Numakers ASA

Description

Numakers ASA (Acrylonitrile Styrene Acrylate) is designed for professional and outdoor 3D printing applications. It combines exceptional UV resistance, high durability, and smooth matte finish, making it a top choice for projects exposed to sunlight and harsh environments.

Compared to standard ABS, ASA offers better weather resistance, less yellowing, and improved surface quality, while remaining acetone-soluble for easy post-processing or gluing.

Key Advantages:

• Excellent UV and weather resistance
• Durable, impact- and wear-resistant
• Matte surface finish and easy post-processing
• Soluble in acetone (great for bonding and smoothing)
• Suitable for high-stress or outdoor parts

Limitations:

• Requires higher printing temperature
• Can warp without enclosure
• Slight odor during printing (less than ABS)
• Hygroscopic — keep filament dry

Applications: Outdoor Signage • Functional Prototypes • Automotive Parts • Mechanical Components • Enclosures
