Résumé

The acoustic behavior of 3D printed micro-lattices is investigated to assess the impact of defects induced by the Fused Deposition Modeling technique on the parameters of the equivalent uid medium. It is shown that manufacturing process leads to three types of non-trivial defects: elliptical lament sections, pinch and laments surface rugosity. Not considering these defects may lead to important acoustic predictions errors. Inverse characterization of three samples allows to t the acoustic prediction model considering this kind of defects.
