Exploring the possibilities for novel materials Brightlands Materials Center, a Netherlands-based R&D facility, has commenced a four-year collaborative project to develop new polymeric materials for use in 4D and 3D printing.

4D printing is a term increasingly popular with enterprises seeking to describe how a 3D print can change its form over time.

Project - Polymers - Vitrimers - Properties - Self-healing

This project will focus on unique and dynamic polymers, like vitrimers that demonstrate unusual properties such as self-healing, to lead to new science-based applications with additive manufacturing.

The partners of this project include the Eindhoven University of Technology (TU/e), the University of Maastricht (UM), DSM, a science-based solutions company and 3D printed medical implant specialist Xilloc Medical.

With properties such as tunable or high elasticity, responsiveness to magnetic fields and structural reversibility, smart materials have helped produce the world’s most stretchable 3D printed elastomer, as well as a shrinkable smart ink that enables objects to change size and colour through a reaction to external stimulus.

Step - Printing - Technology - Object - Research

Going a step further, 4D printing is an emerging technology that allows a 3D printed object to transform. Previous research that produced a shapeshifting chess piece made and a self-folding 3D printed tulip have shown the potential for applications in medicine and consumer products.

Intending to address three main research areas, the Brightlands Materials Center project aims to improve current additive manufacturing processes using the recently developed concepts of dynamic and reversible chemistry.

Research - Area - Selective - Laser - Sintering

The first research area is laser sintering. Selective laser sintering (SLS) has faced the disadvantage of having poor mechanical properties, that is, a reduced strength in the z-axis and limited...
