3D Printed Vectoring Mechanism
HTML-код
- Опубликовано: 8 июн 2019
- This is a compliant mechanism that is 3D printed as just ONE piece! I tested many materials with varying flexibility, because in order for the motor work it could NOT be too flexible. However, it also have to be flexible enough for a small 9 gram servo to move the pivot. Even though a small brushless motor was used it still overpowered the 3D printed mechanism. The thin plastic bent once the motor produced thrust causing the radio controlled airplane to dive straight into the ground in a spectacular fashion.

I apologise for laughing so much at the maiden flight... i guess that's what happens when you mess with 115% probability scope. ;)
More like that's what will happen if you start it upside down
He must have miscalculated the print infill 😊
Yeah Sorry from my side too but believe me you were looking such a dumb after the plane crash 😂
Got to that point and now I understand :)
Hey Man, a piece of advice that can prevent snapping :
I'm banging my head on this mechanism too. The orientation of the print actually matters on this case, if you print sideways (as oriented on the original stl) the layers will be orthogonal to the stress on the flexed beam, thus being stronger than the layer bonding.
I'm actually printing it right now and I'll give a feedback if you are interested.
Kudos for the work, the plane worked fine for a prototype !!
Fantastic editing, pacing and music! The project was fascinating, but I found myself loving the filmmaking even more :)
Thanks for sharing failure, that's pretty rare these days.
Every single engineering channel (Peter Stripol, Michael Reeves, etc.) shows failure. Especially Michael Reeves.
Huh? Just about every single channel I watch that shows how to's wood working or general making has made it a point to show them failing. Its the "popular" thing to do nowadays.....
@@alekseiterin988 sure, but fellow RC ppl that dont have a professional channel dont.
I agree. I thought this video was entertaining and also I learned something so PROPS to you
I mean... too much work went into it to not post....
Dude it's time for PETG 💪
I also built planes as a young teen and I'm into 3D printing now. I wish I would've had a friend like you back then who's interested in the same stuff. Keep it up!
The crazy RC airplanes, 3d printed drone stuff, and scooter mods, is why I'm here. Glad to see you're back at it again, Simon! Keep up the good work!
Oh my gods, that first takeoff was amazing I laughed so hard... I wonder if two thrust vectors with bigger servos would have worked?
And maybe use a carbon fiber or metal infused filament?
Impressive Build.
Nice design with the vector control👍😀
Thanks for sharing 👍😀
Dude i love this channel and im sad not many people know you and your stuff is awesome
I'm from south Korea
And my favorite RUclips is this one 😍😍😍😍I love you!!!
Just want to say thanks. I don't laugh much these days, but everytime I watch one of your videos, I always get a good laugh. Your sense of humor is great. Appreciate the knowledge and the humor. Keep up the great work.
Yay another cool rc video , keep up the good work
Very cool use of the 2 DOF compliant mechanism!
Keep at it, man. Great video!
Ahhhh! All your videos always make me want to build something from how awesome and motivating your projects are!!
Great that you too was intrigued by the possibilities with compliant mechanisms! Thank you for a good video on trying out using them for something practical. I too watched Veritasium episode with the professor researching compliant mechanisms. And I bought his book. I will use your findings if and when I get around to design something myself! Until then - here's a Kudos from a fellow Swede :).
It's great to see you stretching yourself. In this case, sort of returning to your roots to incorporate 3D printing and advanced technology with the compliant mechanism. This video, more than others, raised several questions for me:
1) Center of Gravity - Do you perform any rudimentary balance testing before concluding construction? I'm thinking nothing more than suspending the airframe using fishing line to determine flight characteristics (i.e. nose-heavy, etc.)
2) Stress Testing - Do you perform any rudimentary stress testing before concluding construction? I'm thinking mounting the thrust vectoring mechanism with motor on an instrumented stand to determine the effects of torque, etc. on the compliant mechanism. Then adding a propeller to test with greater loads. A scale would provide information about power before the first flight.
