PLA is one of the most basic, and simplest, printing filaments. Manufacturers are creating different blends of this plastic to get a better finish, fade layer lines and try to make PLA as durable as ABS. PLA is an ideal filament for beginners. It is suitable for both pens and printers. For a pen, it is most convenient to cut off a piece so that it does not tangle when used by a child or simply for convenience of use.
