3d printed intake

[patrick hubbard]

Has anyone gave any thought into having the pre production intake 3d printed

I have, but haven't the specs or the time. My printer is still under construction. If someone had a 3D design I could do a draft PLA print. Probably by the end of the summer I will be able to reliably print higher temp materials.

That is sweet

It would be more practical to cast it out of aluminum or lower temperature metal, then extrude hone and machine the final finish surfaces, the way they are actually made by car companies (if not plastic junk).

See a CNC billet aluminum intake being made (about $4000):

All manufacturing techniques need further machining, honing, stud placement, etc, but 3d printing is the worst. You could 3d print the molding forms and refinish those to make the mold to make the casting...

More promising just to turbo; you don't even have ECU programming for a Yamaha style intake and its runners anyway.

Well to be truthful once you have a proven 3D design, you can make it out of whatever you desire. Most of the time a 3D printed low temp thermal plastic is made for the loss casting to get the mold. Not to get wrapped up in the how you got there...

I am aware of several thermal plastics that can perform under pressure if the intent is to add boost. I agree metal designs will hold up better.

Also be aware that 3D printing isn't limited to thermal plastics.

A fairly new filament for FFF style printing:

There are caveouts to its usage, but its a metal finished product.

If you wanted metal 3D Printed there are services that can do that too until its a viable desktop solution comes out of prototyping stages.

Thanks for posting these. Now to get some actual dimensions of the intake. I could draft up the upper intake if someone can get some dimensions of the upper intake holes and location of the bolt holes. I can use solidworks or fusion 360 files. I might have an extra upper intake around somewhere.

Can you expand upon what you are seeing is lacking here in the ECU for the intake change?
