Filament (FDM) 

3D printing of FDM technology is the most widespread in the market

The FDM technology (Fused Deposition Modeling), also known as FFF (Fused Filament Manufacturer), is the most widespread on the market today. This technology consists, to explain it in a very simplified way, in the conduction of a plastic filament through an extruder that melts it above its melting temperature and deposits it layer by layer on the base of the XY printer, increasing in height the piece as the Z axis moves. There are two types of filament diameters (1.75 mm and 2.85 mm), and the great advantage of this technology is the wide variety of materials currently developed.

What aspects to take into account when choosing a 3D printer

When choosing which 3D printer to buy, several factors must be considered:

First of all, the type of user that will use the 3D printer, since it is not the same as a particular user, where you can invest more time in carrying out more maintenance or adaptations in the printer, such as an industrial one where, above everything, the robustness and reliability prevail.

On the other hand, it must be taken into account which materials are to be printed and the maximum dimensions required, since this is going to be one of the limiting factors when determining whether the desired 3D printer meets the requirement or not.

And, finally, we must also consider the maximum precision that is being sought, in order to check which 3D printers meet the requirements requested.
