Sand Castings in Just a Few Hours
The RAM 123 from EnvisionTEC and Viridis3D is the fastest, most flexible robotic 3D printing platform in the foundry 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.
Foundries will appreciate the speed with which the system prints — and how fast their operation can be up and running with the new technology. What’s more, the RAM 123 uses less sand and is substantially less expensive than other sand casting 3D printers on the market today. In fact, the Viridis3D system is 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.
