摘要：PLA or polylactic acid is a thermoplastic made from renewable sources. Thanks to its environmental value compared to petroleum sourced materials, it is widely used in 3D printing industry. Due to the advantages of additive manufacturing in terms of cost and time consumption, many industries are using these technologies to re-engineer parts or assemblies to optimize their products. However, the properties given by the supplier are not conforming to the final printed product. This issue can be dangerous, especially when these products are used in the biomedical fields or toys for children or other sensitive areas. The aim of this paper is to outline the difference between the final properties and the primary ones. The samples are tested in traction following the ASTM D638 Standard. The specificities of the standard in terms of specimen dimensions and test methodologies have been respected. The results demonstrated that there is a difference between the performance of the material before and after using a 3d printer.
