Providing Both Conventional & 3D Printing Processes Adds up to Give Foundries More

We are the only conventional core shop to commercialized 3D sand printing. We work with foundries to determine which process – conventional or 3D printing – is right for their project, based on factors such as deadline, part design and tooling availability. The fact that we can offer BOTH processes means foundries get the best of both worlds! There are even times when we use both conventional AND 3D printing for the same order, in what we call the Dual Path. Click the button to learn more about how the Dual Path is saving customers time and money.

“There is a need for rapid development and tooling-less molding, so when a customer orders five pieces a year, we can actually make five pieces a year. We don’t have to make our minimum order which might be five hundred. Having a partnership with Humtown has been very valuable for us.”

– Tom Kayser, OSCO Industries

“In today’s world, we are seeing a greater and greater demand for rapid prototyping. In working with Humtown, we were able to give a casting to a customer in less than two weeks, which is a pretty amazing lead time. The service and rapid turnaround is the key selling point for us for 3D printed sand cores and molds.”

– Bob Braun, Wisconsin Aluminum Foundry

“Additive manufacturing is extremely important to us because it is the future of the casting industry. Over the past few years, Humtown has revolutionized what they do and how they do it, by bringing additive manufacturing into the picture. They’ve brought us more solutions, better solutions, faster solutions than we’ve seen in the past, and we’re happy to partner with them.”

– Andy Renkey, President of Harmony Castings
