additives utilized in a typical foundry or core shop. Because of this, resin suppliers are actively participating in further development of these resin technologies and their capabilities within additivemanufacturing. New advances in binder technology, combined with equipment innovations, are enabling the use of additional binder chemistries such as inorganic silicate and phenolic binders, allowing foundries to expand beyond Furan systems. HA International currently offers 3D Jet Resin, which was engineered exclusively for additive manufacturing equipment. As a result of the rapid advancement of this market, HA International has dedicated significant resources to advancing the resin technology within our portfolio in additive manufacturing. As a result, the future of printing technology for coremakingwill offer great flexibility and adaptability to current foundry methods and raw materials. Mr. Frush commented that partnerships between the industry, equipment and binder suppliers, as well as technology centers, is fundamental to advancing the capabilities of additive manufacturing. We already see theseefforts yieldingpositive results, as more foundries and OEM’s are using this technology to address some of their more complicated, and in some instances, even higher volume jobs. WHERE IS THE TECHNOLOGY GOING? The boom that 3D printing has had in recent years has driven the costs associated to this manufacturing process down compared to years ago. This demand, along with the increased flexibility and advanced binder technologywill undoubtedly expandtheneedfor this technology platform. More than just printing services, the technology centers involved in additive manufacturing are advancing the importance of integrating software modeling for solidification and core configurations toensuremaximum equipment ut i l i zat ion and ultimately, superior casting results. Cu r r en t l y , Add i t i ve ( 3D) Manufacturing is in the early stages of innovation providing a competitive alternative to existing technologies and one that has the potential to cause a paradigm shift in the casting marketplace.
