Acrylonitrile Butadiene Styrene [ABS]
Acrylonitrile Butadiene Styrene [ABS] was the most popular material used to print the first 3D models few years ago and it is extremely popular now as well.
This material is very durable, slightly flexible lightweight and can be easily extruded, which makes it perfect for 3D printing.
It requires less force to extrude then when using PLA, which is another popular 3D filament. This fact makes extrusion easier for small parts.
The disadvantage of ABS is that it requires higher temperature than for example PLA material.
Its glass transition temperature is about 105C and tempertaure about 210° – 250° C is usually used for printing with ABS materials.
Also another drawback of this material is quite intense fumes during printing that can be dangerous for pets or people breathing difficulties. So 3D printers need to be placed in well ventilated area. Also good advice is to avoid breathing in fumes during printing Considering the cost of 3D materials ABS is the cheapest, which makes it favourite in printing communities until now.
