ABS

ABS (Acrylonitrile Butadiene Styrene) has a long history in the 3D printing world. This material was one of the first plastics to be used with industrial 3D printers. Many years later, ABS is still a very popular material thanks to its low cost and good mechanical properties. ABS is known for its toughness and impact resistance, allowing you to print durable parts that will hold up to extra usage and wear. LEGO building blocks are made from this material for that same reason! ABS also has a higher glass transition temperature, which means the material can withstand much higher temperatures before it begins to deform. This makes ABS a great choice for outdoor or high temperature applications. When printing with ABS, be sure to use an open space with good ventilation, as the material tends to have a slight odor. ABS also tends to contract quite a bit as it cools, so controlling the temperature of your build volume and the part inside can have major benefits.

Pros

  • Low Cost
  • Good impact and wear resistance
  • Less oozing and stringing gives models smoother finish
  • Good heat resistance

Cons

  • Heavy warping
  • Needs heated bed or heated chamber
  • Produces a pungent odor while printing
  • Parts tend to shrink leading to dimensional inaccuracy
