PRINT A SOLAR LEAF IN 3 HOURS

What: A 3D-printed smart solar “tree" that can be plugged into any home outlet to generate power to the home grid and reduce energy bills. The trees also provide a low-cost solar energy option for low-income and disadvantaged communities in California.

Who: Fifteen CSUF undergraduate and graduate students led by assistant professor of mechanical engineering Dr. Sagil James, professor of computer engineering Dr. Kiran George and assistant professor of computer engineering Dr. Rakeshkumar Mahto.

Material: Third-generation flexible thin-film organic solar cells affixed to a tree made of PLA

Time to Print: Two to three​ hours per leaf

Lesson: “With this project, students learn advanced manufacturing simulation software required to successfully perform the job of an entry-level engineer in today's high-tech industries," says Dr. James, adding that “as 3D printing technology becomes more popular, it could offer solutions to the product needs of the world's le​ss fortunate population. It promises to revolutionize developing nations and positively affect millions of lives."
