Your shifts seem likely caused by your speed selection, bed slinger printer designs have to move that entire part which has a lot of inertia with a part that uses nearly 1kg of material.

3d-printed Screws, ballbearings, coils, wires and magnets is impressive!

For the bearings, you want to add a shoulder that catches the stationary race, but doesn't touch the moving race. The larger bearing you put in will wear the housing the same way, because it is still rubbing. Add a shoulder that only touches the inner race, and it should last longer.

7:35 you should have printed that the opposite way. it would have taken way less infill to print it on the other side

This is a pretty cool project! I think a thrust bearing might help with bearings getting embedded into the housing.

This is so cool! I've been thinking about printing generative frame arms for so long!

Looking good mate, well done, looking forward to the next video

Good fun! Thanks Michael.😋

buff quadcopter heck yea

as someone who loves my multi day print jobs I would highly recommend z hop or z lift. Some people rebel against it but it helps so much in keeping these sorts of layer shifts from happening .

Awesome video and project!

I just discovered your channel. This is so freaking wonderful. I can't wait for the next video!!! I'm going to go find it now.

Such impressive work altogether, material design, testing, jokes.. 👌🏽

I just found your channel. Couldn’t subscribe fast enough. I can’t wait to catch up on your previous videos. Cheers!!

"Incredible project Michael and you're so young! Congratulations on the project. I'm eagerly looking forward to the next steps and the opportunity to assemble this drone. Thank you for sharing. May the Eternal always protect you. Hazak ubaruch again!"

This is so amazing to me that it's pretty unbelievable that it could be done, and this is done so well

Incredible mate, making 3D printing look so easy is a skill

very cool!!! I would love to try and make something like this!

I've wasted so much of my life looking up the definitions to words I thought I already knew, like "entire", "entirely", and "literally everything". What I discovered will literally, totally, completely blow 100% of your entire mind in it's entirety.

Very impressive, I love it. Can't wait for more

love from vietnam

Brilliant.. Just brilliant !!!

This was my dream back ib the day when I see Mr. Christopher’s video! Ty for sharing

Muy bien! 10 puntos.. necesito mas!!

That looks awesome.

Man, impressive af! And your prints are spectacular. :)

Amazing !

Nice! You can use PLA-LW, this is awesome material for quadcopter or airplane. I use pla-lw for small quad and big airplane

This is incredible!

I love that you even printed the Motor. It's really creative how you tested it and made soup. Genius! As well as the arms and how you edit. Awesome stuff man!

Awesome!

This is so crazy cool! Right up my alley! Subbed!

Very cool!

incredible video and cool project. thanks

Amazing video, best part was the cinematography, great mic, great jokes, and amazing usage of engineering

Amazing.. congratulations 🎉

Great video, awesome project, very well done

This got a sub from me. Super cool, man. Keep up the great work!

Amazing and thank you so much for this

This is a pretty cool project!

It’s hammer time!!!

Awesome and impressive !

Great video, I had a good laugh watching this and it's a very interesting design challenge to make a 3D printed quad :)

Awesome 👏

Delightfully elegant design all around! That center section would be easy to configure for aerially delivered payloads of friendship, spotter cameras etc. The arm design would simplify increasing motor count for large payloads an/or batteries. A dyno like that made by Torque Test Channel to test die grinders could be ideal for your motor tests. The shoulder bolt was a brilliant way to avoid custom machining while getting a shaft more than strong enough for the job.

great quadcopter / this is a cool idea

Brilliant Idea and Engineering mate 👌. A suggestion for another video could be , how to make a drone from sustainable materials. Loved your work!

Waiting for part 2 🤩

Excellent video!

the motor lag is probably a combination of both the higher moment of inertia and the non ferrite core, the latter reaching its magnetic saturation point more easily (thus capping the max torque), maybe you should try to redesign the motor with a non magnetic core and just wrap copper windings embedded in resin around it and veeery close to the magnets, you can also hold the magnets from their extremities to shave this distance even more. design wise I think there is a bit too much material here, the arms are way heavier than they have to be and the main body could loose some weight too 😶 still an extremely interesting project, well done !!

Dude, i'm astonished.

This made me sub good work!

Love your project, so this is just meant as some positive input: 1. You obviously know how to use CAD, split the body and make ie. dovetails in each part that you lock with small screws and heat inserts. This will be as strong, if not stronger, because it’s gives you the opportunity to print parts of the body in different directions to better accept loads. It also make it easier to make the body lighter. 2. Splitting the body gives you faster prototyping, and you optimize your printer time 10 folds, by not printing so large parts and then have something that fails or in need of a reprinting. 3. To take it completely out, buy a 3-5mm of carbon fiber plate and make that as top and bottom and 3D print the rest of the body. 4. Klipper has nothing to do with your layer problems. Lower the speed at the end of the print, you can do this manually or even with g-code in klipper(mainsail/fluidd/ octoprint).The problem is probably just to inertia/weight to your nema17 motor running your bed with almost 1kg of PLA. 5. In Klipper you can increase the current of each motor (printer.cfg). You can crank it up a bit to help the motor for the bed combat the weight with higher torque ( it will run a lot hotter, but many people are doing it, but that’s up to you) 6. I’m not sure how PLA will hold over time when your motors get warm. PLA starts to deform around 60-70 degrees. ( I have had PLA brackets fail around 55 degrees and deform). it’s simple to enclose the Ender 3 with a cardboard box and print in ABS or even easier ABS+. Don’t try PETG, it’s better than PLA, but a lot weaker to heat and grease/ lubricants than ABS. 7. Perhaps redesign the motor core with the use of resin and try to shave of some space between coils and magnets, it’s difficult, but you will see significant changes in the motorcurves. 8. Since you have access to more than one printer, make one an ABS only printer, while you keep the other to print in open air with PLA. Anyway, thanks for sharing, looking forward to your next video.

