In May 2020, the article “3D printing vertically: Direct ink writing free-standing pillar arrays” was published in “Materials Today” (5 years impact factor of 32,072) ( /j.mattod.2020.01.003) co-authored by researcher Bo Nan, currently in postdoctoral studies at Huazhong University of Science and Technology, in China, and by professor José MF Ferreira, both from DEMaC / CICECO, and the researcher Francisco J. Galindo-Rosales, from CEFT, Department of Chemical Engineering, Faculty of Engineering, University of Porto.

The article presents several examples of uniaxial and periodic printing of pillar arrangements from ceramic pastes with well controlled viscoelastic properties. This promising approach demonstrates the possibility of expanding the applicability of 3D printing using more versatile degrees of freedom and more complex printing instructions.

There are many ideas on how to use such systems for medical and other applications. This innovative work is expected to inspire the scientific community and open interesting paths for the use of advanced materials in the areas of science and technology
