Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

Designer Eric Harrell designed a model of the Chevy Camaro LS3 V8 engine which is almost completely 3D printable. Hardware kits are available in partnership with MakerRX. You can purchase the full kit (which includes filaments and non-printable components) and get 10% off HatchBox/ColorFabb Filament.

Kits also include all non printed parts (fasteners, bearing, rods), 500 rpm dc motor, speed controller, power connectors, and DC power supply.Overall the model requires over 200 hours of printing, with the engine block alone taking as long as 72 hours. The engine was modeled from CAD files, pictures, specs, and service diagrams of the engine. Harrell did not have the actual engine for this one. As the video shows, tt assembles just like the real thing.

The electric motor that powers it is a 12V 500rpm geared motor.
Shaft Size : 15 x 6mm/0.6″ x 0.24″ (L*D)
Motor Body Length : 43mm/1.7″;Motor Body Diameter : 33mm/1.3″;Thread Diameter : 2.5mm/0.1″
The motor housing will need to be filed down slightly to fit the starter mount.

The plans and files required for printing are available on this Thingiverse page.

The LS3 6.2L is the 430-hp standard engine in the Chevrolet Corvette and is a combination of high technology and performance. The LS3 crate engine comes complete, from the Corvette specific oil pan to the ignition system. It also includes the EFI intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58X reluctor wheel, and 14-inch automatic-transmission flexplate.

Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhancing the LS3’s airflow and broad torque curve.
