About Me

Eric retrieving 3D printed face shields

What is more interesting than learning 3D printing? Yes, learning 3D printing from kids like me. I am a 11-year-old boy from the 5th grade in the Jackson Walnut Park School in Newton, MA. Well, I don't like to brag my achievements but I'd better to list my relevant credentials here for you to choose the right teacher: a math lover and 3D designer with National 1st Place in Math Kangaroo, MOEMS-E Gold Pin, AMC 8 Honor Roll, and 99% in medium level SSAT. In my free time, I'm also passionate about skiing and sailing. Now stuck at home, I understand how bored kids like me may feel. That's why I started offering free ZOOM lessons to fellow kiddos. While teaching kids 3D printing, I also hope to have more kids join our efforts in helping doctors and nurses fight coronavirus by 3D printing Personal Protective Equipment. We had run a successful fundraiser and we are now printing the 3D face shields. Email me at if you are interested in joining our Kids Print face shields to Protect medics (KPP) project. Together we are strong.
