About Coex

Coex was founded in 1996, as a manufacturer of plastic spiral book bindings. In 2016 Coex realized that manufacturing a PVC monofilament was very similar to the way that 3D filaments were being made.  It was at that time that Coex made it's first spool of ABS material and entered the 3D printing industry.  From that first spool of ABS, Coex has continued to build a staff of talented team members that work hard every day to research, listen to our customers and add materials to expand deeper into the ever evolving world of 3D printing.  

Todd Louthain Coex

Todd Louthain, Owner / Director of Sales

Todd joined the Coex team in April of 2020 and dove head-first into the position leading the business and heading up Sales and Marketing. As Todd continued to learn more about the business and about the exciting future of Additive Manufacturing he made the decision to purchase the business from the previous owners and turn Coex 3D into a truly employee owned business.  “With our team having an ownership interest in the business we are constantly focused on producing filaments that meet our own high standards of quality and performance” says Todd.

Todd has a degree in Marketing and Business Administration but really has a passion for creating and maintaining customer relationships and learning new things.  He also has a talent for examining how things work and what it takes to maximize production which has come from his 20+ years of working in and around manufacturing environments.

Todd loves any opportunity to speak with our customers, suppliers, and delivery folks and makes it clear that *everyone* he meets is an opportunity for him to learn something new.  Outside of his Coex life, you can generally find him out in his workshop at home or riding his Harley-Davidson Street Glide with his wife Joy on the seat behind him.  He is a fun-loving, adventurous guy with a big smile and a big heart, always ready with an entertaining story or joke.


Josh Bonnin, Director of Operations / Print Center Manager

Josh joined the Coex team in 2020 after working as an engineer with an arcade game company since 2009. His designs are in many arcades around the world.  He brings years of technical and 3d printing knowledge that helps our customers and control our quality. Josh is a Mechanical Engineer with a passion for, not only for 3d printing capabilities today, but also for what 3d printing could be in the future.

When Josh isn’t helping customers or printing, he enjoys spending time with his family, playing around with the latest tech, or just relaxing on his boat with his wife Erin.
