Louis Engineer – 3D Design & Innovation
Hi there. I’m Louis Chen — a teenager who loves engineeringI focus on 3D printing and mechanical invention, empowering different people with technology.
3D Printing empowers different people
As a 3D modeling teacher, I taught kids to customize their own models, creating a car, an aerial bicycle, and a mini wind-up vehicle.At Xianzhai village, I established a 3D printing studio, bringing 3D technology to local seniors.

Mechanical inventions
I designed four self-driving cars and a multi-functional smartwatch using an STM32 chip.During my internship, I built seven companion robot prototypes and used them to improve the language abilities of the elderly.
3D Products
