### Material Info

#### About
ASA (Acrylonitrile Styrene Acrylate) is a robust and weather-resistant thermoplastic, making it an ideal choice for various outdoor applications. Renowned for its durability and stability, ASA is engineered to withstand harsh weather and maintain its integrity over time. A wide variety of colors is available and can be printed at request through [our Sales team.](/content/business/additive-manufacturing#contactsales/index.html)

Parts are oriented by our team to balance strength, surface finish, and minimal supports. Final orientation is chosen for the best overall result.
