Curious if anyone here has any experience with 3d printing functional intake parts, reed valve boxes, reed valve bodies, carburetor mounting flanges, etc.
Bonus points for experience with ethanol/methanol fuels using 3d printed intake parts.
For a few reasons I am attempting to come up with a working solution for 3d printed reed boxes for my application.
3-4 different carbon type filaments have been used in standard FDM style printers, and so far have failed pretty miserably.
Following a thread from a few different manufacturers that are actually selling retail 3d printed intake parts, I have my latest round of test parts back, printed out of Nylon PA11 and Nylon PA12 (expirimenting between the two) printed on an HP MJF machine, the important distinction being that its not a filament deposition technology, but instead a "powder bed fusion" technology.
Pictured below.
The darker "flange" that bolts to the cylinder is Nylon PA11, the lighter reed box that bolts to the flange is Nylon PA12.
Will post back with the results from testing these samples.
