3D-printers can be used not only for printing of arms and cranial prostheses , but also for the production of synthetic materials with the properties of living tissue. New materials will be cultured to deliver drugs or replace damaged tissues inside the human body.

New 3D printed materials take the form of so-called “drip structures”, which consist of thousands of interconnected water droplets coated with a lipid film. Lipids – organic compounds present in the cells and tissues of the animals. Lipids store energy and are a structural component of cell membranes. Unlike artificial tissue grown from stem cells droplet structures are not contain genetic materials and do not have the ability to replicate (doubling). This is their main advantage.

We’re not trying to create materials that are hard like living tissue, most structures that could perform its function. We have demonstrated the ability to create structures of tens of thousands of related drops. Drops can be printed together with the protein pore channels that run through a grid system and can transmit electrical signals from one part of the network to another, as do the nerves, – says head of research Hagan Bayley, Professor, Department of Chemistry, University of Oxford.


A drop of 50-micron diameter exceeds the size of a living cell to five times. However, the researchers did not find this a problem and promise to reduce the size of the drop. The droplet structure remains stable for several weeks.

We created the structure contains about 35,000 drops. But this is not the limit. It all depends on time and money. In the experiment, we used two types of droplets. There is no reason not to use various other types. There may be more than fifty, – says the professor.

According to one of the study participants, the usual consumer 3D-printers such a seal can not do. Print artificial fabrics need to have a special device. Moreover, the unique “drip printer” is able to do drip structures that after printing are free to take a different form.

We have created a way to dimension the varied produce a new type of soft material. The printed pattern may repeat the behavior of living cells and tissue, – says study co-author Gabriel Villar.

Research on the creation of an analogue of living tissue has been published in the scientific journal Science.
