ABS, Acrylonitrile Butadiene Styrene, is a commonly used therms plastic in industrial. It is made from petroleum and easy to get, low cost and good mechanical properties make this material widely used in industrial application, such as Lego brick, it is also made of ABS material.
As 3d printing material, ABS filament has many advantages, It has high heat resistance and the glass transition temperature is about 100 ℃, it means this material could bear high temperature before it begin to soft. Due to this feature, ABS part can be used in high temperature atmosphere. ABS is also high durability material, it has great performance in keep aging and chemical resistance.
Setting with 3D Printer
Printer temperature: 230-250 °C
Heated bed: 80-100 °C
Cooling fan: off
Tips for print with ABS filament
- Minimize Warping
Wrap is the most common issue in printing. ABS is a type of thermoplastic, it will shrink if temperature cool down. When abs filament is extruded from the nozzle, the surrounding temperature is much lower than nozzle. The first layer will trend to wrap and will separate from printer plate, this will ruin the print. In order to avoid this problem, we need to use heated bed to improve adhesive. The temperature could be 70-90 degree. Enclosure is also needed for ABS filament, this could keep the surrounding temperature be same, reduce the wrap.
- Using brim and rafts
As we said the below, abs filament is heavy warping in printing. When print with big diameter model, heated bed and enclosure can not assure there will be no warping in print. Before print the first layer, brim and raft could help with the bottom plate bonding. The only problem is that brim and raft is very hard to remove.
- Drying abs filament in oven
ABS filament is hygroscopic, it can absorb the water in humid surroundings. When print with Non-drying abs filament, filament together with water are heated in hot end, there will be bubbles in nozzle. This will reduce the layer adhesive and make abs filament cracking between layer.
- Print in room has good ventilation
ABS filament produces a strong odor when printed. And the amount of toxic substances released during the printing process is much higher than that of PLA. Therefore, you need ventilation room to print ABS filament.
