- 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.

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
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
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
@@samholdsworth420 he did? he stripped it down to reduce the weight so it doesn't look the same but it is.
@@samholdsworth420💀
Agreed. I wonder if he used random seam position. That should definitely help with the balance.

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
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
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
shoutout to people calling out the price of the printer that didn’t hear him say he got sent it
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
“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
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
Thank you for being one of the first to actually use and show the shapes in use! Awesome work!
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!!!
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
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
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
I would be broke if I had that setup too. 😂

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.

What I like about the toroidal propeller concept is it's supposed increased thrust and efficiency.
I would argue the second drone would be the exact same in terms of decibels if it was subjected to the same weight
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
Bro just bought a drop shipped drone for like 4x more
You have to 3d print it in a way where u can sand down the blades to a perfect microscopic edge. The uneven ridges cause the air to actually make more noise.
Massivly quiter and mostly balanced, well done
The cinematography in this is top-notch.
No, it's actually pretty annoying
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.
Good thing I was lurking at 4 am this def was the last video I’ll watch ima make this wing propeller style asap asf
I love it wen the plastic covers come off stuff and all u see is the main frame and wires like dam kinda more scary looking 😂
"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
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.
Amazing how every time a youtuber gets something for free, it's always the best thing ever.
Nice try, but I'll watch genuine youtubers.
“Everything you see was printed on this printer”
Me seeing the floor, the walls, the desks, a PC,.. 😳😳
that's cool! Even if it didn't work, I love the idea of thinking outside the box or limitations placed on us!
This is so stable with your printed propeller 👍
The flexible frame probably has more effect on the sound dampening than the propellers do. You should try it without changing the frame.
Dalprop with Foxeer has been making these propellers for some time. They are used on 5 inch FPV drones.
Pulls out a expensive printer THAT HE WAS SENT AS HE SAID HIMSELF
Wow... Huge difference, outdoors it's gotta be quieter, the breeze is louder...
That's awesome! I prefer that new sound over the OG. I might just print some. Thanks, my G.
They sent you a printer? Just like that. Very relatable..
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
Its quieter in peak, but the oscillating whine of the quiet propeller is much more annoying than the steady scream of the loud one.
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.
this is exact time I have my X MAX 3 printer
I wish people would understand how good they are doing... this guy's not broke
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.
Besides the hilarity of “I’m broke, so I’m modifying a $40 drone with my $5000 printer,” that’s pretty impressive. Completely cuts out the buzzing noise. Very cool
I'd like you to explain how a specific propeller design can tell how much the drone they're installed on costs.
Make This in inventor is so hard. Good work
Personally I think the regular propeller werent necessarily quieter but the sound was less invasive because it wasn't choppy like with the toroidal
You are a engineer smart I like your drone and it works well.thank you for sharing 👍
The vid that says before man you avoided those opticals like a pro wow
"I'm broke", *pulls out a full 3D printer*
Yeah, things are not adding up
Idk why people keep pushing these. The data is in. They’re louder, less powerful and less durable. Even with injection moulded ones. The MIT “paper” was misleading as they didn’t show thrust normalised data for regular prop vs toroidal.
Reason why it's flying a bit erratically is because it's 3d printed. It's not a smooth surface so it'll create drag for the propellers and making it endure uneven forces. Either that or igs not slotted in properly.
Toroidals aren't just for a more quite propeller, but efficient ones as reducing the noise reduces drag so it requires less energy to make up for it.
Did everyone’s ears just stop hearing when he said “shoutout to qiditech for sending me this printer”?
The new version is holding back tears.
"I'm broke. Also, this is my state of the art 3D Printer" 😂
I like how he made it look like a bomb
They’re not that much quieter but the noise is less annoying 👍
I’m in love with the garage!
Those propellers shape seems like it was also help the durability if it bounced against an object.
Maybe try sanding and smoothing the propellers to help it fly smoother
It sounds like it actually improved the sound!
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
I love my X-Plus 3 printer.
Impressive sound reduction, especially because most of what it seems like your hearing is the bearings screaming for mercy.
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
Nice, but if you look closely at the footage, you will notice that your drone frame is shaking a lot because of how thin it is. This might explain why it sounds a bit oscillating
"Unfortunately Im Broke"
The 5k 3D Printer: 👁️👄👁️
Never seen a single official sold drone with these props lol
Toroidal is better for water applications,
Back when air flight was being researched a lot of people were treating the air like water,and the propellers they used were ships propellers.
These were inadequate. The wright brothers applied bicycle balance to airflight and realized that they needed a different propeller from what others were using, so the ended up with the much thinner wooden blades. Worked out well enough.
What people are doing here is taking a step back.
This guy: "I'm broke."
Also this guy: Casually pulls out $12,000 worth of equipment and materials gifted to him.
I wouldn't say they reduce the noise but they take away the annoying high pitch.. so that's a plus
Now it sounds like the ceiling fan on fast
Keep working on the props I’d like to see how they sound if you can get them balanced
Frame flexing so much, but weight. Insane 🎉
I should print some. People who know me would just be like "now he's even found a round and chubby propeller ffs 🤦♂️ 🤦♀️ " 😅😅😅
3d printing stuff on an expensive printer because you're broke is the epitome of being an engineering student, i was the same way😂😂
Sounds like the key with the messed up wing on Harry Potter.
Sounds so good
Better for non-vertical propulsion; specifically in water
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
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
Always remember that noise is power that is wasted.
An absolutely perfect prop will make zero noise, but no one has come up with that airfoil design yet.
I bet if you ran a lifting comparison that the new "8" prop design will lift an additional 10% more than the stock prop.
It's still a bit loud, but by the way it sounds it seems to be turbulence caused by a rough surface. It'd would probably make it more efficient, and less noisy to print with a higher resolution or whatever it's called. I don't have a 3d printer.
Edit: I saw someone say unbalanced props, that makes sense. Idk why I instantly thought it was drag tbh.
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
Most of the noise from cheap drones is the gears between the props and motors screaming for mercy
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
Good. Keep up the good work.
“But unfortunately I’m broke” relatleable
You need to then use motors that are quiet. You will also need to play with the shape and texture of your props to achieve the quietness you're looking for.
It would be quieter if you balanced them and sanded them smooth
Only thing I hear is the motor squeaking tbh... that's a win in my books
