3D Printing 924 & 944 Parts - Development and Discussion
#46
Although you may not be able to do so with your equipment, would it be possible to make a dash pad? I think it might be possible to construct a metal trame, then in a two-step process, 'print' a foam core, then a vinyl top layer. Because the top surface needs to be both textured and elastic, I think this method of manufacturing lends itself well to this kind of part. Alternatively, a 3D printer capeable of doing metal might be able to make new molds from which to manufacture a part in the more conventional way.
As for the under-intake hose for the NA, aren't those still available new? I just bought one a few months ago.

Couldn't really wedge the TIC up under the intake manifold, but I was able to go for a quick drive a bit earlier. It got up to normal operating temps.
Without knowing the specific emissivity of all the materials in the engine bay the scale on the right is off, but ambient was ~60°F, so applying the scale between that and normal operating temps of the exhaust manifold should get it in the ballpark. I also didn't adjust the parallax so the overlay for visual->IR is a bit off on the close up shots.

Yes indeed. "Cold air intakes" are very rarely that. Even slightly restricted fresh air from outside the engine bay is generally better than no restriction sauna breathing. But you know, the stickers add enough of the HPs and torques to make up for it I'm sure.

But yeah, I like toys

If anything, printing a form and covering that with conventional material would probably be the most likely method of accomplishing this. That would also allow it to be printed in sections (necessary to fit on 99% of the printers out there).

I agree with Nihil that current 3D printing technology is not a good fit for this - except for maybe creating molds/forms... and even then, I think a CNC router 'machining' a 3D mold out of laminated MDF would be faster/easier/cheaper.
For the most part, home 3D printers seem to be best used for creating parts no larger than 8" in any direction. It is more economical for complex and low production numbers vs injection molding.
I think it takes owning one and lots of trial and error to get a feel for what can be printed, what should be printed, and what is currently impossible.
The coolest thing about this technology is designing something in CAD, printing it in a few hours, touching and testing it, and then immediately revising the design and printing version 2. It allows for amazingly rapid development vs other technologies.

Thank you for reply to my query. I would've thought the size of the part created would only be limited by the length of the rails the print head could traverse. They're actually able to 3D print whole houses now!

The problem with printing larger things is that you need to use a larger nozzle to have a reasonable fill rate. You end up losing resolution and accuracy - so the final print will need secondary processes (sanding, machining, etc) and you lose a key benefit of printing in the first place - one process.
There's probably a commercial printer out there that can print a dash in a single piece with reasonable quality, but it won't be cheap. The overlay would still be a separate process.
