In the last article, we discussed different types of 3D printing technologies that worked tremendously towards making the production and operations of every possible industry pretty easy. Today, here we’ll discuss in detail about the most commonly used and one of the cheapest 3D printing processes, the Fused Deposition Modeling (FDM).

It is an additive manufacturing process developed in the 1980s by Scott Crump, belonging to the material extrusion family. It is the most widely used 3D printing technology representing the largest installed base of 3D printers globally. 

Process:

Let’s understand that how the FDM 3D printing process works:

1. Firstly the CAD file is sliced into multiple layers using a software which enables the 3D printer to read the layers.
2. The filament is then loaded into the printer and fed through the nozzle in the extrusion head. The nozzle is heated to the desired temperature where a motor pushes the filament. The printer then moves the extrusion head along with specified coordinates, laying down the molten material onto the build plate where it cools down and solidifies. The printer moves down as the printer lays another layer, the process is continued until the complete object is created. This printing method might require external support that dissolves after the printing is completed.
3. For the post-production, the object is then given a finishing touch using various methods like sanding, polishing, priming, painting, cold welding, vapor smoothing, epoxy coating, and metal plating.

FDM Materials:

One of the best parts about FDM 3D process is that it allows you to choose from a wide range of materials, starting from commodity thermoplastics (such as PLA, ABS) to engineering plastics (such as PA, TPU, and PETG) and high-performance thermoplastics (such as PEEK, PEI)

You need to remember to carefully choose the material as it will not only affect the mechanical properties and accuracy of the printed product, but also its cost. It is widely used in industries like mechanical engineering and part manufacturers use this technology. For example, brands like BMW and Nestle use FDM technology.

All you need to do is find and identify the right 3D technology for your product and evolve the way you manufacture. You can find the best industry standard 3D printers to meet all your requirements here.
