FDM (Fused Deposition Modeling)
Fused Deposition Modeling, or FDM, is a 3D printing technology widely used in the additive manufacturing industry. In this process, a thermoplastic material is heated and deposited in successive layers, thus forming the desired object. The technique has gained prominence due to its versatility, low cost, and ability to produce complex parts. In this article, we will explore its operating principles, the materials used, its applications in prosthetics and modeling, as well as trends in FDM technology.
Operating Principles
The operating principles of FDM (Fused Deposition Modeling) technology are based on the creation of three-dimensional objects by depositing thermoplastic material in successive layers. This process is performed by a 3D printer that uses a filament material, such as ABS or PLA, which is heated and deposited in a controlled manner to form the desired object.
Successive Layers: FDM technology works by building the object in thin layers, one on top of the other, allowing for the creation of complex parts with precise details. Each layer is fused to the previous layer as the material is deposited, ensuring the integrity and strength of the final object.
Temperature Control: One of the fundamental principles of FDM is precise control of material temperature during the deposition process. This is essential to ensure proper layer adhesion, surface quality, and the object's mechanical strength.
Modeling Software: FDM technology requires the use of 3D modeling software to convert a digital design into instructions that the printer can follow. The software divides the model into layers and generates G-code, which controls the movement of the print head and the extrusion of the material.
