About Us

SD3D was founded by Bennett Berger and David Feeney in 2013 to provide a one-stop-shop for 3D printing, scanning and design services in San Diego, CA. Since then, SD3D has grown out of the confines of San Diego and matured into an international brand with the bold mission of enabling fully automated industrial additive manufacturing.

With several years of 3D printing industry experience,  we have developed proprietary technologies and processes allowing us to provide the most affordable and reliable 3D printing services available from prototype through production. From the minor parts you need printed to complete design jobs, we will be sure to be accommodating and assist you in any way we can to turn your project into reality.  Our Fulfillment & Design facilities are currently located in San Diego, California and Dallas, Texas; but we can ship orders anywhere in the world. Contact us today to find out how we can help with your project!

Why choose SD3D Printing? 

Additive manufacturing has been around for decades, but the technology is only just now becoming cost effective enough for individuals and small businesses to take full advantage of the opportunities that 3D printing has to offer. At SD3D, we have developed proprietary processes and technologies which allow us to leverage fully automated 3D printing platforms to provide accurate and affordable rapid prototyping for both one-off prototypes as well as large production runs.

David Feeney

David Feeney

Founder/CEO

David is an experienced manufacturing engineer, project manager and entrepreneur. With six years of direct experience in the automotive and industrial equipment industries as a manufacturing engineer and project manager, David understands the needs of the target client extremely well. Prior to co-founding SD3D, David worked at Aptera Motors as a project manager for over a dozen electrical and mechanical engineers. David later worked as a manufacturing engineer for the Large Compressor Set and Mechanical Drive (LCSMD) division for Solar Turbines. In this role David was solely responsible for fixing any design or manufacturing issues prior to hitting the assembly line on over $100 million worth of equipment annually. David holds a bachelor’s of science degree in mechanical engineering from San Diego State University and is EIT accredited with the California Board for Professional Engineers.

Bennett Berger

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.

Sean Aranda

Sean Aranda

Operations Manager

Sean graduated from SDSU with a Bachelors of Science in Business Management and is currently head of operations at SD3D. Sean became very familiar with 3D printing over a year ago and has extensive experience with material variations and profile settings required for a successful print.
Sean is in charge of all orders and day to day maintenance of the production machines. Along with operations management, Sean is experienced in marketing and graphic design. He has put a lot of what he learned into SD3D's free A-Z 3D Printing Handbook - making all of the graphics and creating all of the content.

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.