3) Finite Element Analysis - Rather than printing with many different materials, have you ventured into FEA with Fusion 360? You might be able to rule out a lot of materials to arrive at the best balance between rigidity to resist torque and thrust, and flexibility to provide the desired flight control characteristics.
4) Generative Design - Once you arrive at a straightforward design, Fusion 360 can then produce many variants of "generative" designs. Designs we would never come up with; many that couldn't be produced using conventional fabrication methods, requiring additive (3D printing) and/or subtractive (CNC) manufacturing techniques.
Lastly, have you considered printing with carbon fiber filament? Light and strong, though it might not provide the necessary flexibility and almost certainly would fail (crack) with enough impact.
Loving your videos !!
The work you put in this videos is incredible. Congrats!
Those delta wing planes are super robust and durable. We used to combat them on a cliff side with a road behind it. I crashed out onto the road, and a car drove over it. No harm was done, I relaunched,and continued flying for another hour.
You had me unexpectedly LOLing at the "statistical ratio" of your flight outcome probability... you had me wheeze laughing at the maiden-nose dive. Interesting video. +1 sub. I'll keep an eye out for future videos. Good humor!
also, if you don't mind me saying, I think to have that type of vectoring adapter work, you'd need to print two different types of material. Ridged and flexible sections in the same model (and print), depending on the needs of various points of the structure.
Cool, love to see you succeed with this project!
First, I love seeing this compliant mechanism concept being tested live in a new way. Especially how the various materials flexed or broke under stress.
I remember the same video you referenced about compliant mechanisms and, if I remember correctly, there's a key piece that can explain your material strength problem, which is that this particular thrust vector gimble is made with 3d printed metal for the (as another viewer pointed out) much lower powered ion thrusters used for positioning the satellite.
Now, if I were building a blimp or hybrid dirigible, where the need for constant, fast vector changes and a relatively high thrust vectors isn't a requirement, then it might be an application where this gimble could be useful - in a terrestrial environment at least.
Never lose your humor man. I was laughing a lot during this. Thanks for the laugh
I think we love the failures as much as the successes. Either way, we learn, and are entertained at the same time. Keep the videos coming. They boost our projects in ways you may never know. Well done.
Best sentence: "This one I can't remember, but it worked really well..." :D Very nice. Isn't this a great time where you can make what you love and make great videos about it that you can share? 👍🏻
beautiful - this works perfectly -- keep moving forward !!!
you have fantastic tenasity and.. sense of humor :)
i realy enjoy your video!!
nice work
You are great ! Verry nice video editing.
I always like the touch of humour you're putting in these videos! I like to follow your projects.
Sunday night not completely ruined thanks to your video..... nicely done :)
My gosh, that was such a fun video. Loved it!
Loved it! Awesome editing.
Great video dude. Cheers from Melbourne Australia.
I like the way you analyse the problem.
As always, great video!
I am really starting to see the polish in your videos. You've got great ideas, keep it up!
Thank you for showing us how to create value and share it to anyone in the world.
Awesome idea and design
7:23 when your called down to pick up something that you didn’t even drop
I was thinking you meant 7:15
Mac Swanton you mean 7:25 ?
Awesome video like always keep it up
Great finish!
Haha, so funny. I hope you will be able to continue for a long time. Thanks for sharing!
Love it!!! Ive been waiting for some real life functioinal compliance mechanisms. I saw the video of veritasiun aswell and printed some of their stuff!
I might make one of those out of PETG and reinforce certain parts of it that don't need to flex.
Thank you for sharing and staying active.
Nice project
Keep it up❤️💪👊
Isn't your prop backwards?!
what infill did you use? maybe look into higher infill or thickening the thin parts?
that shape was designed for a specific application from a specific material under n specific load. you have changed the load as well as the material so in part this would mean a change in design is needed?
This video right here. You just got yourself a sub. Awesome video😂😂😂
Great edit :)
You keep it real, I enjoy that about your videos. One way of looking at it, is not failures but how many different ways it won't work.
