3D Printing

FDM is Fused Deposition Modeling. AS the name suggests material will be deposited on layers at melting temperatures so that it can fuse with the previous layer of the material. This type of manufacturing is known as Additive Manufacturing(AM). FDM constructs a part by precisely moving the extruder nozzle in predetermined motion. Materials used in this manufacturing method are called Thermoplastic polymers.

This technology was first developed by Stratasys founder Scott Crump in 1989. It is unbelievable that this technology was around for multiple decades but has only made it to mainstream manufacturing since the last 5-7 years.

How Does It Work


FDM 3D printer works by depositing melted filament material over a build platform layer by layer until you have a completed part. FDM uses digital design files that are uploaded to the machine itself and translates them into physical dimensions. Materials for FDM include polymers such as ABS, PLA, PETG and PEI, which the machine feeds as threads through a heated nozzle.


To operate an FDM machine, you first load a spool of this thermoplastic filament into the printer. Once the nozzle hits the desired temperature, the printer feeds the filament through an extrusion head and nozzle.


This extrusion head is attached to a three-axis system that allows it to move across the X, Y and Z axes. The printer extrudes melted material in thin strands and deposits them layer by layer along a path determined by the design. Once deposited, the material cools and solidifies. You can attach fans to the extrusion head to accelerate cooling in some cases.


To fill an area, multiple passes are required, similar to coloring in a shape. with a marker. When the printer finishes a layer, the build platform descends and the machine begins work on the next layer. In some machine setups, the extrusion head moves up. This process repeats until the part is finished.
