ABS or Polycarbonate: Choosing the Right Material for Your Project
Learn the differences between ABS and Polycarbonate, and find out which material performs better for your 3D printing projects or industrial applications.
Introduction
ABS (Acrylonitrile Butadiene Styrene) and Polycarbonate are two popular plastics used in 3D printing and various manufacturing processes. Both materials have unique properties that make them suitable for different applications.
In this blog, we will explore the characteristics of ABS and Polycarbonate, compare their strengths and weaknesses, and help you decide which material is best suited for your specific needs.
What Is ABS?
ABS, short for Acrylonitrile Butadiene Styrene, is a strong and lightweight plastic that is commonly used in 3D printing. It is known for its good impact resistance and toughness, which makes it a popular choice for items that need to be sturdy, such as toys, automotive parts, and household goods.
Key Properties: ABS is durable and resistant to physical impacts, making it ideal for functional parts. It has moderate heat resistance, allowing it to withstand temperatures that are not extremely high but still sufficient for everyday use. However, ABS has a tendency to warp during the printing process, which requires careful handling.
Common Uses: ABS is often used in making prototypes, protective cases, and other parts that need to be strong but not excessively rigid. It is also commonly used to make Lego bricks, as it offers a good balance of toughness and flexibility.

What Is Polycarbonate?
Polycarbonate, also known as PC, is a tough and transparent plastic that is widely recognized for its strength and flexibility. It is highly impact-resistant and is used in products where toughness is key, such as safety goggles, bulletproof windows, and durable 3D-printed parts.
Key Properties: Polycarbonate is known for its excellent impact strength and high-temperature resistance. Unlike ABS, it can tolerate higher temperatures without losing its properties. It is also slightly flexible, which makes it less likely to crack under pressure. However, Polycarbonate is more challenging to print with because it requires higher temperatures and careful handling to avoid warping or cracking.
Common Uses: Polycarbonate is used in applications that demand durability, such as protective gear, automotive components, and even optical discs like CDs and DVDs. It is a preferred material for parts that need to be clear and extremely tough, making it suitable for safety equipment.

ABS vs Polycarbonate: Head-to-Head Comparison
Property | ABS | Polycarbonate |
|---|---|---|
Strength and Durability | Tough but less strong, suitable for lighter-duty applications | Stronger and highly impact-resistant, suitable for heavy-duty applications |
Heat Resistance | Moderate, can soften under high heat | High, maintains properties at higher temperatures |
Chemical Resistance | Moderate | Good, resists exposure to various chemicals |
Ease of Use in 3D Printing | Easier to print, lower temperatures, may warp | Challenging to print, requires high temperatures and precise control |
Cost | Cheaper, cost-effective for many projects | More expensive due to superior properties |
Visual Properties | Smooth, matte finish, easily colored | Naturally transparent, glossy, can be colored |
Which Material Should You Choose?
The choice between ABS and Polycarbonate depends on the specific requirements of your project. If you need a material that is strong, cost-effective, and relatively easy to work with, ABS is a great choice. It is suitable for prototypes, household items, and parts that do not need to withstand extremely high temperatures or heavy impacts.
On the other hand, if your project demands high impact resistance, clarity, and the ability to withstand higher temperatures, Polycarbonate is the better option. It is ideal for safety equipment, durable parts, and applications where toughness is critical.
Consider the properties of both materials and weigh them against your project's requirements to make an informed decision.
Conclusion
ABS and Polycarbonate are both versatile materials used in 3D printing and manufacturing, each with its own advantages and limitations. ABS is affordable, easy to print, and provides good strength for most applications. Polycarbonate offers superior impact resistance, heat resistance, and clarity, but at a higher cost and with more challenging printing requirements.

FAQs
Q1: Is Polycarbonate stronger than ABS?
Yes, Polycarbonate is generally stronger and more impact-resistant compared to ABS. It can handle higher levels of stress and force without breaking, making it suitable for heavy-duty applications.
Q2: Which material is easier to print with, ABS or Polycarbonate?
ABS is easier to print with because it requires lower temperatures and is less challenging to manage during the printing process. Polycarbonate requires higher temperatures and careful handling to avoid warping or cracking.
Q3: Which material is more heat resistant?
Polycarbonate has better heat resistance than ABS and can maintain its properties at higher temperatures. ABS can soften under high heat, which makes it less suitable for applications involving elevated temperatures.
Q4: Is ABS cheaper than Polycarbonate?
Yes, ABS is generally cheaper than Polycarbonate, making it a cost-effective option for many projects, especially when high impact resistance and heat resistance are not critical requirements.
Q5: Can Polycarbonate be used for clear parts?
Yes, Polycarbonate is naturally transparent and can be used for clear parts. It is valued for its clarity and is commonly used in safety goggles, optical discs, and other applications requiring transparency.
Q6: Which material should I choose for outdoor applications?
Polycarbonate is typically a better choice for outdoor applications due to its superior impact resistance and heat resistance. ABS may degrade under prolonged exposure to sunlight and high temperatures.
