Here’s another awesome feat of craftsmanship by Eric Harrell: a working model of a Chevrolet LS3 V8 constructed almost entirely on a 3D printer. Check this out.

You may be familiar with Eric Harrell from a previous model he created: a Subaru EJ20 WRX engine with all its bits constructed entirely on a 3D printer. Eric’s latest project is even more impressive: a working model of the LS3 Chevrolet V8, the version used in the current generation Camaro. And everything on this engine, except for the bearings and threaded fasteners, was produced with 3D printing, too.

Eric accomplished this feat despite having no physical 1:1 version of the engine on hand for reference. “Some parts were modeled from CAD files floating around the internet, while others were modeled from pictures, repair manuals, and diagrams,” he says. Over 200 hours of printing time were required using over two kilograms of PLA plastic filament, with all the work performed on a homebuilt RepRap prusa i3s printer. The cylinder block alone took 72 hours.

If you’d like to tackle this project yourself, Eric has generously made all the printing files available at his Thingiverse page, along with parts kits, an electric motor, the engine stand, and other necessaries. Or he can build you a complete duplicate engine ready to go if you like. Now check out the video below—and prepare to be impressed.
