Our Journey From Prototype to Production – Hoosier Pattern

HPI Case Study


Customer: Strand Design; Chicago, Illinois
Part: Fourneau Bread Oven
Batch Size: Prototype to Tooling 
Material Cast: Gray Iron 

What it is: 

The Fourneau Oven is a cast-iron container that goes inside of an oven. It is designed to make bread using the no knead method made famous by Mark Bittman of The New York Times. The device’s walls heat the dough evenly and the enclosed cooking space traps the steam from the baking bread, creating a golden, crispy crust.

Customer Challenge: 

Strand Design came to HPI many different times with multiple design molds for the oven that weren’t possible due to the way it was designed. The designers asked HPI to reengineer the molds to add proper gating and risers to have it done within a short time span. Once the design was tested, it was noted that it was too heavy as one solid piece. 


As designers, Strand Design did not want to hand over the design work to a third party. So, Hoosier Pattern worked side by side with the owners to redesign the oven to make this project a reality. The final design was broken up into parts so the container was easier to handle. The 3D printed sand molds were printed within a really tight schedule and came out perfectly.



Ultimately, Strand Design opted to not only have Hoosier Pattern print the prototypes for the Fourneau Oven, but they decided to have Hoosier Pattern complete the tooling for it as well. Strand Design’s Fourneau Oven is just one of the many projects that proves Hoosier Pattern is the one stop shop for prototyping projects that will ultimately need tooling in a short amount of time. 

HPI Competitive Advantage: 

Hoosier Pattern works very closely with all customers enabling our designers to make changes on the fly to keep all projects moving forward to meet customer’s needs and deadlines. Hoosier Pattern’s 3D sand printer operation is effective and more practical for quick turnaround times. 


It was a very exciting mail day when we recieved our own Fourneau Ovens. Congratulations, Strand Design on this awesome product you have made. Hoosier Pattern is excited and proud to be apart of it. Happy Baking!
