Flying a DIY 3D Printed Quadcopter... Will it work? 

Working on the fully 3D printed flight controller now, should be ready soon!

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 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.

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.

As the great engineers said - with a good engine, a stool can fly. In this case with a good battery.

Adding random fans is a form of self-care :) Such a cool project!

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

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 👍

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

Awesome! Congratulations! I love the generative design of the frame, beautiful and functional. Bravo.

after having watched the next 9 minutes and 58 seconds I would like to see FPV and think it could be fun to watch 👍

Such an inspiring video Michael. Keep it up!

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.

Congratulations once again. Incredible project!

Simply awsome job. Your fighting inertia of the motors

woah, this is extremely entertaining and fun to watch. It's the first time i've seen someone be this creative with a Quadcopter.

The 3D print is deliciously amazing! ❤️😍

amazing stuff man!

Great work 🔥🔥

Loved it mate, very cool project!!! You’ve got amazing skill with 3D printers

Great Effort i love this project. by the way congratulation for ur success flight.

3D Printed Torodial Props is perhaps suitable for the next modification

Really impressive work!

I am truly impressed by your CAD design. Nice job

Awesome build bro

Amazing work

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.

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.

This was such a cool project

Those engines are sikkkkk. Most impressive part of your build.

after having watched 18 seconds of this video i can say its great 👍

I love that you picked a Noctua fan, because noise levels are really a huge concern! (yes, I know they can have higher flow rate too)

Making a drone from almost purely from scratch! I love it!

I like the touch of adding an additional fan to a thing that is basically made of fans.

TOTALLY AWESOME IM SO HAPPY IT WORKS!!!!! 🎉🎉🎉🎉🎉🎉🎉🎉

I think , this is probably most interesting and beautiful printed project .

loved these vides michael, well done mate, you have gained a sub 👍

great work.

That monstrosity look Badass🙌

Great video

You got my sub!!! Great job!!!

The figure for a safe landing, and you are amazing

awesome stuff, really!!

Cool quadcopter

great, thanks for sharing 👍

I love this project! I would really like to see how you get on using 3D printed props

I did a double take at 2.5kW... insane

Amazing!

So cool!

Very cool!

Oh for for the love of it!!! Your telling me the 10mm goes missing in the 3d printing hobby too. Dam it!!!!

What is more needed than a fan? Fan with temperature controlled speed! :)

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).

Dude good shit that thing is sweet🔥🔥🔥🔥🔥🔥

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.

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?

Love it

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!

congrats! 😄😄

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.

Dude made his own brushless motors, WOW!

You did it. cxongrats!

Interesting! I'd love to see it with a camera turret or some sort... But FPV is also fine!

Nice video, thank you for sharing it :)

Things have come full circle

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.

i love how beefy the motors look. impressive build!

Это потрясающая работа!!! Вы большой профессионал!!!

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

Pretty impressive.

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 :)

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.

Great work! I'm definitely gonna subcribe to your channel for more! 😁

Love it! Adding the fans seems like asking for trouble though. Fans spin due to air and send power back to controller.

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.

i would like to see more on the motor build great job

Badass!

What a project man! Great! Now a minidrone lol

It worked. It finally worked

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. 😉

since you got so big motors an the rpm has slow response(but probably 'sturdier' torque) , i suggest variable pitch propellers for control

I love putting fans on things 🤣🤣🤣 Okay? Now i love it too 🤣

love your videos micro rectum!!❤

man grait video, i would love to see you try printing and experementing with these new MIT torydal propellers

Ey bitte weiter und mehr Videos auch abgesehen von cupra, du wirkst sehr sympathisch!

This guy just casually says it takes 2.5kw like it's no big deal ... I wish I was making stuff like that

Nice video ❤

Have you considered le asa filament? It has a blowing agent that makes it puff up so it is super light weight and does have impact resistance.

very nice, also to see BUT seems very heavy to me and yet proof has been provided 3D printed and flying hats off! or... respect!

An idea i have is trying the weird new props for quiet flight. The drones that deliver food use em.

Jeeze, I thought I liked to DIY. Hat's off to you.

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 :)

Yeah! Science!

Im really impressed !! ... you wound your own motors.

Fpv for sure. 👌

Hey man awesome job I'm impressed. What KV are these motors ? Secondly, could you swing a larger prop and make the arms longer ?

WOW!

FPV! I want to see you try to Freestyle it! COOL

Yes. Awesome. And fpv.

Cool project! Maybe an update with 3 motors instead of 4 would be more cool!
