Announcement by Servier and Poietis of scientific partnership in 4D bioprinting of liver tissues

Paris and Pessac, France – 19 September 2018 – Servier, an independent international pharmaceutical company, and Poietis, a leader in the production of living bioprinted tissues, have announced a scientific partnership to use Poietis’s 4D bioprinting technology for the development and production of liver tissues.

This partnership seeks to improve the detection of drug-induced liver lesions as early as the preclinical trial phase. Such lesions are rare1 but can have serious consequences for patients. This hepatotoxic2 potential is poorly detected by current preclinical models. Beyond animal models, various models based on human cell cultures are available, but most lack longevity and complexity, which limits their usefulness in toxicology. Poietis’s 4D bioprinting technology has emerged as an innovative technology capable of helping to overcome these limitations.

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.

UK Team Experiments with 4D Printing Fabrication of Artificial Muscles

3D printing technology has impacted scientific research significantly, especially when it comes to replicating the inner workings of living beings. Recently, in the case of a team of researchers based at UK’s Nottingham Trent University, the replication of organic structures is taking on a whole new dimension.
