Scientists created the first practical bioresorbable 3D-printed airway stent

Various injuries and diseases cause the main bronchi or the trachea to narrow, which then makes breathing very difficult and people may suffer from the lack of oxygen. Surgical methods can bring quick relief, but metal or silicone stents usually require other surgeries. New study showed that 3D printable bioresorbable airway stents could be the answer in these situations.

Metal airway stents have to be surgically removed, which is another invasive surgery, while silicone ones sometimes move away
