Making its debut earlier this year at the ConExpo-Con/Agg trade show for the construction industries was the first fully functional excavator to feature major components produced through 3D printing. A descendent of the 3D-printed car, Project AME (Advanced Manufacturing Excavator) was conceived when members of the Center for Compact and Efficient Fluid Power toured the Oak Ridge National Laboratory facility where the 3D-printed car was made.
According to Oak Ridge National Laboratory:
“By utilizing different 3D printing platforms, materials and processes, researchers were able to show the seamless integration of parts working together on one excavator. The cab where the operator sits, the large hydraulically articulated arm and the heat exchanger were all printed at the Department of Energy's Manufacturing Demonstration Facility (MDF) located at Oak Ridge.”
Those three components were made via three different additive processes, as follows:
- The cab, made of fiber-reinforced polymer, was 3D printed on the MDF's Cincinnati Incorporated Big Area Additive Manufacturing machine.
- The arm was 3D printed in carbon steel using a robotic metal additive system developed by Wolf Robotics and Lincoln Electric. One significant feature: the 3D-printed component allowed for hydraulics to run through channels integrated into the solid part.
- The heat exchanger was made on a powder-bed AM machine from Concept Laser at Volunteer Aerospace in Knoxville, Tennessee.
Oak Ridge National Laboratory worked with student designers from the University of Illinois, the University of Minnesota and Georgia Tech to create novel designs for all of these components.
Want to visit the MDF where Oak Ridge National Laboratory does its additive work? Here’s your chance: This year’s Additive Manufacturing Conference (taking place October 10-12 in Knoxville) includes a tour of this facility.
