How Do We Finish Machine this Large 3D Printed Rocket Part???

[@saram9590]

What is a vortex nozzle?!? For those who find themselves asking this question, I've put together a simplified way of describing what it is and how it functions on a rocket. The vortex nozzle serves as a hybrid method of cooling the rocket's combustion chamber while delivering fuel at the same time, also known as Vortex cooling. Injecting pure oxygen gas into the combustion chamber at a tangent angle creates a swirling motion between the walls of the chamber and blazing combustion that occurs in the center of the part. The layer of oxygen gas actually prevents the fire from touching the combustion chamber walls, enabling the walls to stay cool. Testing vortex cooling is very difficult when you can't physically see what's happening in the combustion chamber. This is where 3D printing is necessary. The original prototype was printed using a clear resin, allowing the testing process to be filmed and studied in slow motion. As you can imagine, this made troubleshooting failures possible. - Community Coordinator Titans of CNC

Great explanation of a super cool (🤨) part. 👍🏼👍🏼

[@ClappedOut]

Great energy, great flow, great sens of humor, and what an awesome part to showoff. Nice video, Trevor!

[@trevorgoforth8963]

Thank you!

These are my favorite type of videos. Hybrid manufacturing!

[@dan3718]

Looks like y'all had fun making this video! The saw probably just left a lot sharper edges lol

[@trevorgoforth8963]

We always have fun! Thanks for watching!

Barry is the best and you can’t change my mind haha

[@barrysetzer]

Hahaha thanks fellas.

[@12erplays39]

Barry's smile and that little hohoho... just amazing to see xD

[@zahirmamdani]

It's beautiful to watch you guys make stuff. Love the sounds of machines at work. Love the fun you guys have. Hate the music you add to videos. These are work videos not movies that you need to make interesting, what you do is already better than movies.

[@daveyt4802]

Great stuff! Aerospace, the wave of the future!

Everytime i watch your videos, i just wanna go back to the industry and work there. But i will never get in such a high end shop :p

[@nederlandsenerd]

You'll miss all the shots you don't take man! If you really want it, just do it!

[@leverman7517]

Start your own shop...

[@daveyt4802]

If you can get an aerospace customer! That's the hard part.

[@leonschumann2361]

it's just so fucking sick what u guys are doing/manufacturing

[@jasondevault5066]

Absolutely amazing

[@robertlafnear9115]

A smaller version of that part might make a great paper weight or coffee table center piece😁... OR.... " you are our winner" item, FYI🤔

[@barrysetzer]

I mean, i love me some chips 😂

[@SJR_Media_Group]

Amazing technology changes how we design, manufacture, and finish parts. Even 1 off parts are now possible. I still remember the days of rapid prototyping. Today prototypes can be made from metal, not plastic.

[@shaniegust1225]

Great video! And you guys are fun to watch. 😉

[@tbonesenior6736]

Great video maybe you can ask the editor to turn the volume down so I don't have where earplugs to watch your video,just on the noisiest bit, thanks

[@openyoureyes3113]

You don’t have volume control At your end. Are you asking them To keep volume consistent?

[@adambunce272]

Im not one to "reply" to much. I usually mind my own but i can't help but think man... If i have to wear anything to watch, witness, whatever, to get this kind of super kool super kick azz content... That's so enjoyable for me, i feel like it's a small price to pay. I say everyone involved including the editor that keeps the sound pure and authentic, u are all appreciated and doin an awesome job and wonderful things for this trade in education alone. Plus what yall do for yalls vendors and customers etc. I love it!! Love this trade!! Keep doin what yall are doin!!

[@OrhallaZander]

Damn! Ya'll made me nerd out! From the Thumbnail, I thought ya'll were gonna make Dalek's from Dr. Who.

Cool video, got a brand new Truprint 2000 too and no fixture to hold the build plate, do you share the CAD file for it ? thank you very much

[@mitofun6967]

[@martylawson1638]

Looks like an ablatively cooled nozzle. Probably make a great misting nozzle on the big mill. Just need in appropriate air/coolant injector plate to bolt on top.

