Simple Solutions That Work! Issue 9

ONE. Hazleton Casting Company in Eastern Pennsylvania Hazelton Casting Company has been 3D printing sand molds and cores on-site with a Robotic 3D printer as it can build parts up to 1’ x 2’ x 3’. The system works by filling an open tray on the back side of the print head assembly with sand, which has been premixed with a catalyst, from a hopper delivery system. The robot positions the print head over the table, drops sand and spreads it with a single pass, printing a Furan binder jetting fluid precisely where binding between the sand particles should occur. When setting up for the next pass, the robot rises in height by the PRABH GOWRISANKARAN General Manager EnvisionTEC, Exclusive Strategic Partner of Viridis3D ARTICLE TAKEAWAYS: • Adding Additive Manufacturing technologies to your foundry • Robotic 3D printing to restore the past THREE CUSTOMERS BENEFITTING FROM ROBOTIC 3D PRINTING 26 desired layer thickness for the next layer, repeating the process layer by layer until the final form of the object is complete. The system is relatively fast, printing about 1.5 to 2.5 vertical inches per hour, with accuracy +/- 0.010”. After the print is complete, the system cures in place for about an hour and can be casted. Tony Badamo said the integration into the company’s operations, officially called the Hazleton Casting Center for Additive Manufacturing (HCC-AM) has been simple, just the way foundries like his like it. “We’re very satisfied,” Badamo said. “It’s producing surface finish with at least the same quality as with normal product with no degradation of surface quality, slightly better.” Watch the Video at www.envisiontec.com/hazleton TWO. Metalurges of Conway, Mass. The maker of fine architectural metalwork in Conway, Mass., produces very large metal pieces that hang on large buildings, in hotels and more. “I specialize in high-end architectural pieces that other shops won’t take on,” said Gov Goleman. This is why he turned to Trident Alloys in Springfield, Mass., which owns a robotic 3D printer to produce his unique pieces. “I tend to have clients with very exacting standards. It may take longer for my shop to turn out a piece, but that’s because I am so meticulous, and everything is hand finished.” Hazleton Casting Company in Eastern Pennsylvania
