4D printing of modified polycaprolactone with self-healing abilities – Presented by Marta Invernizzi, Politecnico di Milano

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.

About Marta Invernizzi
I’m a PhD student in Materials Engineering at Politecnico di Milano. I’m actually working on the developement of innovative and smart polymers for the additive manufacturing world. I’m focused on new materials for the aerospace, automotive, electronic and mechanical fields. I tailor the material properties depending on the field requirements (i.e. toughness, conductivity, biodegradability, self healing ability, photoreactivity, etc.).

4D Printing ConferenceAbout the 4D Printing & Meta Materials Conference
The 3rd edition of the 4D Printing & Meta Materials Conference will take place on April 18, 2018, at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands. At the same location, on April 17, 2018, the 3D Printing Materials Conference and the 3D Printing Design & Engineering Conference will be held.

Making and utilizing new materials to improve our life is a defining feature of mankind. We moved on from the stone age, to the bronze age, to the age of silicon and plastic. Now we are at the edge of a new episode, where technological breakthroughs allow us to create, investigate and dream of a total new range of structured forms of matter.

Two fields emerge strongly:

  1. 4D Printing offers a streamlined path from idea to full functionality.
  2. Mechanical metamaterials are structured materials with mechanical properties defined by their structure rather than their composition.

These are highly promising disciplines which develop in a synergistic manner, and which aim at creating entirely new forms of matter, which will lead to applications that have not yet been conceived.

The 4D Printing & Meta Materials Conference will not only cover the academic results but will show how designers and engineers will see future applications and new markets.

Who should attend? Engineers; Designers; Material researchers; Material producers; Academics; anyone who sees potential in 4D Printing and Meta Materials
