Has anyone used 3D printing for their mods?

I am very curious of materials used; the filament. I've wanted to make some pieces that would act as a mount for fuel pressure regulator on an American Muscle car still with carburetor. My biggest fear is the ability of the material to hold up in the harsh environment under the hood of a car. The heat, and materials in contact with the part made. How it would withstand contact with fuel, oils, venting from crankcase, etc,..

I have a 3d printer, and would say I've used it more for toying around. I would love to be able to really put it to work.

Here is a link to one of my designs using Fusion 360

So far I've really only made some tools to help with tuning. This was an adapter made for syncing none progressive 4 barrel carter AFB carburetor I was working with at the time. I made two of them and they worked quite well. I made them of PLA knowing they would not be subjected to prolonged use. The easy part is the printing. The real work is learning to use the 3d design tools.

Always looking for the next best Filaments. I'm waiting for the Holy Grail. To be able to print at home in Metal with the strength of forged steel that weighs next to nothing.
 
Forged steel that weighs next to nothing? Only if we can break the laws of physics :-)

Best thing on the market to date is PEEK and PEI. Great performance with "high" temperature form stability and chemical resistance, but you're going to need more than a prussa i3 clone to process it. Oh, and then there's the price. As soon as you've printed 250grams you shot more money through your 3d printer than the cost of most DIY eBay kits. But if you're looking for the ultimate materials, here's a manufacturer that'll get you salivating https://www.3dxtech.com/ultra-performance-filaments/

I've been printing a few mods for my car (one failed due to an engineering brain fart, but the others are still going strong), and the best material I've come across so far is Polymaker CoPA; a mix of nylon 6 and nylon 6.6 which is easy to print and is heat resistant up to 180?C (350?F). Don't know about the chemical resistance though, guess I'll have to throw it in some gasoline. It's a bit flexible compared to PLA, but with a good wall thickness it'll easily compare and really is some good stuff indeed. Link http://www.polymaker.com/shop/polymidecopa/

I teach rapid-prototyping at a technical university in Germany and use Fusion 360 in our introductory 3D-modelling courses. It's a brilliant program that is both intuitive to learn and offers a lot of tools to take care of most any projects you can feed into it. If you haven't already, go through and do as many tutorials as you can!
