3D printing | How does it work.

3D FDM printing

Cos'è e come funziona la tecnologia di Stampa 3D FDM.

The most widespread 3D printing technology, works with FDM technology, today renamed FFF (Fused Filament Fabrication), melting and extruding a plastic filament, through a thin nozzle called a “nozzle”.

This specific technology of 3D printing so-called “by extrusion of plastic material”, it is the same one that we mainly use in ours 3D FDM printers .

In particular, it was developed by the open source community only starting from 2010, or when the patent of the relevant owner had already expired.

Consequently, the FDM system is currently one of the most widespread and also the cheapest way to print rigid and flexible plastic objects in three dimensions.

FDM technology 3D printers extrude a molten plastic filament between 180 and 300 °C.

FDM 3D Printing Technology

The FDM 3D printer is used to compose a three-dimensional object by superimposing different layers of plastic material which together represent the volume of the object to be manufactured.

The materials that can be used for FDM 3D printing, there are many and always in constant evolution, in fact you can have various plastics available, even particularly ecological ones such as PLA (polylactic acid).

It is a non-toxic and biodegradable polymer of vegetable origin, which allows you to easily produce finished objects, good looking and large.

The Density of Materials for 3D Printing

La densità dei materiali usati nella stampa 3d

Generally in FDM 3D printing different types of plastic materials can be used shaped in the form of real filaments suitable for FDM 3D printers.

Clearly the density of these plastics influences together with the type of polymer used, both the appearance and the physical and mechanical characteristics of the object that will be printed.
