Development of functional 3D printable materials

This project aims to the production of functional materials through 3D printing technology in order to fabricate devices in sensor, optical and soft robotics field. Through a precise control of the materials’ composition it is possible to obtain the desired properties (optical, magnetic, electrical,…) without affecting the processability using additive manufacturing technologies. Moreover taking advantage of the characteristics of 3D printing such as possibility to obtain process multimaterials, high precision and flexibility in the design, it is possible to produce devices in which the synergistic effect of material and design allow to achieve superior properties.

In this frame we are developing devices in different areas such as selective permeation of gases, soft robotics, optics and objects with controllable surface properties.

The activities performed are supported by DeFLECT and SMART3D regional projects and university’s project “Joint Projects with Top Universities”.
