GM takes 3D printing beyond prototypes to tools and soon parts


“We’re actually excited in regards to the future alternatives and the way this expertise can develop and actually assist us be extra environment friendly, efficient and actually main in utilizing this expertise going ahead,” Quinn mentioned.

Three-quarters of the elements on the primary bodily model of the midengine Corvette have been 3D printed, GM mentioned. The additive manufacturing group invited the Corvette meeting group to Warren, because it does with most automobiles, for the sluggish construct course of, when the meeting group places all of the elements collectively and evaluates ergonomics and clearance for meeting.

With 3D printing as part of the sluggish construct course of, the group can adapt on the fly, mentioned Quinn, printing enhanced variations of elements to resolve points in actual time.

No earlier sluggish construct mannequin had so many 3D-printed elements, GM mentioned. The expertise allowed the design and engineering groups to diagnose and proper many points earlier than manufacturing. GM additionally used 3D printing to check and implement options such because the retractable hardtop and right-hand drive for worldwide markets.

The evaluations have been “clearly very important as a result of that is the primary midengine Corvette we have ever constructed,” Quinn mentioned. “To not say that the opposite automobiles are simple, however this one is a bit more difficult as a result of it was a primary for us.”
