Futuristic Handheld 3D Bioprinter Could Revolutionize Healthcare, Regenerate Organs

By StudyFinds Research

A medical tool that can regrow skin and repair organs is something many people probably think only exists in science-fiction shows. However, it could soon become reality. Scientists have developed a handheld bioprinter that brings modern medicine one step closer to printing functional tissues and organs directly within the human body.

This portable device overcomes the limitations of previous designs, allowing for the printing of multiple materials and precise control over the properties of the printed tissues. With its potential applications in regenerative medicine, drug development, and custom orthotics and prosthetics, this innovation is set to revolutionize healthcare.

Regenerative medicine has made remarkable strides in improving patients’ lives by repairing or regenerating damaged tissues and organs. On-site bioprinting, an extension of 3D printing technology, takes this advancement even further by enabling the synthesis of tissues and organs right inside the body. This approach offers hope for addressing challenges such as the scarcity of organ donors and the risks associated with transplantation.

However, current in situ bioprinting technologies have their limitations. Some devices can only work with specific types of bio ink, while others can only create small patches of tissue at a time. Additionally, the complex designs of these devices make them costly and limit their practical applications.

The research team, including Erik Pagan and Associate Professor Mohsen Akbari from the University of Victoria in Canada, developed a handheld on-site bioprinter with a convenient modular design, that allows the printing of complex biocompatible structures. Akbari’s personal experience with breast cancer motivated him to explore the potential of handheld bioprinting for breast reconstruction and tumor modeling in cancer research.

“Two decades ago, my mother was diagnosed with breast cancer, which eventually led to the removal of her breast. This affected her well-being considerably. It made me realize that a technology like handheld bioprinting could not only help develop personalized implants for breast reconstruction that match the shape and size of the patient’s tissue, but also be used to create tumor models for the study of breast cancer biology,” says Akbari in a media release. “Such applications could significantly improve treatment outcomes for affected patients.”

The standout feature of this handheld device is its multiple bio ink cartridges, each controlled independently by a pneumatic system. This level of control empowers operators to develop structures with the desired properties. The device also includes a cooling module and a light-emitting diode photocuring module, adding further control and versatility.
