PLA and ABS are the two most common filament materials for desktop 3D printing. Both materials are thermoplastics, which means they can be heated and extruded through a nozzle, so as to build (3D print) a part layer by layer. PLA (Polylactic Acid) is a thermoplastic that is biodegradable and bioactive, derived from renewable resources such as corn starch and sugar cane. Outside of 3D printing
The ABS pumps the brakes multiple times in an emergency, faster than a track-proven racecar driver’s ability, causing a pulsing sensation that may appear alarming, but it is entirely normal. When ABS is enabled, you are not required to be concerned; it is simply a sign that your vehicle is in good working order.
