I think you should reprint it all in PETG, and I think your wall thickness was 4mm, make it 3mm. Than make it all thinner, you might be able to cut down all the plastic weight by 50%. amazing job by the way, I love it
PET-G has a higher density than PLA. Nylon probably is a better material for such a project. It's less rigid but more resistant to snaping. Or maybe Nylon with carbonfiber
Arguably, having a somewhat fragile retainer for the props can be a good thing. On impact, something must give, and personally, I'd prefer to make the engine's rotational force eat a small 3d printed part rather than smash the daylights out of a much more spendy prop. I'd probably say, if it's strong enough to transfer normal levels of torque, it's dimensioned correctly.
One of the benefits if he were to print the retainer out of PETG is that it tends to fail catastrophically with a repeatable amount of force rather than slowly and unexpectedly. Makes it useful for printing predictable mechanical fuses.
the thing is that you should make that easy-to-broken parts also easy to replace. It would be nice to add an easy to replace stress raiser for the arms support.
@@gravymuncher6771 If I had a resin printer I could do that. If I had a 3-axis milling machine I could do a lot more. Point is, resin printers are not a standard household appliance. And I still think the blades would suck.
@@Willy_Tepes worth a try, if you haven't seen major hardware as he prints and test fans, though its more for pc cooling benchmarking, but I think it shows that 3d printed propellers are sufficient enough
@@tyredrunner The issue is layer height and print direction, and how this affects surface finish. On a propeller this looks like wood grain and is not good for aerodynamics.
I personally have been using on shape for over 5 years now for simple CAD work and it's been amazing! It's also completely free, as long as you post your models publicly. I've compared it to other CAD programs like solidworks, fusion, 360, etc, and it holds up every time. Me and my engineering co-worker design things all the time on it, and are both able to access the file at the same time and see changes happen in real time. It's definitely my number one go to CAD program. Awesome build by the way 👍
TinkerCAD is a slimmed down online version of AutoCAD and has most of the features anyone could need, and they don't require you to post your design for free.
PLA Pro is strong and has a matte finish. Also I'd recommend grabbing a bottle of Weld-on 4 and some pipettes. You can literally melt broken pieces back together without heat and make nearly seamless repairs to PLA projects with about 80% of its original strength after it cures.
Dude you are awesome, this is so impressive! I've always wanted to get in to stuff like this but don't know where to start so its really cool seeing a guy I can relate to getting out there and doing it
Finally watched this! Fantastic video, love your projects! All I can think about is how much weight you could cut just by drilling out some of the extra plastic.
Very cool project. I subbed to follow it. The fact that you made the engines is the most impressive part to me. These would be my suggestions based on printing... let's say load bearing parts: Use PLA+/PLA Pro without any further additives like silk or glow-in-the-dark. More walls = more stronger (usually). Use an infill style that gives good strength in all directions rather than a plane grid or similar. I hope to see you develop this drone further.
Congrats for making this heavy thing fly so nicely. 👍 You could try printing different blade shapes and configurations. I've seen number of people claim they have great success with toroidal propellers. 💙 the colour scheme (and the quick release wings).
Consider switching to using ASA as your material. It has a roughly 20% smaller density which could lower the overall weight of your quad and allow for greater flight times. ASA is also UV resistant so when you fly it outside it will be able to handle the temps and UV radiation better than PLA and won't approach the glass transition stage during flight, which needless to say, would be catastrophic. You could also potentially use foaming ASA or foaming PLA for the arms and main body if you were to provide it additional stiffness by inserting smaller diameter carbon fiber rods (this is the approach I am using on my 3D printed robot dog to reduce mass/inertia). PLA ~ 1.25 (g/cm^3) ASA ~ 1.07 (g/cm^3) LW ASA ~ 0.47 (g/cm^3) @ max foaming So if you changed to using the LW ASA at a more moderate foaming of around 0.7 (g/cm^3) you could have a roughly 45% weight reduction while gaining UV stability, greater operating temperatures, and longer flight times. Just some thoughts! Great work so far! Absolutely loving this project
That’s very cool. I’d like to see a similar project but with weight reduction like off the shelf motors and electronics, more of a 3DP race drone with fpv.
Great project! Intuitively, it feels like raising the PID $I$ gain would solve the drifting issue without needing to hard-code in the ESC or FC that a motor produces less thrust. I'd be curious to see if this idea actually works.
How about using Polylight Lightweight PLA for printing? BTW the stories about PLA's biodegradability are exaggerated as 5 year environmental test has showed very little change in structural degradation. Only the colour faded.
I would love to see how this runs with toroidal propellers. This is such a cool project, my boys and I are going to build one. Thanks for sharing your projects with the world.
Really cool! I love your approach to experimentation and learning. I'd be really interested to learn about generative design and what tools to use for it. Did you do this with onshape?
I think he did that in the generative workbench in fusion, if you're a student you get unlimited free cloud credits, which is really meaningful since normally each generative study is like 30 bucks afaik
Oh boy, once it is flying very well, I can see you frantically and obsessively cutting the weight of the drone in every way possible. Just like we FPV kwad hobbyists do :)
