These three printers, though different in both age and capability, extruded the parts in incredible detail with no hiccups or setbacks. I had three printers at my disposal, the Fortus 450mc, the 250mc, and the Stratasys F170, part of the Stratasys F123 Series. Printing all of these parts was a lot of fun. Once the 3D models were all downloaded, it was time to get printing. The pedal would act as a potentiometer that would regulate the speed of the pistons. I wanted to demonstrate something a little more dynamic, so I planned out a design for a gas pedal (which I will discuss in a later post). Looking at his final design a little closer, I noticed he was powering the DC motor directly from the wall, so the pistons were “firing” at the same speed. A DC motor is attached to a mounting point that connects the motor to the flywheel, meaning the entire thing will run on its own once powered. The entire engine – once assembled – moves freely, with integrated bearing sockets for the crankshaft and camshaft. The parts are extremely detailed have been designed for easy fastening, with pre-cut holes and bores for M3-sized screws. ģD Printed LS3 Engine, courtesy of Eric Harrell.Įric’s design files include the block, cylinders, headers, valve covers, crankshaft and camshaft assemblies, as well as rocker arms and valves. You can find all of his designs on Thingiverse. Eric Harrell (AKA “ ericthepoolboy “) has working models of a Chevy LS3, a Subaru EJ20, a Ford flat head V8, and a Toyota 22RE 4-cylinder engine. I searched online and found what could arguably be the best 3D model of an LS3 engine I’ve see n to date. However, I knew that modelling an engine assembly from scratch was going to take an unreasonable amount of time. I think of myself as “pretty proficient” at 3D modelling and designing. At the end of each part, I’ll include a “Tips n’ Tricks” section where I cover some important bits of information pertaining to the topics discussed in the segment. These next few blogs will be a part-by-part account of the entire project from start to finish. The project was exciting, time consuming, but in the end, totally worth it. I’ve always wanted a V8 engine, but rather than spending over $7000 for one, I figured I’d 3D print one. The sound is raw and distinct, as the pistons fire at offset intervals, which rattles the block a lot more. Traditional small-block V8’s have a certain sonic characteristic to them that sounds guttural and off-balance. the camshaft is a more aggressive 0.551″ lift, and the overall displacement is over 6.1L. The LS3 is an updated version of the LS2 casting, but with bigger bores and a 10.7:1 compression ratio. It was used in the Corvette for 5 years (from 2008 to 2013) and in the Camaro SS for another 5 years (from 2010 to 2015).
