- The @QIDITech X-Plus 3 is really good at printing with PAHT-CF, PA-CF, HIPS and other engineering plastics. Definitely not a PLA machine!
Also toroidal propellers are really fun to put on $45 dollar Amazon drones.

I'm broke, let me pull out a $5k 3d printer
I own the same Printer, it's awesome and costs ≈750$
Lol 😂😂
Don’t get free printer
I feel like every time someone complains about the price of 3D printers, they've never even seen one in their life.
You realize you can get a 3D printer for a few hundred bucks, right? The filament is cheap as hell (Even the most expensive filaments aren't that bad), And after the initial investment there's basically zero upkeep costs.
@@deuslapis5247I wouldn’t say all that, stuff like PEEK and PEKK cost an arm and a leg still.

@@gbyt034which is why he is richer than you
Broke people dont even have a place to sleep.
This manchild is the definition of pampered.
he’s broke, not poor
It looks like you made it quieter but at the same time it looks like it's flying awkwardly.
I suspect it’s due to manufacturing imperfections. AFAIK, 3d printing uses filament and may leave small inaccuracies in the propellers, which have the additive effect of losing some aerodynamics.
Or maybe because it flexes harder than an hp hinge
@@Wilkins325 no its just aerodynamics he got to adjust some stuff on the handling
Probably the printed props are unbalanced, but also many things were changed, but the PID settings on the gyro of the flight controller remained the same and are likely off
PID settings are bad
Normal: Drone noises
Silent: Mosquito and fly noise
😂😂😂😂 still noisy
and its annoying as well@@vincencohan3626
Now nobody will suspect my claymore "mosquito"
blade noise is gone all you hear now is the shitty motors buzzing. put these on a brushless and it will be much quieter
Drone with orange thing sounds broke
Hey it's a step in the direction of a cheap and silent drone, pretty damn cool I'd say
silent drones. hmmmmm..... a privacy nightmare nonetheless 😨
Wait till he learns about phones and social media
@@relaxedandmotivated7817fly high enough and any drone is silent to someone on the ground
@@MrMats0n You can still hear the sound even from half a kilometer away, because it's a high frequency, which our ears are incredibly sensitive to
Still makes noise
Balancing the props should make the sound a lot smoother, less fluttery. Already sounds a lot quieter, and i think balancing is all it really needs. Really cool concept
He never even used them on the drone he bought from Amazon though LMAO
Wow! That difference was amazing! Sounds like maybe just some lubricant and it would be even quieter!!
The noise is from the propeller breaking the air
You have no idea about what you're talking about, do you?
No need for lubricant because the motor's noise is not the biggest thing.
The noise is cause the props are not balanced
@@ToastyProductions. ohh, I’m not too knowledgeable in this stuff but that makes sense
in order to get the most out of them you should also sand them or use some other method to get a good surface finish. it's essential for propeller efficiency.
A solvent vapor treatment could help
Acetone works well with ABS plastic but not sure for what he's using.
@@tibbs3112yep, just don't overdo it xd.
I'm speaking from experience
And balance them
@@tibbs3112he said they're polystyrene in the vid but I don't know how any of this works lol. I was just coming to the comments to see if anybody else thought maybe they needed to be smoother
Makes sense
The blades work well! But that flitter in the sound makes me think there might be some small imperfections in the print, or it might be a result of lacking stability or a combination.
Or it could be neither, I don't know much about drones
The drone didn't have direct drive motors so I had to 3d print gear housings to make it work.. That's where the flittering is coming from.. Would probably be even quieter if it was direct drive
It’s 3d printing a drone frame that’s the issue. Especially hobbyists drones. Creates a lot of gyro noise
I was going to say sounds like something between the motors and frame
@@blake3dcakeor make it belt driven that would make it even quieter
In the video it seems that the arms of the frame are flexing, so that might be a good indicator
shoutout to people calling out the price of the printer that didn’t hear him say he got sent it
Thank you for being one of the first to actually use and show the shapes in use! Awesome work!
Request try out the different drone propellers in different wind speeds and see which is more resistant.
Likely the silent propeller will have greater wind resistance & will use more power to travel & stay afloat
Shorter distance range
“but im broke”
takes out the 3d printer
And he says it was given to him
That's why he is broke
3D printers are not expensive.
@@harrisonmarcum2311this one is
Uhhh, they’re like 150 bucks for something extremely decent
Toroidal blades must be incredibly accurate and balanced beyond the 3d printers capabilities to be what they are truly meant to be
Working on this for my engineering senior capstone project, using a 3 bladed modified design using up less material
The propeller style is used to reduce vibration, drag and to increase thrust and in return they are much more quiet.
It's the bad things like vibration and prop drag that create the most noise. Checks out
107 upvotes on an incorrect answer. its crazy. the trick here is to spread out the sound frequency by adding surface area. this suboptimal print had more drag, more vibration, and less thrust than the originals installed on his drone.( this is why he did weight reduction). even with the imperfections, it was STILL quieter according to human hearing.
now how many likes would i get for the real information?
@@willcal2738don't be sad, here's my like 👍 (I completely igree with your answer btw)
In reality, you believed a bunch of videos from aggregate sites like yahoo/MSN/etc that believed a con artist out of MIT whose original video on these, didn’t even include before & after audio. The fact is that what you’ve been told wasn’t vetted because “journalists” don’t know how to do their jobs anymore & take everything at face value. These don’t do what you claim & those claims generally apply to water & not air, since these were actually designed to reduce drag on boat props to help stop them from getting caught in organic material. If they did half of what’s claimed, no drone manufacturer would be putting the standard props on their machines
Obviously not here, the drone was vibrating so much
I tried them on a powerful 5 inch racing drone and I mean a thrust to weight ratio 13:1. I promise those props are way louder in certain areas of throttle range.
Quieter than stock blades though no?
If they were 3d printed, there is a good chance they aren't gonna be as quit. Currently, 3d printers are really bad for making props of any sort due to the core limitations of how they work.
@@gearhead743 Yep 3D printed just isn’t like injection moulded polycarbonate. I think I gave the wrong impression since I believe the toroidal props I tried were also polycarbonate.
@@CosmicCustodianyea but the sound it makes is disgusting and personally I love the noise of a good racing drone
I think we need more tests with these. How about increasing the amount of blades per propeller? Its a big field for experiments.
MIT or some university already did, TH-camrs just make cheap copies that are kind of not at their level.

