What is ASA? The Durable Material Behind Our 3D Printed Products

If you've browsed some of our 3D printed products, you may have noticed the material listed as ASA. If you’re wondering what that means and why we use it, here’s a quick breakdown.

ASA Explained

ASA (Acrylonitrile Styrene Acrylate) is a high-performance thermoplastic used in manufacturing and advanced 3D printing. It was originally developed for outdoor applications where durability and weather resistance matter.

In simple terms: ASA is tough, stable, and built to last.

Why We Use ASA

Not all plastics are created equal. Many common 3D printing materials can become brittle, warp, or degrade when exposed to sunlight or heat. ASA is different.

Here’s what makes it stand out:

UV Resistant
ASA holds up extremely well in sunlight. Unlike many plastics, it won’t easily yellow, fade, or weaken after exposure to UV rays.

Weather Resistant
Rain, heat, and cold won’t easily break down ASA, making it ideal for items that may see outdoor use.

Impact Resistant
ASA is tougher than many standard 3D printing materials, meaning it handles drops, bumps, and everyday use better.

Temperature Stable
It performs well in higher temperatures compared to common materials like PLA.

ASA vs Common 3D Printing Materials

Many entry-level 3D printed items are made from PLA because it's easy to print. While PLA works for display pieces, it can soften in heat and degrade faster.

ASA, on the other hand, is designed for real-world use.

That’s why we choose ASA when durability matters.

Built for Real Use

When we make a product from ASA, it means we want it to handle everyday life — not just look good on a shelf. Whether it’s something you carry daily or gear you rely on, ASA helps ensure it stays strong and reliable.

Quality Materials Matter

At the end of the day, materials make a difference. Using high-quality filaments like ASA allows us to create products that last longer and perform better.

When you see ASA listed in one of our product descriptions, you can expect a material that was chosen for strength, durability, and long-term reliability.
