Ordinary PLA granules, which are composed solely of polylactic acid and are transparent, are primarily used for research purposes. These granules, when converted into filament, exhibit high brittleness and lack sufficient resistance when exposed to environmental factors and moisture. As a result, they are not particularly suitable for producing filaments for 3D printing.
Another type of granule, known as PLA+, includes additives that minimize the drawbacks of PLA filament. Its desirable properties have made it a popular choice for producing 3D printing filaments, positioning it among the top materials available. These filaments can be used for printing at low temperatures, do not require high energy, are easy to print with, and produce parts that can be utilized for a variety of applications.
