PLA+ is a 3D printing material that comes in the form of a filament, which is a thin string wound on a spool. It is an improved version of the commonly used PLA material, which is known for its ease of printing and production from renewable resources such as corn starch. The "+" in the name indicates that additives, special admixtures that modify the physical properties of the PLA base material, have been added. The main difference is that PLA+ is significantly tougher and less brittle than standard PLA. In practice, this means that printed objects made from PLA+ are better able to withstand impact and bending, and are less likely to crack when dropped or subjected to mechanical stress. At the same time, it retains most of the advantages of standard PLA, such as its low tendency to curl during printing, which simplifies its use. These features make PLA+ suitable for printing functional parts, mechanical components or models where higher durability than basic PLA is required.
