive method. In **additive processes**, the object is created by laying down continuous layers of material until the entire project is completed. Each of these layers can be considered to be a narrowly cut horizontal section of a given object.



The object is formed layer by layer by melting a thin strip of plastic material. The material ‒ printing line is gradually melted and sprayed with a nozzle on a heated pad where it is cooled by ambient air and a fan. The displacement of the print string arranges a feed wheel that gets its speed from the cork motor. The ideal temperature of the nozzle and material is provided by a fan with a temperature sensor.
