Marshal Haupt

Marshal Haupt

Chief Engineer

Marshal graduated from UC Davis in 2009 with a BSEE degree. He initially began his career working in the design and development of photovoltaic inverters. From there, it was clear that his skillset was better suited to designing and building robotics/control systems.
After five years working in subsea robotics at FMC Technologies, Marshal turned to communication control designs for industrial control equipment. Most recently, Marshal worked with a flow control meter manufacturer on a CANbus communication control network and is using that expertise directly in his role now at SD3D.

Junhua Wei

Junhua Wei

Research Engineer

Junhua graduated from Texas Tech University on 2015 as PhD from Mechanical Engineering Department. His research and work are focused on the 3D printer hardware development, 3D printing materials preparation, and functional device fabrication. He is currently working at PARC, a Xerox company, to continue his research on 3D printing. His role in SD3D is enhancing the FDM printing quality from hardware aspect by establishing theoretical model, determining parameters through experiment, designing mechanical/electric structure, and programming firmware. He has authored over 20 peer-reviewed journal articles and reviewed over 100 articles in the fields of polymer reinforcement; particle functionalization, dispersion, coating, and filming; bio-sensor synthesizing; energy harvest devices fabrication; and prototype hardware developing.

Kiana Duncan

Kiana Duncan

Mechanical Engineer

Kiana graduated from Johns Hopkins University in 2016 with her Bachelors in Mechanical Engineering. She primarily does 3D design work for SD3D and was on a senior design team at Hopkins that created a purely mechanical prosthetic arm for upper-limb amputees at the Walter Reed Military Medical Center. The arm featured automatic cord retraction and improved upon current elbow prostheses in its ease of use, decreased number of moving parts, and overall weight. Her team won the award of Best Project out of sixteen senior projects in the Mechanical Engineering department, and is continuing to be improved so that the team can give the device to patients for testing.
