Well .... yet another new development.

I'm sure that many of you are familiar with the 3D printing process.

I was contacted by a foundry supply company. After a bit of chatting he suggested that I create the manifold in 3D CAD software and have them 3D print it in wax, ready for casting.  

The process even takes into consideration the shrinkage of the particular metal you are pouring. I believe Aluminum is 1.3% (or there about.) 

I was already modeling this in 3D with Rhino but I had my CNC hat on, not my Investment Casting hat. I just could not imagine how a CNC could handle this (plus that would be very expensive.) 

Anyway, if this does work out, once I have a working prototype, (and if it is cost effective) I can start cranking these out at will. 

I'll be moving on to the air-box (cool side intake) once this is done.
