Which one should be preferred, 1.75 mm Filament or 3.00 mm Filament? 


Today if you go to any 3D printer filament store, you’ll usually find two options for filament size: 1.75 mm filament and 3.0 mm filament. Many people wonder if there is any difference between these two options. Is there any difference in practice, if so what are they? In this article we try to explain them. 

As you might guess, technically printing with 1.75 mm filament and printing with 3.00 mm filament will not be exactly the same. Let's look at the table below for the differences. 

  1.75 mm Filament 3.00 mm Filament

* For small, intricate and detailed designs finer filaments give better results.

* It requires less torque, means needs less power to melt and push the filament through the nozzle on the extruder head and there is the control advance.

* Printers with 3.00 mm filament print larger parts or devices faster. It is preferred especially in printing rough prototypes or large numbers of simple devices.

* Compared with 3.00 mm filaments, 1.75 mm filaments are slightly more expensive.

* It will take longer time to build larger parts or devices.

* The details will not be as good as finer filaments gets.

* Because of the torque issue 3D printer is working harder to melt the filament and feed it through the nozzle, the process is harder to control. Therefore undesirable roughness is more likely to occur.


As you notice one's advantages are the other one's disadvantages. So again, there is not only one exact right.

Your choice will vary according to your design's complexity, your time pressure and your expectations from the output.
