Aircraft Ducts 3D Printed in Composite Instead of Metal | The Cool Parts Show Ep.68

[@AdditiveManufacturing]

FOR ALL ACCESS MEMBERS: When 3D printed ducts are in full production for future aircraft, the design of 3D printers may need to change. Eaton engineer Si Chen describes the advances she anticipates in our ALL ACCESS EXTRA at www.additivemanufacturing.media/kc/cool-parts/articles/eaton-duct-the-cool-parts-show-all-access?

Mam can we make air duct using wood -pla filament is it possible? And it can be applicable in automobile industry?

[@enkidu9989]

Certainly they could be a lot smaller around the x and y axis.

[@enkidu9989]

I would love to see how they test the piece for it's ability to withstand constant vibration for the expected lifespan of the aircraft and also would like to know how the part is fixed in position so we can speculate on potential stress areas.

Just 12 hours to print that big duct? Damn thats quick. Curious how the layer lines affect the airflow

[@phildand6620]

Depending on their protrusion and peak to peak distance, they may help air flow by creating a layer of air between those peaks and decreasing the frictional forces via air on air rather than sticking more to the surface itself (like a golf ball a bit).

@@phildand6620 would be really interesting to see that comparison made. If that is the case, layer lines would help improve efficiency of ICE cars

My favorite show ❤

[@AqibKhan-xf8vo]

What is price of that part? How much economical benefits?

[@Tasijoe]

Great episode!

In the All Access extra, the printer head is uncensored. Parental discretion is advised.

[@Hteja96]

What about watertightness? One bad layer and you may leak air. Interested to see if there’s a workaround.

[@deepak_nigwal]

she (person from Eaton) said the nano-composites act like sealants while bonding with layers while printing.

Favorite show ❤❤✨✨😁😁👍👍🌹🌹👌👌 thank you much greatful

Eaton is going to have a heck of a time getting PEKK materials like that to print well. They have extremely high contraction during cooling that is further worsened with the high temps needed for these prints. So the issues with these types of parts are going to be significant hoop stress that limits total comparative strength, warping on any flat areas, curl on any sharp corners, and dealing with variable crystallinity for the differential cooling rates during printing. Not even getting to the issue with volumetric air flow and deltaT in the printing enviroment.

Pete's smile is very contagious

[@IkarimTheCreature]

Is this part abrasive flow machine before being put into service, or how are they dealing with the internal smoothness of fdm prints?

[@TheBeddoeFamily]

My dudes..."3D printed in composite instead of metal" This is The Way. Maybe not ALL ways, but a LOT of ways.

FDM parts in commercial aircraft?! I hope these ducts are not safety critical!

[@avenuex3731]

Ok. Look. They are putting chopped up carbon fiber in PET. Not a real big deal.
