PLA filament is the most popular 3D printing filament on the market today. It serves the needs of hobbyists, prototype makers, and manufacturers. The reason for its popularity is its wide tolerance to printing profiles. PLA and PLA+ can be printed with temperatures ranging between 190 to 200 often, without much discernable print differences. PLA+ also handles features such as overhang and supports very well. The key reason is its ability to rapidly cool during printing.
