ExOne Starts Network to Supply 3DP Sand Molds, Cores

Aug. 4, 2020
The developer of binder-jet printing machines and technology will supply molds and cores for casting a range of metal alloys, from over 40 3D printers at pattern shops and foundries in North America.

The ExOne Co. has established a North American network of pattern shops and foundries producing sand molds and cores using its X1 series binder-jet 3D printers. More than 40 printers are available through the network, to produce molds and cores for casting a range of metal alloys, including aluminum, bronze, copper, nickel-based alloys, iron, magnesium, steels, titanium, and zinc.

“The new ExOne Sand 3D Printing network can help manufacturers easily locate an ExOne sand 3D printer that best meets their needs,” stated CEO John Hartner. “What’s more, our network can help ensure a steady supply of sand molds and cores for metal castings, especially during a crisis, as well as enable reshoring of key parts that may be difficult to ship during the ongoing COVID-19 pandemic.”

In addition to the speed of production, the network is able to print molds and cores as single units, reducing the time and errors incurred for mold and core assembly.

3D printing also allows manufacturers to overcome many design restraints of involved in typical sand mold- and coremaking, and thus to introduce new casting designs.

According to ExOne, new "3D-enabled rigging, riser and gating designs can ensure a high-quality casting that can be simulated and often completed in a single pour."

ExOne develops binder-jet printing systems and also provides 3D-printing services, including on-demand production of parts, as well as engineering and design consulting
