I ended up needing to reprint one section. Thankfully I realized right away that the prints shrink in the z axis by 0.5%. It’s a small amount but it would add up to 2mm across the manifold.
Next up is bonding it together and then finishing and painting it. The intercooler ‘cartridge’ is all designed and now I need to order the 3D printed aluminum parts.
I’m a little worried about the size of the Intercooler cores. They just feel small but they should be good for 500hp (~150hp more than I’ll run). I’ll only really know how they perform when the car is on the road…

This is really super cool, that you designed and 3D printed your own intake manifold at home! This was unthinkable just a few years ago when Stratasys kept the industry locked up with their patents.
Which PPA did you end up using, and how are you going to seal it up? Is the nylon glue going to be enough or did you design the interlocking pieces to use some form of gaskets?
Following closely as you are blazing this trail, as a fellow printing nerd.
