Fused deposition modeling also known as fused filament fabrication or FFF is an additive manufacturing process where the concept of material extrusion is followed.
Here the layers of products are extruded at their pre-determined age. The material used in them is thermoplastic and comes in filament form. Meanwhile, the fdm 3d printer play a huge role without which the development of the products wouldn’t be even possible.
The role of FDM 3D printers
When it comes to saving time the FDM 3D printers play a huge role. You can easily sketch the product can test it on the same day; it increases your understandability of the production of numerous items.
Even in the economy, they have played the role of heroes in saving our lives. All the machines that you see in hospitals whether an ECG machine or anX-ray machine are built with the help of fused deposition modeling.
The 3-dimensional modeling, on the other hand, is studied on the computer where you get a better idea of which part of the machine is supposed to be eliminated and which part should be kept. This way we save a lot of material too.
Working on FDM 3D printing
The material is extruded layer by layer at a controlled temperature.
Thermoplastic polymer material suckles into the temperature-controlled FDM and is heated in the sem-liquid form.
The material afterward solidifies, then the overhanging geometries are designed which eliminate the excessive parts of the object.
