Story summary

Researchers from South Korea and the U.S. created a 3D printing device for bone fractures using a modified glue gun.
The device delivers bone grafts during surgery with hydroxyapatite and polycaprolactone filament.
This approach enhances healing while protecting surrounding tissue and allows real-time fabrication.
The material releases antibiotics to lower post-surgery infection risks.
Rabbit tests showed improved bone regeneration without infection or necrosis; human trials are planned.