[@vonpredator]

It’s not the size of the chips it’s the quantity. With EDM (wire and sinker) the chips are very small. Therefore you outclass him in quantity by an enormous measure! 🤓

[@barrysetzer]

Oh, and so you two think i cant beat you with QUANTITY of chips? Hmm. Tomorrow, i shall show you 300+ cubic inches of material removal

I found the hand braking of the calibration post interesting as if it were 1/2" 316SS cold rolled rod that would not have been possible.....

[@trevorgoforth8963]

The calibration post is printed with a lattice structure at the bottom making it easy to breakaway from the build plate. You cannot break the solid post by hand.

[@yogeshkumar7402]

Great ,great ,great

[@ToyMarston]

Cooling chambers ?

[@Chriss120]

thanks for mentioning that you will surface grind the base plate. how long can you use the base plate before it gets too thin?

[@leverman7517]

Clean-up on the base could remove as little as 1 or 2 thousand's of an inch, or is even less these days?

[@trevorgoforth8963]

I can't give you a specific number because we haven't fully used a plate yet so we don't know, but it would take quite a few builds before it needs to be replaced, you would be surprised.

[@Chriss120]

@@trevorgoforth8963 thanks for the answer, but please tell us once you have some more data. I wonder if it is something you have to add the cost for to the price of the part, or if you can just suck it up with the profits.

[@thesuperjed1]

Large 316L parts like this will distort the build plate significantly (pulls upwards at the edges due to weld contraction) So material must me removed from both sides of the build plate to ensure the top and bottom faces are flat and parallel, to within approx 0.02mm (0.0008”). The build plate in this video would probably require approx 0.2mm (0.008”) removed from both sides to be flat and parallel again. So 0.4mm (0.016”) total material removed. You can keep using build plates until they’re approx 19mm (3/4”) thick, but it all depends on how large the part being printed is. Large parts equal large build plate distortion and small parts equals smaller distortion. There are many other factors affecting this though, including the metal being printed, layer height, scan strategy etc. Also, a slightly rough surface finish (1.6Ra) is preferable to a fine surface ground finish, so the powder has something to grip to as it is spread during the first few layers. I usually resurface build plates using nothing more than a manual lathe and it works a treat.

[@300SD81]

@@thesuperjed1 Are the build plates a special material, or can you just make them on a lathe from a chunk of scrap plate/bar?

[@martylawson1638]

Can the Trumph shape that calibration bar like an ISO tensile test specimen? Verifying material properties and confirming layer adhesion is important for highly stressed parts.

[@thesuperjed1]

For tensile testing, usually a round bar is printed for vertical tensile specimen’s, and a square bar for horizontal specimens. Then the tensile specimen is machined to final dimensions from this oversized round/square bar. Tensile testing is not usually performed on ‘as printed’ tensile bars, but yes a laser powder bed fusion machine such as the one in this video, could print a somewhat dimensionally accurate vertical tensile specimen, but it wouldn’t normally be done. Hope this answers your question.

[@stewartfamilytravels4328]

Curious why you wouldnt just Wirecut the part off since it can do both the cut and the face at the same time?

Don't you need something to hold the part while sawing it so that it doesn't start "hanging" as it's being cut?

[@petermackay8981]

Could you guys try to shake your camera more and shorten all the .73 second clips down to .49 seconds. I find I'm getting so much time and stability to see all the details that I just get bored. That's sarcasm BTW. Your videos almost make me motion sick and barf. You're doing interesting stuff, how bout you give me more than 27 femptoseconds to figure out what what the frick 'm looking at. And stop filming during an earthquake would ya. Try putting some of your most fabulicious clamps and vices on your cameras. We're not watching a disaster movie.

[@endikallano]

1) you don’t want curl in the flow of the nozzle, decreases performance. You wanna shoot exhaust gases straight out of it 2) the last thing you want to avoid your engine from melting is a large surface area of the nozzle walls. Cool looking, but stupid.

[@JohnSmith-pn2vl]

there are no exhaust gases in this part at all, sherlock....
