There is a very good chance that you’ve ever seen a 3D printer at a trade show or your school, it was an FDM printer. The FDM printer is the most common type of 3D printer currently available, coming in a host of makes and configurations.
Fused deposition modeling (FDM) is a 3D printing process where thermoplastic filament or feedstock is heated to the required temperature and incrementally laid in a specified pattern. The technology makes use of gantry mounted belt/chain drives to move the extrusion head along the X and Y axis, and then either the extruder head is elevated or the build plate is moved downwards in order to allow layered deposition along the Z axis to effect completion of the 3 dimensional object. Subsequent layers of thermoplastic material fuse fuse together as they are deposited ultimately forming the desired shape.
Sounds simple, right?
It can be. And it can certainly be very entertaining and rewarding watching as an object of your creation comes – literally – to life. However there are a great many details about the type of material, design and settings that should also be considered when FDM printing.
WHY SHOULD I USE FDM PRINTING?
- FDM printing is the most common type of 3D printing currently available.
- Because they are so common, they are also the most affordable type of 3D printer – ranging from less than $500 upwards.
- The popularity of FDM printing means there are a large number of support forums.
- FDM printing offers the broadest range of filament materials – ranging from entry level PLA to PEEK.
…AND THE DRAWBACKS?
- FDM printing is slower than other forms of additive
- Though generally FDM layer resolution is good, it is not as good as resin printing (for example) or selective laser sintering
