A intake manifold I designed for my engine so I can mount a supercharger... Printing it out of Polycarbonate with hopes and dreams as the ender struggles lol.

Using the wrong materials and design in 3D printing airplane parts led to a crash in the U.K.

The stuff im using has a glass trans temp of 140C, if it fails it fails, its a car and ill still be able to break to a stop. Im expirementing if its possible, and its the highest temp filament i could find that was not PEEK. Although why would they ever put a 3d printed part on an airplane, that a recipe for disaster lol

#

The stuff im using needs 280C, 110C bed, and a 70C heated chamber just to print lol

#

highest i can remember is TPI, 420 nozzle 180 bed vaulthah

#

dont think many printers can run it

undone atlas Apr 1, 2026, 8:50 PM

#

Yeah I would not even have a shot to print that

#

Im torturing my poor ender 3 s1 thats not even supposed to be in a heated chamber

#

on the bright side the hotend is rated for it and im using hardened nozzles

#

Rip stepper motors tho they are def degrading lol

#

all metal heatbreak check as well?

#

Had to reprint my y axis mount with PC as i melted the abs one lol

#

Yep, Ive got the sprite full metal and metal gear hotend

#

good, some think they can print the hot ones without it, PTFE melts way lower then they think

#

or just dont know about it

undone atlas Apr 1, 2026, 8:52 PM

#

Bingo!

#

I upgrade the nozzle because it was brass, and its got full metal and ready to rock stock other then nozzle

#

im using a 200Watt 120v PTC heater to get the chamber as hot as i possible can

#

#

#

I also have a intercooler to bring down the IAT, at most it should see is 180f

#

which is 82C

#

I looked at metal sintering, buttt i got quoted 10k... So this is worth a shot haha

#

might be cheaper to get it milled vaulthah

#

just gotta take off some of the filets

undone atlas Apr 1, 2026, 9:00 PM

#

Im not sure if it can be milled, the inner cavity has some odd geometry. Mabye a 5 axis cnc might have a shot

#

but it def would also have to be in two parts for the insides, I have to anyways on my machine so i designed the sides to have bolts and planning on using polyurethane, or high temp epoxy to join and act as a gasket

#

its very expiremental though..

#

This is with the bottom cut so you can see the inside

#

#

#

Fingers crossed it doesnt warp. Not sure if it wont being honest, buttt gotta expirement lol

We shall see how it works. . .

#

N/A for now

Oh now that’s cool. I always love to see car parts. I’d love to do an intake for my truck but the exhaust is too close to the intake

You could design a heatsheild of metal between them

#

Also update, several days and lets call it "Spirited driving" its been holding up very well. I have had 0 issues with it

#

I have not boosted the engine yet.. but soon we shall see
