With the accuracy and repeatability of any 3D printing technology, FDM technology uses especially designed 3D printers and production-grade thermoplastics in building durable, strong, and dimensionally stable parts.

When to use FDM?
Globally, FDM is preferred by most companies as their 3D Printing technology. It is usually the first 3D printing technology that is introduced to people. It is very well-known in the 3D printing industry that the largest inventory of 3D printers base is consist of FDM.
Pros of FDM
If you choose FDM, you don't need to worry about scalability as it is one of the biggest advantages of this technology. The only reason that you will encounter problems in changing the size of the build area is the movement of each gantry. Material flexibility is another advantage that FDM is known for. Printing exotic filaments and a wide variety of thermoplastic materials even with few customization and upgrades will be an easy task if using any FDM printer.
Cons of FDM
One of the most talked about disadvantages of FDM 3D printing is part quality or detail. The material undergoes extrusion in layers causing it to have predefined thickness. Thus, printing high detail prints often requires numerous post-processing just to achieve high quality and professional-looking finish.
FDM was conceptualized by scientist David E.H. Jones. It was introduced to the public in 1974, making it the oldest and therefore most popular 3D printing technology. True to this day, the largest number of 3D printers utilizes it.
