Revolutionizing Sand Casting with Stratasys FDM Technology

Sand casting remains one of the most versatile metal‑forming techniques. By impressing a pattern into sand, a cavity is created that can be filled with a wide range of metal alloys. From tiny door handles to large engine blocks, this method delivers high‑quality parts across countless industries.

Recent advances in additive manufacturing (AM) are reshaping the traditional sand‑casting workflow. By employing Stratasys FDM technology, manufacturers can skip the labor‑intensive and costly step of machining physical patterns. AM-produced patterns provide the same compressive strength required for sand molds while drastically cutting lead times.

Melron Corporation, a leading window‑hardware manufacturer, has adopted Stratasys FDM to produce high‑margin, low‑volume sand‑cast parts. Historically, Melron outsourced the machining of aluminum matchplates—a costly and time‑consuming process. Switching to FDM has slashed both cost and lead time, allowing the company to respond more quickly to market demands. Dan Schaupp, Manager at Melron, notes: “FDM is facilitating our transition to new markets by enabling us to produce matchplates at a lower cost and in less time than ever before.”

Reported Savings from FDM Adoption

Other industry leaders—Danko Arlington, Rock Island Arsenal, and Bradken—have successfully integrated FDM into their sand‑casting operations. As skilled pattern makers become scarce, these companies are turning to AM to maintain quality while improving productivity.
