ABS is generally very durable and strong, slightly flexible and quite resistant to heat. 3D printers able to process ABS plastics normally operate with a hot end (the heated part melting the plastic, before it’s forced through the print nozzle) at a temperature around 210-250°C. Therefore, a 3D printer able to process ABS is necessarily equipped with a heated printbed, in order to prevent warping or cracking of the printed materials.
