Mechanical Engineering Students Design an Excavator Cab

It is the new thing about additive manufacturing.


Mechanical engineering students created a 3D printed excavator cab for automotive manufacturing use.

The new age of manufacturing automobiles has dawned upon us. Back in 2014 during the International Manufacturing Technology Show (IMTS), there was a 3D-printed car made by Local Motors, Oak Ridge National Laboratories (ORNL), and other companies. Now ORNL wants to take it further with construction equipment, and plans to 3D print an excavator at next year’s CONEXPO CON/AGG.  What they will produce right at the show is a boom with built-in hydraulics, which will be built in just one print.

On the other hand, mechanical engineering senior students at the University of Illinois have their own take on additive manufacturing of construction equipment – that is through their design of a cab of an excavator, which was a nationwide design contest. The conventional cab has panels for vibration and sound dampening, which the team has strengthened with air pockets into their 3D printed model, while allowing efficient use of structural supports.

It took them an entire semester to design, and produced a 1/16th model as a submission to the contest. A full-scale version of the cab will be at the CONEXPO-CON/AGG in March 2017 joining ORNL’s excavator.
