Researchers at the National Institute of Standards and Technology ( NIST ) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision.

 .

Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can be inserted into the human body.

 .

A standard 3D printer makes solid structures by creating sheets of material — typically plastic or rubber — and building them up layer by layer, like a lasagna, until the entire object is created. For further information see the IDTechEx report on 3D Printing in the Medical and Dental Industry 2019 – 2029 . Using a 3D printer to fabricate an object made of gel is a ” bit more of a delicate […]
