ExOne has added iron infiltrated with bronze as a new 3D printing material and has increased the suite of binder solutions for its 3D printing process to include phenolic and sodium silicate.
Iron is widely used in the manufacturing of machine tools, automotive parts and general support structures, partly because it is considered cost-effective. According to ExOne, 3D printing of iron-based products allows for the direct creation of more intricate products than traditional manufacturing processes, and it is more cost-effective than using alternate 3D-printing materials such as stainless steel.
Phenolic binder, used with ceramic sand in the 3D printing of molds and cores, enables the casting of higher-heat alloys, creation of higher-strength molds or cores, and improvement in the quality of the casting due to reduced expansion of the mold or core. According to ExOne, the use of sodium silicate binder will reduce or eliminate the release of fumes and gas in the casting process, helping to reduce costs associated with air ventilation, and electrical and maintenance equipment.
