Types of metal for 3D print ??

[cuda hunter]

Aluminum (AlSi10Mg)
Cobalt Chrome
Copper (CuNi2SiCr)
Inconel 718
Stainless Steel (17-4PH and 316L)
Titanium (Ti 6-4)

These are the more common metals that are used in 3D / CNC  printing.
I am wondering what the opinions of you fine folks would be as to using what type of metal on an M46 scoop.
The scoop takes a lot of water and rock abuse due to the front tire.  Aluminum corrodes so I am wondering if Stainless would be a better option? 
The scoop would be painted black instead of organisol coated like the originals.

Hi!

Could you measure the size of one scoop?

I would like to ask around, if it's possible to do here or not.

What is the original material?

Probably the stainless. Another option that would be lower cost and very durable would be ASA CF or GF - CF (carbon fiber) and GF (glass filled) introduce additional properties to the ASA making it stronger and more rigid while being heat resistant and chemical and oil resistant. This type can be used in a home 3D printer and several have decent bed sizes now. I didn't realize the scoops were that small, they might even fit on my own print bed 9.6"x9.6"

When comparing ABS CF (ABS with carbon fiber) and ASA CF (ASA with carbon fiber), the key difference lies in their weather resistance, with ASA CF being significantly more suitable for outdoor applications due to its superior UV stability and resistance to warping, while ABS CF is generally better for indoor use where weather resistance is not a primary concern; both materials gain increased stiffness and strength from the added carbon fiber reinforcement.

12" at it's longest straight point.  I don't think I have a diagonal measurement on that thread.  I'll have to update that.

I look through five pages and didn't find the actual dimensions of the scoop, but tons of pictures of the small dimensional stuff

Post #8.  I will update.

That would definitely require one of the bigger ones. For initial purposes I would definitely farm it out. Whichever company you choose will be able to 3D scan it and do dimensional corrections with CAD. Thinking about it more, metal is probably the better way to do it since you can incorporate the studs into the print. Make sure you get the CAD files for it as well so that way you can have any company do it in the future or yourself when prices come down.

If you need help with anything up here in Denver I'm happy to help, I got plenty of time on my hands right now

Tough call on what metal.
Stainless choice would be 316. This would allow for (careful) fitment adjustments. Probably my first choice.
Second choice for me would be the aluminum.
Titanium and Inconel low on choice for fitment capabilities.
Have to remember that 3D printed metal is similar to cast. There is no grain structure so it is prone to fracturing.
Have the print supplier state the pros and cons for each.

ec_co mentioned the 3D ASA  carbon is what I have landed on for the ebody vents. Very impressed with its overall strength. Pic is untouched printed ASA CF.

An alternate option would be to have a scan printed into core/cavity to use for fiberglass mold. Vacuum molding or even heated compression molding.
