What I'd actually hope for is a material with similar properties to Ed's, which should be much less expensive (less elaborate 3D printer needed?) & lighter weight than even aluminum.

Even if that isn't affordable, perhaps using the tech to make a molds & cores would be practical, using Ed's pour-able foam for the manifold itself.

Charlie,
Put direct laser metal sintering in your browser. You will find several sources for producing parts directly. Most are still too expensive to be practical. Prices are coming down though.

Subject: [FlyRotary] 'open source' parts

I'm excited to see all the activity on the accessory cover/adapter plate, & don't want to divert any attention. But Ed's post several days ago describing how he made his intake manifold triggered a thought that might need to go on the shelf for next action.

The original idea that started all this was an intake manifold. My intent is to use a very simple manifold similar to Tracy's Otter manifold, but for those who need a more complex layout, what about this:  If Jarrett, or anyone else on here, has access to one of the new '3D printers', doing a manifold should be a piece of cake for anyone with CAD skills (it ain't me...). Apparently, there are 3D printers that can use all manner of materials now. I wonder if you could 'grow' an aluminum or other light/strong/chemical resistant manifold directly in the printer. Something similar to the plastic coiled tube manifolds on new V8's comes to mind.

OK, back under my rock....
