Superior surface finish and long-term environmental stability
Figure 4 TOUGH-BLK 20 is a strong black plastic simulating injection-molded ABS, with long-term environmental stability for fast high-performance prototyping and production applications where lifecycle stability is critical and mechanical properties fit. With production-grade indoor and outdoor environmental stability, mechanical properties, color, opacity, dimensions will not change over time with exposure to daylight. This material provides high precision, smooth surface finish and exceptional sidewall quality with minimal finishing.

The full suite of mechanical properties are given per ASTM and ISO standards where applicable. All parts are conditioned per ASTM recommended standards for a minimum of 40 hours at 23 °C, 50% RH. Material properties include physical and mechanical properties, as well as thermal.
Figure 4 technology prints parts that are isotropic in mechanical properties meaning the parts printed along either the XYZ axis will give similar results. Parts do not need to be oriented to get the highest mechanical properties, further improving the degree of freedom for part orientation for mechanical properties.
