ExOne offers an innovative environmentally-friendly option, with a binder based on silicate for printing sand molds and cores. Using this binder for printing results in low gas emissions during the casting process. Parts are easily cured using microwave technology.
Many of our directly printed materials (primarily metals) utilize a proprietary aqueous-based binder, which acts as an adhesive, bonding layers of powdered metal together. Once the parts are printed, they are placed into a furnace and the binder is burned out of the parts while powder particles fuse together in a sintering operation.
