ABS - 1.75mm

Acrylonitrile Butadiene Styrene (ABS) is a lightweight thermoplastic with better mechanical properties than HDPE and less brittle than PLA.  It handles higher temperatures better for applications such as extruders and X-carriages setups without a fan.  It can also be post-processed with acetone to provide a glossy finish. A heated printing surface is recommended, as ABS plastic will contract when cooled leading to warped parts.
