what is FDM?

Some newcomers asking, FDM, what it is? how to use? why I use it?

For these questions, here I concentrated to answer, Of course, here I mainly discuss the desktop level.

Let's talk about the basic principle first:

3D printing using Fused Deposition Modeling (FDM) is the most widely-used method due to the technology being relatively simple, 

user-friendly, and less expensive. 

The production material (such as ABS or PLA or TPU filament) being fed from a pool through a heated printer nozzle. 

Due to the high temperature of the nozzle, the material converts into a semi-liquid state as it is extruded just like the extruding the toothpaste.

 After leaving the nozzle, the material almost immediately hardens and binds to the layer underneath it.

The main reasons for using FDM are cost and time. 

Rather than investing tens of thousands of dollars into an injection tool, you can 3D print the part.

 It's a much faster and lower cost way to move your product idea into production. 

FDM is the most affordable 3D printing technology available today, and has become the technology of choice for 3D printing projects for personal use.