If I had time and money I would be doing the same thing!!! Just having fun and building stuff like that!!! Keep it up!!! The word of the day is FUN…. Let’s have more of it!!!
I would be broke if I had that setup too. 😂
Unfortunately I'm broke, so let me go get my $700 3d printer, about $30 worth of filament, and more hours of my life I'll never get back to cut the volume of a $40 amazon drone down and it doesn't fly steady any more
the company sent him the printer
did you miss that in the video? 🤔
That's more like 100$+ in spools
Dude he was sent the 3d printer,he said so.
I own that Printer as well. It's a hidden gem and easily as good as the P1S from Bambu, with around 40% larger build area and even heated chamber!
and then being sponsored and pay nothing and get free stuff
is what you missed
This is so stable with your printed propeller 👍
Keep working on the props I’d like to see how they sound if you can get them balanced
I would argue the second drone would be the exact same in terms of decibels if it was subjected to the same weight
If im not mistaken the sound comes from the ends of the propellor blades so having blades enclosed with a ring also reduces sound
this is exact time I have my X MAX 3 printer
Those orange propellers made the drone very wobbly, look at it closely
True. Perhaps the props weren't balanced properly. The RPMs required seem lower for the Toroid props, so perhaps although wobbly, they're a more efficient design.
Yes it sounds imbalanced.
Too much flex in the crappy 3d printed frame. That's why carbon fibre frames are so popular.
I think also the weight reduction he did messed up with the drone dynamics. The controller probably doesn't account for the changes in weight and the changes to thrust due to the new propellers
"I'm borke"
**Pulls out gigantic 3D printer**
He literally said the company that makes it sent it to him for free. Use your ears.

I’m in love with the garage!
You are a engineer smart I like your drone and it works well.thank you for sharing 👍
Bro just bought a drop shipped drone for like 4x more
Very cool! But looks like the frame needs some reinforcement, it’s wobbles a lot
As part of my engineering capstone project, my team is currently testing different versions of this propeller changing the parameters such as diameter, pitch, and number of blades. My team will cast mold these propellers testing 2 different materials: polyurethane and epoxy resin. We are also using Softwares such as ANSYS to acquire the thrust levels at different rpms as well as acoustic data using ANSYS Sound. Hopefully by the end May of 2024, we will have a fully operational that is less noisy, has high thrust levels and efficient. We are still in the experimental stage, but we plan to measure the thrust at a given rpm, power draw, efficiency, noise levels, and we will test them at different operating conditions.
Sounds so good
Massivly quiter and mostly balanced, well done
The cinematography in this is top-notch.
No, it's actually pretty annoying
Sounds awesome 😎👍
Dalprop with Foxeer has been making these propellers for some time. They are used on 5 inch FPV drones.
Never seen that propeller design before. Interesting.
But I’m broke… pulls out the 3d printer 😂

