Visitors to this week’s CONEXPO-CON/AGG and IFPE 2017 construction expo have been able to witness Project AME (Additive Manufactured Excavator), the world’s first 3D printed excavator, which was developed at the Oak Ridge National Laboratory (ORNL) in Knoxville, Tennessee. Those who like to keep up with construction-related 3D printing news may well have heard of Project AME. Back in June of last year, we reported that a team of talented students from the University of Illinois had won a competition to design the cab (the section where the driver sits) of a 3D printed excavator, which was already under development in preparation for this year’s CONEXPO-CON/AGG and IFPE (International Fluid Power Exposition).
