Sand Castings in Just A Few Hours
The Robotic Additive Manufacturing systems from EnvisionTEC and Viridis3D are the fastest, most flexible robotic 3D printing options in the foundry and 3D printing industries today.
The RAM 123 from EnvisionTEC and Viridis3D is the fastest, most flexible robotic 3D printing platform in the industry. Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds and cores for the foundry industry. The proprietary system includes easy-to-use software that uses a CAD file to print a mold and core in just a few hours.

Exclusive Binder Jetting Technology
Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds, mold cores and investment casting patterns for foundry applications. The proprietary systems include easy-to-use Viriprint software that uses a CAD file to print a mold and core in just a few hours.
A variety of build envelopes are now offered. The RAM 123 prints pieces up to 1’ x 2’ x 3’, with a RAM 224 (2’ x 2’ x 4’), RAM 236 (2’ x 3’ x 6’), and RAM 336 (3’ x 3’ x 6’) now available. Viridis3D can also develop custom solutions with this scalable solution.
Foundries will appreciate the speed with which the systems prints — and how fast their operation can be up and running with the new technology. What’s more, the RAM systems use less sand and are substantially less expensive than other sand casting 3D printers on the market today. In fact, the Viridis3D systems use about one-third the cost of competing technologies that build in a box.
This disruptive technology brings a new way of production to foundries — instead of shipping castings around the world, raw materials are shipped and files are simply transmitted to 3D printers in strategic locations. The result is castings are poured the same day, only where you need them.