Good. Keep up the good work.
Sounds beautiful
DJI is looking into it, the problem comes down to replacement, and also they take up more space, and we all know DJI is all about their drones being as foldable as they can be
We solved it in a different way. Our team threw out all of our DJI drones. Anything from a Chinese developer is now blacklisted and rightfully so. But it wasn't because of this issue and it wasn't just because the Dept. of Commerce has them on the infamous entity list.
If you value your future, you'd do the same.
@@janus3555 So you threw out the best drones in the world because you believe a Foil Hat is gonna help you? at least sell them, or come up with a better alternative... oh wait, there isn't one
@@NortOfficial you're either naive in your insistence or nefarious. There's nothing tin-foil hat in approach when dealing with the locusts (CCP Chinese).
No, DJI is not the best in the world. They're one of three of the best in the world. That is likely to change in the future with the current and planned restrictions in place.
@@janus3555 And yet you have not told me an alternative for drones to the private market
@@NortOfficial Skydio (more for commercial use) and Exo are two of about 9.
Our company and even our competition are using those two.
With some states banning full use of DJI and with a federal push to ban it nationally meeting bipartisan agreement, that, plus the restrictions on China coming up in the drone space, this is really the best approach.
Personally, I'm using Exo variants.
Bro said I’m broke then proceeds to buy $10k printer
If you weren't stupid you would of heard him say a company gave it to him🤦🤦
Pulls out a expensive printer THAT HE WAS SENT AS HE SAID HIMSELF
Brilliant 👏
"am broke" pulls out a 3d printer more expensive than my left kidney
Is your right kidney cheaper than your left kidney then? What's your best cash price for both?
What kind of kidney you got that's worth less than $600
@@denverstewart8301 yes my right kidney is cheaper by $20 and $99.99 for both
that's cool! Even if it didn't work, I love the idea of thinking outside the box or limitations placed on us!
Make This in inventor is so hard. Good work
That's awesome! I prefer that new sound over the OG. I might just print some. Thanks, my G.
Killer job!
Pretty cool invention
It sounds like it actually improved the sound!
That’s freaking insane, I never knew that, you learned something new every day I guess.
I wonder if the military tried something with this kind of technology after World War II or during World War II
I like how he made it look like a bomb
What I like about the toroidal propeller concept is it's supposed increased thrust and efficiency.
Maybe try sanding and smoothing the propellers to help it fly smoother
Now it sounds like the ceiling fan on fast
very nice job!
The vid that says before man you avoided those opticals like a pro wow
Its quieter in peak, but the oscillating whine of the quiet propeller is much more annoying than the steady scream of the loud one.
F*ing INCREDIBLE
Aaa this is great, usually the 3d printed propellers make some weird vibrations if you make the frame thicker it’ll kinda help to reduce that, or if you get a drone with brushless motors cause the motors on the cheap drone are coreless with not that much of a thrust
It did look a little unstable tho, like it was gonna crash down to the ground at any second, but I really love that and the propellers
I'd like you to explain how a specific propeller design can tell how much the drone they're installed on costs.
Had you tried building and cylindrical outer frame for the old ones... Hope will reduce sound with much thicker rims.
I kinda get the impression that it's quieter because the blades are spinning slower. Which is okay in my book since it still flies.
Wow that's nice
The flexible frame probably has more effect on the sound dampening than the propellers do. You should try it without changing the frame.
Dope af
Good job
They sent you a printer? Just like that. Very relatable..
“I am broke”
Buys a 250$ drone
Pulls out a 5k 3d printer
Pulls out his 3k gaming laptop
Pulls out the 100 dollar ink to print his wings
the normal one sounds really sharp and shrill, the toroidal ones still make noise, but its a bit softer and more pleasant to the ear as compared to the normal ones
Wow... Huge difference, outdoors it's gotta be quieter, the breeze is louder...
It would be quieter if you balanced them and sanded them smooth
I love my X-Plus 3 printer.
Keep in mind that the layering due to the nature of 3D printing increases the turbulent air, which increases noise levels. A smooth molded piece will make this design much quieter
Those propellers shape seems like it was also help the durability if it bounced against an object.
👏👏👏 great, what a big difference! but now they would have to be balanced and success would come 👍
They’re not that much quieter but the noise is less annoying 👍
Ji ha chaia aisi series
next level
Arms was about to break off
U should incorporate whisps on the top n bottom sides of the prop. U could most definitely deconstruct hawk feathers, and use them to quiet it, and or owl fluff
Awesome
“Everything you see was printed on this printer”
Me seeing the floor, the walls, the desks, a PC,.. 😳😳
Sounds like the key with the messed up wing on Harry Potter.
Me hace dudar de que el vuelo sea real parece que está sobre una cuerda 😅 pero lo replicare para verificar saludos 😊
Heyy, that is actually relatively quieter! 😃😃!!
I have one of those cheap drones and they work well for the price. If you just like messing around it’s better than splurging on a nice one.
I would love to see which is most efficient.
After one sounds like super saiyan
Printer company name sounds like a South Park skit “tank you four cahrring shiddytech how mehhelp yew?”
theres gotta be a way you can balance them so they all are equal weight and distribution, thats the only huge difference with the expensive stuff is the consistency of the parts, cant wait for the next iteration
I don't know that it's quieter, but it's at least a less harsh sound
Just gotta get rid of the squeel is all that's crazy good job
''Im broke''
* Pulls out 3D printer *
What I think it's also that the shape of the blades could probably improve over time with people actually experimenting a lot. Propeller shape is not simple!
However I like that these already have less high pitch whine to them
