Eric Harwell has produced a fully working Camaro LS3 V8 engine using a 3d printer.
Working model of a Chevy Camaro LS3 V8 engine.
Over 200 hours of printing!!! Engine block alone was 72 hours.
Modeled from cad files, pictures, specs, and service diagrams of the engine. I did not have the actual engine for this one.
It assembles just like the real thing!!!
