Introduction
PLA+ is derived from modified 3D printing PLA material, retaining the easy printability of PLA while enhancing toughness and interlayer adhesion. PLA+ is an environmentally friendly material that is easy to print, with a smooth surface on printed parts; it has balanced strength, rigidity, and toughness, with strong impact resistance, making it very suitable for printing functional parts; it is FDA certified for safer use; it can be used for early concept models and rapid prototyping.
