Hello everyone, I would like to now, witch part of your car, truck, bike ... you hated the most, who breaks the easiest, or has terrible wear rates and severely needs to be rethought.
I now this isn't the usual type of question asked here, but I think this place is the best, I am sure there are experienced people who had trouble with obsolete mechanical parts.

Thank you very much for any answer.

Re: Car Optimisation Sign In

hello, I am studying for a school project additive manufacturing and I would like to analyze a current mechanism in order to imagine how I could design it with this new manufacturing. So I am looking for underachieved pieces due to the constraint of subractive manufacturing (forging, carving...) and show the potential of additive manufacturing (direct metal laser stingering for the most part)
I love this new type of manufacturing and as a future engineer, I am very fond in it. I am not specialized yet, but I will try to do best with my knowledge in Industry, Fabrication processes Mater capabilities Thermodynamics and Modelisation to show a little bit of this revolution.

Every car has it's specific weaknesses. They differ from one make to another. It's usually not metal parts that fail. It's the rubber bushings, the bearings, the rubber parts that deteriorate, electrical components that fail for various different reasons, some in the design, some in the placement. Aluminum parts that corrode, plastic that that fails due to constant temperature changes and extremes.

Much of the failures are due to engineering and design flaws and many are due to just plain cost to manufacture and weight. They are always looking for places to shave weight and costs at the expense of the durability of the component.

Basically your looking for something that is metal on a vehicle that is a common failure item and you want to enhance on its design by utilizing laser sintering?

GM 4T60E and 4L60E factory reverse reaction drum and sun shells. The aftermarket does make beefer shells.

1997-2007 Ford 4.6L, 5.4L, and 6.8L 2 valve cylinder heads blowing spark plugs due to poor design of the spark plug hole threading. Google TSB 07-15-2.

Ford 4.6L and 5.4L 3 valve engine cam phaser locking pin issue. Pin wears out or breaks and causes phaser knock.

Ford 3.0L (ohv), 3.8L, and 4.2L cam sensor syncronizer shaft bushing wears prematurely causing chirping noises or causes cam sensor window to contact hall effect sensor.

There is a whole lot more, but those are some I can think of off the top of my head that could be improved upon.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
