Auxetic tubular scaffolds via melt electrowriting

Materials & Design, 2020
Auxetics are an interesting class of materials that expand in transverse directions when tensile loading is applied. For example, in contrast to conventional materials, an auxetic tube will increase in diameter when stretched along its axis.

Stiffness of Auxetic Foams [PDF]

, 2017
An optical method is used for measurements of mechanical properties of foams. The method is based on analysis of diffraction pattern and does not require calibration. The measurements of the stiffness were performed for the conventional and auxetic foams.

Influence of porosity and architecture on the mechanical and acoustic properties of FFF‐printed PLA structures

Polymer International, EarlyView.
The influence of porosity and infill pattern (architecture) on the mechanical and acoustic properties of FFF‐printed PLA is investigated. Ultrasonic analysis highlights the dominant role of interlayer porosity, revealing anisotropic behavior and a transition in elastic properties with increasing porosity.
