Muscle damage, like tearing your ACL, can be traumatic and lead to economic as well as functional decline in patients suffering from it. While scientists have designed 3D printed approaches to help strengthen these muscular losses, recent models have been too slow, bulky and non-adaptive to provide patients a true solution. But a new study hopes to change this by creating a hand-held, 3D printing pen that can print bioink directly on patients’ wounds and adhere to each wound’s unique shape.

The study , published last month in American Chemical Society journal, focuses on a specific kind of muscle loss following a traumatic injury called volumetric muscle loss (VML.) Skeletal muscle is typically resilient and able to repair itself easily, but substantial damage to tissue from VML can make this impossible and in turn, can cause a loss of function in the affected area if not treated quickly.
