What Is ABS Plastic And Why Does It Have A Shine?

ABS plastic is a type of thermoplastic that is commonly used in 3D printing, consumer products, and other applications. It is known for its impact resistance, affordability, and ease of production. The shine on ABS plastic is due to the way the plastic is molded and finished during the manufacturing process. When ABS plastic is molded, it can create a smooth, glossy surface that reflects light.

The shine on ABS plastic can be desirable in some cases, but in other cases, it can be a problem. For example, if you’re trying to create a matte finish or a textured surface, the shine can be a distraction. Additionally, the shine can make the plastic appear cheap or low-quality, which can be a problem if you’re trying to create a high-end product.

Why Do I Need To Remove The Shine From ABS Plastic?
