ProtoMars

Hello
I’m Jian! With over a decade of experience spanning mechanical engineering, 3D prototyping, and international manufacturing, I help individuals and small businesses bring their mechanical part designs to life. By leveraging my strong connections with Chinese factories, I offer customized prototype manufacturing services with a focus on quality, efficiency, and transparency. Let me simplify the process so you can focus on what matters most—your innovation.
My Story and Services
Who I Am
I was born and raised in China, where I earned a bachelor’s degree in Mechanical Engineering from one of the nation’s top universities. Over a decade ago, I moved to the United States to pursue graduate studies, focusing on bipedal robotics simulation. However, my passion for hardware led me to transition into hands-on engineering after earning my master’s degree.
My professional journey began at a research company specializing in 3D printing and 3D scanning. For two years, I worked on innovative projects involving precision prototyping. Later, I became a project manager at a contract manufacturing company, where I connected U.S. clients with Chinese factories to produce high-quality machined parts, castings, and forgings, etc. This role allowed me to build a robust network of reliable manufacturing partners in China while gaining expertise in materials like stainless steel, aluminum, brass, plastics, and titanium.
​
Why I Started This Business
Currently, I work full-time in the semiconductor industry, but my passion for mechanical engineering and manufacturing remains strong. I created this side business to help individuals and small businesses who need small-batch or custom prototypes, a niche often overlooked by larger manufacturing firms.
