Fused Deposition Modeling (FDM) uses a heated filament, like ABS or PLA, which is extruded through a nozzle that follows a programmed path to deposit material layer by layer on a build platform. The thermoplastics used in FDM create strong, durable parts that can endure mechanical stress. Its use of standard materials makes it a cost-effective choice for prototyping and low-volume production.

Advantages:

• Impact Resistance: PC-ABS offers the highest impact resistance of any FDM material, making it ideal for applications that need to withstand physical stress and shock.
• Strength and Durability: This material combines the strength and heat resistance of polycarbonate (PC) with the flexibility of ABS, offering a balance of toughness and resilience.
• Heat Resistance: PC-ABS has excellent thermal stability, allowing parts to perform well in high-temperature environments compared to standard ABS.
• Flexibility: The addition of ABS gives PC-ABS better flexibility than pure polycarbonate, making it suitable for parts that require some flexibility without sacrificing strength.
• Dimensional Stability: It maintains good dimensional accuracy, which is essential for prototyping and end-use parts that need precision.
• Versatility: PC-ABS can be used across a wide range of industries, from automotive to consumer products, thanks to its strength, durability, and heat resistance.

Disadvantages:

• Printability Challenges: Like other high-performance materials, PC-ABS can be more difficult to print due to its sensitivity to temperature changes and its tendency to warp. A heated build chamber and precise temperature control are often required.
• Higher Cost: PC-ABS is more expensive than standard FDM materials like PLA or ABS, which may increase production costs, especially for large-scale projects.
• Moisture Sensitivity: PC-ABS is hygroscopic, meaning it absorbs moisture from the air, which can lead to printing issues or weakened part properties. Proper storage in dry conditions is necessary.
• Post-Processing Requirements: Parts printed in PC-ABS may require more post-processing, such as smoothing or support removal, to achieve optimal surface finish and aesthetic quality.
• Limited Color Options: Typically, PC-ABS is only available in limited color options, such as opaque black, which may restrict design flexibility when specific colors are required.
