摘要：
Given the production method used in additive manufacturing (successive layers build-up) anisotropy is to be expected. This study is oriented on the anisotropy of the mechanical properties in compression for 3D printed parts made of PLA that are used for medical applications. The ratio of elastic modulus on longitudinal to the transverse direction was found to be 0.48 and 0.59 for the yield strength, showing that an accentuated anisotropy appears. Thermal processing was performed in order to ameliorate the anisotropy and the ratio value was risen to 0.73 for the elastic modulus and 0.86 for the yield strength.
