New 4D Printing technique developed by TU Delft researchers has potential to improve bone implants

Researchers at TU Delft have combined origami techniques and 3D printing to create flat structures that can fold themselves into 3D structures (for example a tulip). The structures self-fold according to a pre-planned sequence, with some parts folding sooner than others. Usually, expensive printers and special materials are needed for that. But the TU Delft scientists have created a new technique that requires only a common 3D printer and ubiquitous material. Among other applications, their research has the potential to greatly improve bone implants.

In recent years, Amir Zadpoor of TU Delft has become somewhat of an origami master. His team’s work combines the traditional Japanese paper folding art with the more novel technology of 3D printing in order to create constructs that can self-roll, self-twist, self-wrinkle and self-fold into a variety of 3D structures. In 2016, the researchers already demonstrated several self-folding objects. ‘But there were still serious challenges we needed to address’, says Zadpoor.
