ABS is the second most used 3D printing material. It is strong, flexible and has a high heat resistance. ABS is a preferred plastic for engineers and professional applications. ABS can be smoothened with acetone. To make a proper 3D print with ABS you will need a heated print bed. Ultrafuse® ABS filament should be stored at 15 - 25°C in its originally sealed package in a clean and dry environment.