HAHAHA you beat me to it. Amazing. I might following this up in a couple years with my own version of the motors n such. Thank you for sharing

Awesome, here for it. I was wondering if you'd be willing to try an interesting side project: I used to print these "parametric 18 blade shrouded propellers" that I found on thingiverse, they're very neat and look like a jet turbine. I used them at many scales for power generation experiments but I always wanted to see how they'd perform on a drone. Anyway, thanks again.

Super cool 🎉

I want more! This is so cool

Lool what a brilliant project :D

I didn’t care about the title until you specified the motors, absolutely fascinating idea! Subscribed, can’t wait for more.

for fixing the layer shifts turn up the y axis current a bit and tension the belt if its not tensioned enough (too much have the opposite effect) also i think there is no need for that much infill on the base its better to use less infill and increase the wall line count

Man, this is so cool

Just WOW MAN! Great job! I even can`t imagine how many hours you spent on this....

keep going man you go it :)

I love this guy, he doesn't waste 😘

I've got to subscribe. This is good stuff.

You can speed up those prints and reduce warping by printing with a larger nozzle (like 1.0mm or so). This will allow you to greatly shell parts and rely almost solely on walls for strength. Cool project!

I can totally relate to the frustration with the weight sensor. I used one to build a scale for hay nets and one got destroyed quickly and the new ones had M3.5 (WTF?) holes.

So cool ... I am inspired to try something like this, but probably on a smaller scale!

Really nice video

This guy makes the best videos

@6:15 You lifted the box up a bit. 3 more and you may have been able to carry that 2x4 box.

damn this is getting crazy

Thanks to the KZfaq algorithm for suggesting this channel to me. Great Video C:

Finally someone did this

Not sure if this is at all related to your issue, but I had shifting layer issues on my creality ender3 due to overheating of the controller. The thermals were very bad which caused it to momentarily shutdown and restart, but continue the print with small offset errors. I fixed the problem by improving the thermals (just making the control board open to the air)

The problem with those arms are the extra perimiters generated by removing material. For a 3d print with a certain ammount of outer shells this will add more weight than a sparse infill. Since the outer shell is doing most of the "holding" and the inner material is there to just stop the walls from collapsing you'd be surprised at the low weight savings. You do get a LOT longer print times though. Which you seem to love. 😜

This seems like it would have been an excellent place to use foaming LW-PLA filament. But I barely passed my physics classes in college, so I can't say for sure the pieces would be able to withstand the necessary forces.

For the main body piece, you should use the "tree support" mode in CURA so that you use a lot less material.

You building real badd ass muscle Quadcopter!

I love generative design, I wish more projects used the optimization features. overall very cool project

crazy!!!

very good job

6:48 is that an Esp32 on your test rig? I love the things! So useful for everything.

Very cool! Can you optimize the central section like the struts? These 3d printed motors are really neat! Next we need a 3d printable motor winder.

Its crazy how far technology has come, having a machine that prints other flying machines.

Awesome.

Last night I watched Fast n furious 7... only half as entertaining as your video. THUMB UP³

Plastic Magnets, copper, shafts, electronics are amazing.

MUY BUENO!!

I think the way you are making the videos is for people who just want to be entertained rather than learning something, so I suggest you continue to making videos like a pool full of jelly beans and such

Cool Project Michael! One comment on the generative design piece. it seems like you have inverted the loading direction. I think, the are fixed in an inverted nature to the force direction they are designed for.

Very interesting, Great Vid ,I am realllly not using my printer as often as i should,

Looking forward to the 3d printed flight controller and ESCs.

i love how your test pushed on the arms

We need to get this guy a Bambu lab printer so he can print faster

Damn this is very impressive 👍

This is awesome the number of times people have told me my AR-15 isn't printed because I use like 10% metal pieces drives me crazy. Good to see 3d printing being pushed forward by non gun creators.

Will do(subscribe)cant wait to see the end product 👍💯👍✌️and great job

nice dude

Just something to note, double check the max drone weight & size limit for your state or province. Here in Canada, we have strict laws limiting the drone weight to 250 grams max without a drone license. I would hate to see your video taken down because this looks AWSOME and some great effort has been put in!
