A new way of 3D printing soft materials such as gels and collagens offers a major step forward in the manufacture of artificial medical implants.

 .

Developed by researchers at the University of Birmingham , the technique could be used to print soft biomaterials that could be used to repair defects in the body.

 .

Printing soft materials using additive manufacturing has been a big challenge for scientists because if they are not supported, they sag and lose their shape. The new technique, called Suspended Layer Additive Manufacturing (SLAM), uses a polymer-based hydrogel in which the particles have been manipulated to create a self-healing gel.

 .

Liquids or gels can be injected directly into this medium and built up in layers to create a 3D shape. New method for printing biomaterials The method offers an alternative to existing techniques which use gels that have been minced to form a slurry bath […]
