The study of degradation and mechanical properties of poly(lactic) acid (PLA) based 3D printed filament

Additive manufacturing, commonly known as 3D printing technology, has become one of the mainstream processes in the manufacturing industry due to its advantages over conventional manufacturing, which have piqued the public’s interest. This study aims to focus on the influence of thermal conditions o...
