What is 3D printing and how it works.
Find out what 3D printing is and how it works. FDM technology and its applications, From rapid prototyping to industrial production.
La Stampa 3D, or additive production, It is a revolutionary technology that allows you to create physical objects starting from digital models. It works by stratifying materials like plastic, metal or resin and unlike traditional methods (like milling), 3D printing reduces waste, times and costs, opening infinite possibilities in sectors such as medicine, aerospace and design.
In this article we describe how the most common 3D printing technology called called: FFF-FDM, which consists in melting and at the same time extruded through a thin nozzle called "Nozzle", a filament in plastic material, Generally having a diameter of 1.75 mm.
3D printing technology FDM, It was developed by the Open Source Community only since 2010, that is, when the patent of the relative owner had already expired.
The FDM system is therefore currently one of the most widespread and also the most economical way to print rigid and flexible plastic objects in three dimensions.
FDM 3D printers extrude molten plastic filament at between 180 and 300 °C.
The FDM 3D printer is used to compose a three-dimensional object by overlapping several 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, are many and always evolving, in fact you can have different plastics, even particularly ecological ones such as PLA (polylactic acid).
It is a non-toxic and biodegradable polymer of plant origin, which allows you to easily produce finished objects, Good looking and large.
The Density of Materials for 3D Printing
Generally, different types of plastic materials can be used in FDM 3D Printing, 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.
