Researchers at Concordia University have devised a way to solidify liquid into plastic, creating a 3D-printing option that could be used to implement medical implants directly inside a patient’s body. Direct sound printing (DSP) utilizes high-frequency sound waves to accomplish its intended use.

3D-printing has been gaining in popularity
