Researchers at Canada’s University of Toronto Engineering and Sunnybrook Hospital have created a handheld three-dimensional skin printer that can accelerate healing from large burns.

The device covers wounds with a uniform sheet of biomaterial, using a bio ink of mesenchymal stroma cells that differentiate into specialized cell types to promote skin regeneration and reduce scarring.

The prototype device features a single-use microfluidic printhead to guarantee sterilization, while a soft wheel follows the printhead's track to enable better control for wider wounds.

Sunnybrook's Marc Jeschke said, "Once it's used in an operating room, I think this printer will be a game-changer in saving lives. With a device like this, it could change the entirety of how we practice burn and trauma care."
