4D printing of modified polycaprolactone with self-healing abilities – Presented by Marta Invernizzi, Politecnico di Milano at the 3rd edition of 4D Printing & Meta Materials Conference, which takes place on 18 April 2018 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.
In this work a 4D printed shape memory polymer with self-healing abilities is presented. The shape memory effect is provided by a polycaprolactone (PCL), while the self-healing behavior by 2-ureido-4[1H]pyrimidinone units (UPy). To print them in a DLP printer, a common solvent was added. Printed specimens show a stiffness comparable to neat PCL, but higher elongation at break. To demonstrate the feasibility as sensor for soft robotics an opposite thumb was printed and subjected to the shape memory effect after a healing process.