Brilliant results. Obviously, it have to become lighter, twice lighter. A lot of exhausting CAD work to reimagine it for remove half of plastic. I, personally, prefer ABS for such task. With nozzle up from 0.8 and +/- 250°C it become strong like injection molded. Nylon-X stronger, but heavy.
Cool project, it reminds me of my journey building quads 15 years ago. :) I'd ditch the PLA and use PETG or even ABS (since you have a Bamboo Lab printer). You can also 3D print the props, but I doubt you'll get better results. There are some new cool designs for low-noise props you could try. Good luck.
Please, please do some dyno-tests for your motors, like Christoph Laimer did !!! I have great interest on how far results deviate from builder to builder, efficiency-wise...
rule of thumb for a freestyle/racing fpv drone is 20% weight for motors, 40% weight for battery, 20 % for frame and electronics and 20% weight for the action camera (racing drone don't get the action camera so they are lighter and faster)... so my first idea would be to make much lighter motors. also you can swap your ESC to make sure it's your 4th motor that is weaker, that is if you didn't use the same esc for all four motors on your thrust bench test. I am impressed by all the hard work you did for this video... I typically assemble my drones in 1 to 3 hours, but it looks like you spent at least 100 hours on this :) I must say your result is much prettier to look at. Also 3D printed frames introduce a lot of vibrations making tuning much much harder than using lighter stiffer carbon. It's also way more fragile. I guess you will need to find a balance to use more carbon for better results while still finding a way to 3d print some parts to keep your sponsor happy.
With bigger batteries it should be programmable, so it can be used as an automatic leaf blower, or why not make it accelerate the melting of snow during "warm" spring days. It looked like it already needs to create a massive airflow just to stay airborne with even more mass from bigger batteries it will be even more.
I know how enticing it is to print those prop hubs on their flats, it means you will have no supports to cut away. If you print those prop hubs like the wheels of a car on your print bed, they will be stronger because the layer lines will build in strength. Your shell is most of your strength in any print, weakest In between the slices. Printing the prop hubs on their side will make the fingers that reach around the propellers stronger
Making the motors too. That's cool. No where near as good as what you can buy but imagine being able to make even better parts at home. That would be crazy. You'll always have to buy the bearings though.
Couldn't find the "Subcribe" Button. I did find the "Subscribe" one and clicked it though. On a serious note, excellent videos. Thank you so much for sharing.
How amazing turned this project out :D It would be amazing if you add FPV functionality with OSD information. Maybe you could also build a smaller drone version with FPV functionality that could land and load on top of the larger drone. Also you could made your own torodial props :)
I know almost nothing about drones, but it seems like you should have some sort of feedback system that makes sure all the motors are rotating at the proper rpm.
What you should do. Use a combination of carbon fiber and 3d printed parts. You can 3d print the body and motor mounts and use CF tubes for the arms. use PETG CF for stifness
If you can print in ABS, that would probably be the best material for this project. ABS is one of the least dense materials available for 3d printing, and has a good balance of rigidity, toughness, and heat resistance. ABS+ from esun or Sparta3D (my personal fav) makes printing large parts in ABS with minimal warping MUCH easier.
Wild that you couldn't find two blade props when just a few years ago there were hundreds of options available for quad builders. I guess it's a lot less common to build big quads anymore.
If you have the X1Carbon you could print the parts in nylon carbon, would be lighter but more expansive. There is also something called light PLA but I think it would be more fragile. Great video thank you.
As a "demostrator" for a full 3d printed drone you should go on that direction whith 3d printed blades. Imagine the global interest for printing a full drone on remote places like Mars. As ever a militar application will be found on that.
First at all. Amazing job. Should feel proud of yourself. A small suggestion. You should try to print a propellers with the toroidal shape. They seem more efficient. And some legs with springs will make the landing smoother. Take care. Great job one more time
Print orientation influences the strength of the print. And wow, that even looks heavy. The key to engineering is to use the correct material for the intended purpose. This could in fact be stronger with a simple shell construction and 5-10% infill. The outer shell is what provides most of the strength. You can achieve 3 to 1 or even 4 to 1 trust to weight ratio with better design.
I would guess you could scale this up probably by double (including prop size but maybe not double) those motors must have some serious torque that might be underutilized even with 3 blades. Awesome project thanks! I've been following the motor project since it's first upload and have been anticipating this project ever since!
Working on the fully 3D printed flight controller now, should be ready soon!
just ashamed for the rest of humanity that nobody else has yet picked up on that.
How much all this setup including 3d printer, instruments to check thrust costs?
I think you should reprint it all in PETG, and I think your wall thickness was 4mm, make it 3mm. Than make it all thinner, you might be able to cut down all the plastic weight by 50%. amazing job by the way, I love it
i agree, but with how massive the print is i think we'll only be seeing that a few months down the road in a V2 that has many more upgrades
Maybe reprint in HIPS. That stuff is less dense.
PET-G has a higher density than PLA. Nylon probably is a better material for such a project. It's less rigid but more resistant to snaping. Or maybe Nylon with carbonfiber
@@blazej135 Yes, nylon is the way to go, ideally with CF content.

