Fit-For-Purpose Engineering Solutions with Sand 3D Printing

Demir Engineering uses 3D printed sand for the full tooling factor, supporting oil & gas, mining, and other industrial projects with rapid replacement parts that help limit downtimes.

Canada’s largest energy region sits at the heart of the Province of Alberta and is one of the world’s most active locations for chemical, petrochemical, oil, and gas investments. Demir Engineering in Edmonton invested in binder jetting with the first large-format sand 3D printer offering outsourced production services in Canada. Printing on the S-Max Pro directly from a CAD model, the foundry eliminates the production time of traditional patterns and core boxes. Digital calculations, simulations, and design freedoms are also bringing new efficiencies to improve the casting process.

When an OEM quoted a mining company a five-to-six-month turnaround time for a replacement part, the mining company turned to Demir for a rapid replacement. With an estimated downtime cost of $40,000 per hour, a quick-turn casting was essential. 

After reverse engineering the part from a 3D scan, the team simulated the pour, printed the mold on the S-Max, and sent the brass casting out to be finished machined a mere five days later.

“The geometric possibilities are a lot more free with sand 3D printing, so we can print gating and riser systems that you could never make before.”
