Brazilian Woman Suffers From Cancer And Loses Her Right Eye,3D Printed Artificial Eyes Help Build New Faces

Jan 15, 2020

A Brazilian woman suffered a facial tumor 30 years ago, causing her right eye and part of her chin to be lost, but recently a hospital in São Paulo used intelligent 3D printing to create artificial eyes and facial skin, which enabled him to have a "new face." 

 

"Agence France-Presse" reported that although Denis, 53, successfully removed facial tumors in 30 years, 20 years later, the tumor cells made a comeback, causing her torture, and she also lost the right part of her face, including Eye and part of chin.

Researchers at a St. Paul's hospital and University of Paulista recently used intelligent 3D printing technology to create artificial eyes and facial skin for her using silicone.

With her "new face", Denise looked at herself in the mirror and was moved. Denise said, "I will feel much better walking on the street today."

 

Researchers at Paulista University are currently using smartphones and 3D printing to create "digital facial impressions" to make "silicone prosthesis" human organs, a groundbreaking method that reduces costs and cuts production time in half.

Lead researcher Sarasal said: "It used to take longer and required hours of manual sculpting, and the process was very invasive and the substance on the patient's face could leave marks."

Denise's plastic surgery began in 2018. Sarasal first implanted a titanium rod in her eye socket to secure the prosthesis. Over the next year, she underwent multiple surgeries to build her own facial cell tissue.

Later, Sarasal used her smartphone to take 15 photos of Denise's face from different angles. These photos were used to make a 3D digital model, and the designer used the model to create "incomplete" parts of Denise's face.

 

Technicians then 3D printed a prototype prosthesis, and they made the final "face and eye" part of the prosthesis from silicone, resin, and synthetic fibers. To make the prosthesis look as realistic as possible, Sarasal's team carefully matched the color to Denise's skin and blue-green eyes. The process of making the final prosthesis takes 12 hours, which is half of the traditional method.
