This Kitronik University course explains the differences between various types of extrusion style 3D printer filament.
What is Extrusion Style 3D Printer Filament:
A 3D printer behaves like a 2D printer in the same way that you instruct the 2D printer to print a 2D drawing on paper. You use word processing software and the printer replicates the writing by 'printing' out a pattern as instructed by the software using liquid ink. Laser printers use a laser to etch the toner onto the page, so that is still a process of 2D printing. Instead, the 3D printer 'prints' a 3D object in successive layers using the 'filament' from a design drawn in CAD software. The Robox 3D Printer is an excellent example of a 3D printer with dual nozzles that can accept different types of plastic.