True, as long as it really doesn’t fail in flight at some point and cause a much more catastrophic crash.

I was like pfft whatever i 3d print frames too, then i saw it was the ENTIRE quad, motors and all. bro this is incredible! great job.
I still think it's crazy that the motor cores are 3d printed as well.
Also definitely print blades, it makes much more sense for the project
Try to print blades and you will understand why no one does it.
@@Willy_Tepesa resin printer could easily print the blades
@@gravymuncher6771 If I had a resin printer I could do that. If I had a 3-axis milling machine I could do a lot more. Point is, resin printers are not a standard household appliance.

Adding random fans is a form of self-care :) Such a cool project!
after having watched the next 9 minutes and 58 seconds I would like to see FPV and think it could be fun to watch 👍
As the great engineers said - with a good engine, a stool can fly.
In this case with a good battery.
The motors are the engines.
@@MysteryD : Without a good battery, a motor (engine) is a paperweight.
let me introduce you to FliteTest
@@PiefacePete46 without a tank of gas, a car engine (motor) is a paperweight.

Love it! Adding the fans seems like asking for trouble though. Fans spin due to air and send power back to controller.
I was just thinking that might throw it off
Simply awsome job. Your fighting inertia of the motors

Def toroidal props would be an epic video! I subbed just to see if he does this.
I like the touch of adding an additional fan to a thing that is basically made of fans.
3D Printed Torodial Props is perhaps suitable for the next modification
after having watched 18 seconds of this video i can say its great 👍
since you got so big motors an the rpm has slow response(but probably 'sturdier' torque) , i suggest variable pitch propellers for control
I think , this is probably most interesting and beautiful printed project .

What is more needed than a fan? Fan with temperature controlled speed! :)
An idea i have is trying the weird new props for quiet flight. The drones that deliver food use em.
I would love to see how this runs with toroidal propellers.
This is such a cool project, my boys and I are going to build one. Thanks for sharing your projects with the world.

Fantastic, of course!
At 5:03... This irrefutably confirms my hypothesis that the degree of control is the inverse of the pilot's torso angle. 😉
The 3D print is deliciously amazing! ❤️😍

seems very heavy to me
and yet
proof has been provided 3D printed and flying
hats off! or... respect!
Things have come full circle
Great work 🔥🔥
you should print some toroidal props for this thing, would totally fit with the diyness and aesthetic of the frame
Not sure if you know, maybe try printing the motor's stator core which has iron in the filament, makes it more efficient.

I think that the motor may have low power factor and low efficiency, hence low power density.
That low efficiency makes system bigger and heavy.
Looking on the bright side (weight-wise), you could have made an underwater ROV had you gone for DIY batteries as well :D
Imagine some boss at DJI said:"Nice, and now let's make it 249gr". Great vid man!
I love putting fans on things 🤣🤣🤣 Okay? Now i love it too 🤣
Glad to know I'm not the only lunatic constantly cooling unnecessary stuff with tiny fans
Yeah! Science!
Wild that you couldn't find two blade props when just a few years ago there were hundreds of options available for quad builders. I guess it's a lot less common to build big quads anymore.
Jeeze, I thought I liked to DIY. Hat's off to you.
For longer battery try useing Lith-ion way heavier so youll have to revise some of the thickness in some places its a trade off
Love it

I wouldn't worry about your caps for holding the propeller, I'd rather break a cap, then break a blade, when you do hit something, tree or ground. 👌
In Quad We Thrust 🙏
To those who care, hello and have a good day! 👋❤
And that little flight controller, PCB, ever get released anywhere? I'd like to see it more than anything else out of this project.
