ASAfused deposition modeling
ASA (Acrylonitrile Styrene Acrylate) material is a thermoplastic known for its strong resistance to ultraviolet (UV) light, weather, and environmental conditions, making it ideal for outdoor applications. ASA possesses similar mechanical and thermal properties to ABS, but with enhanced UV stability. It's often chosen for its aesthetics, as it retains color and gloss over time in outdoor exposure. This material is widely used in automotive, sporting goods, and outdoor functional testing.

ASA (Acrylic Styrene Acrylonitrile) is a commonly used thermoplastic similar to ABS, but offers superior UV resistance, mechanical properties and aesthetics. ASA is ideal for outdoor applications and is frequently used in automotive and marine industries where parts are exposed to adverse weather conditions. ASA is highly resistant to UV rays and not susceptible to yellowing or degrading over time from exposure.
Forge Labs uses ASA by Stratasys which offers a wide variety of colour options and improved aesthetics over ABS plastic. Parts are produced on the Stratasys Fortus series printers, offering excellent tolerances, finish and repeatability.
ASA offers excellent mechanical properties, including high tensile strength, stiffness, and good impact resistance. It's more rigid compared to ABS, providing better resistance to warping, making it suitable for demanding applications. Its durability under physical stress makes it ideal for outdoor and industrial components that must withstand mechanical loads, impacts, or constant use.
ASA material exhibits strong resistance to various chemicals, including oils, salts, and most acids and bases. This chemical resistance makes it a preferred choice in environments exposed to harsh chemicals, such as industrial settings. However, it can be sensitive to certain solvents and chemicals, which may cause degradation or affect its mechanical properties. It's commonly used for parts that require long-term exposure to chemicals without significant deterioration.
ASA has a higher thermal resistance compared to many other thermoplastics, including ABS. It can withstand temperatures slightly higher than ABS, maintaining its form and function in environments up to 95-100°C. This makes it suitable for outdoor applications or under the hood automotive components, where heat resistance is crucial. Its UV resistance also contributes to its thermal stability, especially in outdoor applications.
ASA is widely used in automotive parts, outdoor equipment, and functional prototypes exposed to harsh environmental conditions. Its UV stability, weather resistance, and robust mechanical properties make it ideal for outdoor fixtures, garden equipment, and automotive exteriors. ASA’s ability to maintain color and physical properties over time under sun exposure is particularly valued in applications where aesthetic appearance and long-term durability are essential.
