Well, the answer always depends on the readers, but every single point presented here should serve as a to-level summary that might help very buyer out there. Let us begin from the very basic component of a printer filament, the diameter. There are two common diameters of 3D printer filaments in the market today, a 1.75 mm and a 3mm. If you will check your printer’s filament diameter, it likely falls in either of these two categories.

If ever you had already purchased your own 3D printer, you ought to know that each extruder (the part in where filament is attached) is designed to work with one diameter only and will not work on others. Frist, check your printer’s filament diameter. This could either be seen the specifications or on the manual provided. If still in vain to locate the diameter, surf online and ask questions to forums and user groups.


If you still unable to find the filament’s diameter, look for a measuring device and this will do the trick. Did you know that some printers may use proprietary diameters that are slightly different from the examples above?

A lot of 3D printers were designed with proprietary diameters so to avoid further problems, you have to read up to ensure that your printer can used filaments from supplier other than your printer manufacturer.

But for the sake of education for a 3mm filament, the nominal diameter is at most 3mm (2.88mm) while the nominal diameter of a 1.75 mm is at least 1.75 mm (1.8mm). It is also important to check for lumps and neck-downs because this can cause stripping and jamming.

Your 3D printer is likely be made of ABS or a PLA. Each have its own characteristics so it depends on you which would you prefer. A quick reference table is posted below with each point of distinctive characterization, and the discussion of each detail is found later in this post.
