No, I've been using PLA, it doesn't seem to warp when printing.  Melting temperature is about 180C, so it should hold up at least to dyno temperatures.

Wish your product was available few years ago; would have been much cleaner and easier.
Here's mine; finished Oct 2014



BTW link was from PB

Cool setup!  Did you ever dyno it, or run it at the track?

Finished up and bolted together:












Also test fit the Holley LS tops on there to see how they look.  Turns out that my bolt holes are off by a few thousandths, though, making it difficult to get all the bolts installed.  I'm guessing this is because the plastic on the 3D print shrunk a little over the 18" length of the plenum, so that when I adjusted the holes to fit the Holley tops, they moved a little too much.  I will be enlarging or slotting the bolt holes to correct for this problem.  Fortunately this is not a big deal; it would be a shame to scrap that plenum.

First photo below is with the Holley 2X4 top, and the second is with the front facing throttle body for EFI top, which is the one my customer will be running. 

I like this thing so much, I may have to get me a tunnel port  ;D ;D

Very cool Jay, using a readily available top. Do you do any pressure or vacuum testing on these assemblies?

Nope, I rely on the O-rings on both ends of the runners to seal, and also an O-ring seal from the plenum to the Holley top.  You can see the groove in the top of the plenum; a 1/8" diameter O-ring goes in there for sealing.  I'm pretty sure the O-rings will make for a trouble-free seal.

With it being billet, it shouldn't be required unless there was a problem with the seals.

That EFI top looks perfect for a turbo set-up. The only drawback I can see is you lose easy access to the adapter cover to the lifter area. The single bottom bolt on the runners look like they'd be difficult to get at. At least more difficult than a standard intake.

You are right about that Doug, in addition to there being 24 bolts to remove the intake from the intake adapter, the bottom bolts require a 3/8 drive 12" extension, plus a U-joint, and a 3/16" allen head socket to tighten or loosen the bottom bolts.  They're not hugely difficult, though, just not as easy as the 12 bolts on a standard 351C intake.

That looks really nice Jay. Any thoughts on doing a version to suit a SOHC?  Would probably work well with a set of raised port heads.

I am planning an SOHC version, in fact I will probably run one myself next year.  Before I do that though I have to finish another tunnel port version, and then get one ready for the standard FE intake adapter.  So I'm at least several months away from having the SOHC version...

Jay, what a great mind & heart you have for the FE family and the entire system is a work of art !

Wonderful job my friend, wonderful.  ;)

Can you build me a 3d printed 427 Cobra, then create it in a billet body ?   :)

Coincidentally, I had a second customer who was interested in one of these billet intakes for a tunnel port.  This customer wanted to use the intake with a Roots blower.  He purchased the blower and sent it to me so I could get dimensions from it and adapt the intake to mount the blower.  As usual it took me a little longer than expected to get this project done, but I just got it finished up this week.  I think it looks great.  Photos are below, showing the intake manifold, which is slightly modified from the previous one to make it a little stouter, so it will support the blower, plus a blower plate (first picture) that bolts onto the plenum, and the blower itself.  I almost hate to put this in the box and ship it, it looks so good sitting here... ;D ;D ;D
