A HUGE 3D Printed Brushless Motor??? How Much Thrust Can It Make?

Hope you guys enjoyed the video! This thing was really fun to make and test. A bit scary too. Nevertheless, it was a cool project, and I would love to do more with the motor in the future. Let me know if you have any ideas.

Spending time making cool swirl? Worth it! 10/10

Make a quadcopter with small 4 bldc 3d printed motors that would be amazing like this video. 👍

Super cool build!

I'd be tempted to find a wire mesh sleeve or something that fits around the entire motor housing just to keep any larger chunks in place if it grenades itself. That thing is terrifying at speed

I'd be really interested to see comparisons between magneti- and non-magnetic filament.

That was a really cool video! Very curious to see how reliable this motor is. Be really cool to see this on a drone. Kind of crazy how much thrust a piece of 3d printed plastic can really produce

I've been doing torture tests since getting my printer recently and have found thin stainless steel mesh goes a long way you could also put a few bands towards the center of the housing to help keep your walls from buckling like you see on water towers

I'm surprised it was balanced so well. Knowing the properties of PLA, you should not run it under severe loads that generate heat. Other then that well done and getting the windings correct at the first shot.

Man that was really awesome and i know how hard is to wind the copper and it's perfect 👍

Impressive and scary at the same time!
Great video, with graphs and all 👍👍😍
Thanks for sharing your experiences with all of us :-)

My eyes were glued to the layer lines the whole time on that last test lol! I'd for sure be a good distance away if I was there but it seemed to hold up great!

Really nice. It would be interesting to see what kind of rc vehicle you could use it in!

whoa, the motor mount is looking sketchy :D and the vibrations close after start are scary, but hey it worked haha. Nice. I tried to print things that spin only once. You can guess how it ended up.

That's impressive! I may try to print and make one of these.

that magnetic filament idea was genius, cool video!

Hello Michael i had a couple ideas for possible improvements, there is a couple ways i think this could be be helped. I would recomend trying to get it balanced even if its statically. IDk where you are but it would be fun to put this on our dynamic balance machine and see how much it is out. it being round its probably close but i wonder if the infil has biased this to a certain area. my ideas off the top of head would be to put the printed parts into a jar and pack it tightly with kinetic sand. then spin it up to around 900 rpm or so inside of a oven to aneal it while rotating. a cheap air drill could probably be used if its metal to workk ouut something that can take the heat. i se you have printed it with the layer lines xially around the body of the motor, i would like to see if some thing metal mesh could be installed on the outside of the motor body tieing the layer/grain structure together better. eitehr heat set it in or use some UV resin and instal it and dip it in resin and agin spin it during the cure. also i feel like you should look into getting some statorade its a ferro fluid that helps disipate heat. probably rambling also sorry for the spelling and grammer its not my strong point. great project and video tho dude cheers

Seems quite viable for a quadcopter. I think it may be a good idea to put a few layers of fiberglass around the outer motor to hold it together, and do some dynamic balancing to keep the vibrations to a dull roar.

Sounds like a real plane and it's great

To strengthen it and prevent its expanding and exploding you could use hose clams on the outside, use 2 and put the bolt assembly on opposite side with each one to keep it in balance. Also a general case balancing would be good too. Maybe also print in nylon.

Now you gotta build a VTOL
I may be a little biased…
