Allowing cells and tissues to develop ex vivo on 3D polymer frameworks has become a vital part of studying biological processes.

 .

Additive techniques based on 3D printing are a key aspect of both manufacturing the frameworks and successfully embedding the cells within them, but the materials involved need to be carefully selected and the printing operation must not damage the cells.

 .

A project at Vienna’s TU Wien has now developed a high-resolution bioprinting process that allows cells to be embedded within a 3D matrix with micrometer precision, and at a printing speed of one meter per second, said to be orders of magnitude faster than previously possible. The work was published in Advanced Healthcare Materials . “The behavior of a cell depends crucially on the mechanical, chemical and geometric properties of its […]
