The car is a symbol of identity. This is already a law in society. The more internal reason is that cars make men more attractive. In the process of driving a vehicle, a man strengthens or expands the desire to conquer. In other words, the element of desire in the desire, the steering wheel with the leather belt tilted, how many men are eager to grasp? But how much do you know about the engine of your car?
If you are eager to learn more, have you ever thought about dismantling your car at home? Recently, mechanical engineer Eric Harrell shared a 35% print model with a full-featured Subaru EJ20 four-cylinder engine with a 35% reduction. Although obviously not a real engine, a perfect 3D printing project will teach you all about how the engine actually works.
In fact, if you are familiar with this project, it is because this is not Eric's first 3D printing engine. The user of the mechanical engineer "ericthepoolboy" uploaded and shared the 22RE Toyota engine model he reconstructed with 3D modeling software SolidWorks. He reduced the 35% ratio so that he could print the final part with RepRap Prusa 3D. Converted to STL format by modeling, a total of 80 parts are assembled together (without bolts and bearings). Eric estimates that it takes 1 kilogram of consumables to complete the model.
So, when you no longer need any air outlets, this cool model can be hooked up to a small motor. The result is a fantastic, “functional†engine model that highlights how the engine functions work – a lively and fun course for car lovers of all ages.
Mechanical engineer Eric Harrell explained that the engine was a little more difficult than the Toyota project - it was touted as one of the most difficult projects at the Thingiverse. “So the best option is to print the model that he was familiar with before, if you choose to print this item. The scale is once again reduced to 35%.
But like the Toyota series, it is completely designed using SolidWorks. Although Eric Harrell does not share SolidWorks files, all 3D printed files can be downloaded from Thingiverse. Subaru's engine model is designed to be printed at home with a 3D printer . In fact, its function is a slightly smaller engine block than the Toyota 22RE. He actually used the Prusa i3 RepRap desktop printer to print for just $200. The above facts show that your home small printer can fully print out the model. Depending on your hardware, some support may be needed, Eric added. The thickness of the parts is 0.2 mm and the filling is 20%-40%.
Eric Harrell is already looking for his next car-related 3D printing project. Eric explained: "Next I will make an AWD transmission or LS1 for the engine. I would be grateful if anyone can provide engine model assistance."
