Define filament for 3D printer?

Question

3D printers

Tell me, what is the name of this type of filament (thread) for a 3D printer? I know they have specific names like marble or wood. In general, in addition to black, 3 more colors are needed with inclusions of such white dots, namely dark blue, orange and red. If possible, drop links to the products you need from Aliexpress.
