Which material is most commonly used for 3D printing?

Polylactic Acid (PLA) is most commonly used for 3D printing due to its favorable properties and ease of use. It is a bioplastic derived from renewable resources, such as cornstarch or sugarcane, making it an eco-friendly option in the realm of additive manufacturing. PLA is known for its low printing temperature, which simplifies the 3D printing process and makes it accessible for beginners. Additionally, it generates minimal odor while printing and adheres well to the print bed, enhancing the overall print quality and reliability.

The material also offers a good balance of strength and flexibility, making it suitable for a variety of applications, particularly in prototyping and hobbyist projects. Due to its widespread availability and the support of numerous 3D printers compatible with its use, PLA remains the most popular filament choice among users in the 3D printing community.
