PLA (Polylactic Acid) is a popular, environmentally friendly 3D printing material derived from renewable resources such as cornstarch and sugarcane. It is a biodegradable thermoplastic that offers a relatively low melting point, making it easy to print with and compatible with most FDM (Fused Deposition Modelling) 3D printers.

PLA is well-suited for a variety of applications due to its moderate strength and ease of use. Its low warping characteristics and minimal shrinkage make it ideal for printing intricate, detailed objects, as well as larger parts with good surface quality. PLA is often used in prototyping, architectural models, educational projects, and decorative items, such as figurines, ornaments, and display pieces.

While PLA is not as durable as some other materials like ABS or PETG, it is an excellent choice for projects that prioritize aesthetics, ease of printing, and a lower environmental impact. However, it is not recommended for parts exposed to high temperatures, prolonged sunlight, or heavy mechanical loads, as it can become brittle and degrade over time in such conditions.