Cool project and really nice Volvo XC60 you have there 👌🏼
that looked exactly like when one has forgotten to reverse the servo LOL
"we're going to see some oscillation, so I'm looking forward to it"... lol. also trying to solder the connector without holding it down and it sliding off the table. that's some funny stuff. :)
Thumbs Up was pressed the second the wing nose dived on the initial flight.
Listen man i could see your frustration and i feel you man, its just part of the RC hobby but continue to persevere continue to make awesome projects for us because the more you fail the more you learn. :)
I was really hoping you'd make a video on these mechanisms after watching Veritasium's video. You didn't disappoint!
your doing great work ,never give up just keep on trying
dude when the plane went straight to the ground, i couldn't breath i was laughing so hard, thanks.
nice proyect! keep it up!
FT Versa wing is probably the best platform for doing this experiment on.
I've built and flown several of them and they are very forgiving.
7m1s... this is the best launch ever :D besides of very good video btw. i love this sense of humor!
These are the videos I subscribed for and I want MORE
Beautiful job, dude! 😃
As soon as I can I'm going to build a wing like that. Maybe with iNav, but definitely with FPV! 😃
Excellent videos bro
Man, awesome project Dude 😎👍 I was thinking of designing the mechanism for my current rear mounted parkjet designs. The Freewing SU-35 gave huge inspiration for its simplicity and strength.
Funny video insertions btw 😄 Welldone!
Nice creality printer and enclosure!
Great Vid!
As always, thanks for showing the fails, they are as educational, if not more, than the successes. I would be curious to see this on a stationary rig with the motor and prop so you can film it and see how the different filaments and sizes react. Nylon feels like such a good fit for this because it is so compliant, but as you stated, maybe TOO compliant.
Dude, so cool to see the RCPowers F-18!
thanks. That was pretty cool.
I love Your Videos
you are the best
Snäll och duktig👍👍
Sei un grande!
Wich 3d printer would you say is the best(i am looking for a new better 3d printe with a huge print room
Your 2011 plane was great
What creality printer did you have in the box? And do you recommend it? I had bought my first 3d printer last year because of your recommendation (it is cr-10). And now I look for a new one. I really would like to have auto levelling bed. I am finking about new tarantula pro or tevo flash or something else. Can you please help me?
Flexibility is also a factor of the cross section of the flexing member, so you might want to try nylon again, but with thicker flexible arms... The concept is very attractive.
Have you tried petg? It would probably work very well for this.
I came to the comments to say this.
can you try using the 2 servos not in that fancy mount but instead in something more basic as a 2 axis "gimbal" like the ones for pan tilt fpv?
Good luck brother, keep spirit!!!
very interesting topic ! go on !
You need an engine test stand on your bench to more closely study material compliance vs thrust. Try some reinforced nylons or polycarbonates.
It's a motor, sorry but it was bugging me
@@calebcrawford8887 The nomenclature is still valid
That is an excellent idea. This would also let him quantify exactly what he had to do to make it work.
@@calebcrawford8887 Maybe learn how to let the small things slide? The internet is already full with people like you
He said he used “pc” (polycarbonate)
Most brilliant idea
Eyyyy.. saw that same video about complient mechanisms, was so hoping someone would do something with them :D
really cool dude
NICE CATCH!
You are the best. it was an awesome
Excelente vídeo! Adoro esse canal. gostei de ver o mapa do Brasil na parede :)
This is going to be great
Try PC carbon fiber, I've been using it for mounts and it's pretty good for robustness and stiffness. Less flexible than regular pc but not quite as stiff as pla.
hey, just wanted to ask where and how did you learn your electric skills? i realy want to go in this world but dont know where to start
How can you still put your props upside down
Legend has it he is still working on this project 😂😂
for the thing to be more rigid - you can print stiffener stripes in some places, not necessarily scale and make bulk the whole thing, just to pay attention to flex nodes
Wow! Your first ever failure, and we got to witness it! 😂
Great video, great channel! I love flying and rc aircraft, I'm looking forward to seeing more of your videos! Great job!
Is there any Varitassiam fan?
can you share the stl/.prt file of the mechanism
