ABS can be said to be the most commonly used printing material for FDM. Currently, it is available in a variety of colors. It is the favorite printing material for consumer 3D printer users, such as printing toys and creative home accessories. ABS materials are usually in the form of filaments that are heated and melted through a 3D printing nozzle. Since the nozzle needs to be solidified immediately after the nozzle is ejected, the temperature of the nozzle heating is controlled to be 1 ° C to 2 ° C higher than the thermal melting point of the ABS material. Different ABSs are not compatible with the nozzles whose temperature cannot be adjusted due to the different melting points. This is why it is best to buy printed materials from the original manufacturer.
