3D Printed Ketchup Cap


It’s a well-known and universal problem: watery ketchup or mustard.

We have all experienced that condiment bottle that leaves a good meal soggy and less than desirable. Now, thanks to two high school students and a 3D printer, the problem of watery ketchup may be a thing of the past.

The two students from Liberty, Missouri, Tyler Richards and Jonathon Thompson, both 18, have designed a new condiment cap that keeps the water in while letting the condiments out. What started as a high school project in a program at the North Liberty High School has turned into what the two students hope to be a business venture in the future. Originally, the ketchup cap was part of a school program that was designed to provide students with a more hands-on approach to the latest technology.

Richards and Thompson spent around a week collaborating ideas to bring their vision to life. They used a Stratastys Mojo desktop printer to finally print the 3D model of the little mushroom shaped cap that allowed the ketchup to come out, while holding back the watery substance.

The 3D printed ketchup cap idea was initially denied by the student’s teacher. But the students pushed forward – gathering surveys and research to back up their theory and idea, eventually convincing their teacher to let them proceed.

The cap costs around 22 cents to produce, and the students’ research indicates that consumers might be willing to pay $3 for it. They are optimistic and hopeful that their idea will go from a school project to a business venture.
