PLA+ is a type of 3D printer filament that is based on standard PLA, but with extra additives to enhance a wide range of qualities. It addresses many of the common problems that PLA presents, such as the brittle nature, low elongation breaking point, as well as layer adhesion. The only area in which regular PLA beats PLA+ is in tensile strength, although it is a slight difference, and is far outweighed by the plethora of benefits.
