3D Printing

Development of new printable materials


The Doctor Annalisa Chiappone is a Material Engineer, Ph.D. in Materials Science from Politecnico di Torino. She is author of numerous articles on international peer-reviewed journals and chapters on specialistic books.

Currently, her research is principally focused on the development of new printable materials bearing intrinsic functionalities (e.g. electrical conductivity, mechanical strength, optical properties, biocompatibility…). Since 2012 Annalisa Chiappone conduct the Researches of new materials within the Italian Institute of Technology (IIT), Center for Sustainable Future Technologies (https://www.iit.it/).

In February 2015 the Italian Institute of Technology (IIT) team, of which she is part, bought a first DLP printer for the lab, it was a machine from Robotfactory. Currently, they are using two Robotfactory machines, 3DLPrinter-HD 2.0+ model, for their 3D Printing tests on new formulations.

Doctor Annalisa Chiappone has been invited to attend and give a talk at the ‘Additive Manufacturing and Functional Materials Symposium’ that it was held in June 22-23, 2017 at University of Washington, in Seattle (USA) (https://artsci.washington.edu/content/3-d-printing-symposium).

On occasion of an interview to a web magazine specialized on 3D Printing, the “Women in 3D Printing” that is dedicated to promoting, supporting and inspiring women who are using Additive Manufacturing technologies, the doctor spoke about us too… The complete interview is available on website:


The last published scientific article by the IIT team, of which Annalisa Chiappone is part, presents the results of a study on graphene oxide-based 3D printable composites. This study demonstrates that, PEO-acrylates composite containing graphene oxide (GO) can be easily 3D printed from water based formulations. Exploiting the good water affinity of graphene oxide, the filler can be easily dispersed in oligomers formulations and printed by using a DLP equipment. Then the UV post curing process, which is always mandatory after a DLP process, is exploited to in situ reduce the graphene oxide embedded in the matrix; similarly a thermal treatment is also investigated as post process.

The prepared formulations were printed using a Robotfactory 3DLPrinter-HD 2.0+ and the obtained samples underwent a post curing process performed with UV Oven also provided by Robotfactory equipped with a rotating platform.
