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.
Yeah, the combination of
“I printed this faster than normal”
And
“Oh this thing is heavy” really suggests that’s why. Plus the defects were at the top of the print, when most of the mass was deposited.
this is 1000% it. Let the bed slingers die, kill them, if you have to.
Couldnt it be fixed by tightening the belts and increasing the motor current?
@@conorstewart2214 sure, but that's just slapping a bandaid on the actual issue. Eventually you will hit a point where you can't do that and get better results without going slower
Yeah no one tunes their printer settings for weight of bed + 1kg of print.
3d-printed Screws, ballbearings, coils, wires and magnets is impressive!
😅
ikr
Yeah clickbait
@@thenamelessone123 Why, I'll bet he didn't even print the remote handset. Maybe we could all sue Google together!
@@davidbenston4259 interestingly enough, you can inkjet print Logic Circuits. There's academic articles that go back 5 years ago about inkjet printing SRAM Cells for FPGA on flexible substrate (plastic). I'm pretty sure those MSce students finished making a fully functional inkjet printed FPGA. Once you have an FPGA you can do something called Direct Digital Synthesis (DDS) to make a Software Defined Radio. Remaining Logic blocks in the FPGA can be used to Encode and Decode digital data on that radio. Going from a functional Digital Modem to adding on the logical blocks that can become the flight controller is not a large step. With enough time and effort (probably 6 months for someone with the Electrical Engineering skills), a transistor by transistor flight controller could be designed. Producing that flight controller and radio would take seconds to fabricate. My guess is that including DRAM, you're looking at around 10,000-20,000 transistors at best.
While i agree this video was a bit clickbaitish, it's mostly true :)
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.
buff quadcopter heck yea
7:35 you should have printed that the opposite way. it would have taken way less infill to print it on the other side
Yeah, I was looking at that like, "WTF, man, flip it over"
@@gpweaver or at minimum print in 2 parts.... i cant believe a whole roll wasted on support material
I was going to recommend tree supports, but that makes so much more sense. Also take it easy on the infill for parts where weight matters!
Seems like this guy knows what he’s doing…
Was thinking the same thing
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.
This is so amazing to me that it's pretty unbelievable that it could be done, and this is done so well
We just please want the STL files.
@@hendrikjbboss9973 yes:D
This is so cool! I've been thinking about printing generative frame arms for so long!
This is a pretty cool project!
I think a thrust bearing might help with bearings getting embedded into the housing.
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 !!
*bumps* somewhat my thoghts too. tho i would rather stick with the magnetic PLA then with completely nonmagnetic stuff. Or if feasable get some transformer sheet metal, would bear the better results even but is heavy in that size of motor. And yeah the structure of the arms can probably hold waaay to much. you can sure shave off 60% of the material (and reinforce the dovetail section maybe) But yeah i wont moan one bit. The whole project is dope!
all the important stuff that actually makes a motor a motor, copper wire and rare earth METAL magnets
Should be printing with carbon fiber and half the thickness. Easily cut that weight by 50%.
yes, i thought the body was way more robust than it need be, but this allows lots of practice crashing. i bet the weight could be cut in half
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 .
Brilliant.. Just brilliant !!!
We need to get this guy a Bambu lab printer so he can print faster
Such impressive work altogether, material design, testing, jokes.. 👌🏽
Awesome video and project!
Good fun! Thanks Michael.😋
Nice! You can use PLA-LW, this is awesome material for quadcopter or airplane. I use pla-lw for small quad and big airplane
I was going to suggest that. 3 kg for the frame with 3D printed motors doesnt sound like it will work all that well together. Maybe it would be worth considering using carbon fibre rods as reinforcement and then you can reduce the amount of 3D printed parts needed.
Is pla lw squishy. I want to 3d print a lightweight mouse shell but don't know if it will be stuff enough
That might help; though id have to pause at the design requirements first. This centre section seems to be designed as some kind of flying tank; not sure that LW-PLA will have the desired penetration resistance against HEAT rounds?.
@@navidmehdi6 I don’t think it is squishy, more just a lightweight foam. It won’t be as stiff as normal PLA but you can also foam it to different amounts to change its density and stiffness.
@@navidmehdi6 Never 3d print something that will be in constant skin contact. You can't clean between the layers and it will get dirty there. If you really want to do it you need a smoothable filament (PVB/ASA/ABS) or use epoxy resin or something like that to smooth.
Incredible mate, making 3D printing look so easy is a skill
@6:15 You lifted the box up a bit. 3 more and you may have been able to carry that 2x4 box.
It’s only really obvious at the end of that segment, when the box visibly drops a bit.
Very impressive, I love it. Can't wait for more
"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!"
Looking good mate, well done, looking forward to the next video
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!
90% of the motors (by mass) is METAL. 100% of what makes a motor actually spin is made of METAL. This is like dressing a monkey in a fancy suit and teaching it sign language and then call it ENTIRELY 100% human.
@@toolbaggers it's still impressive and I had no idea you could print magnetic PLA
Man, impressive af! And your prints are spectacular. :)
great quadcopter / this is a cool idea
> have bed slinger (worst design)
> switch to klipper
> don't do any mechanical upgrades
> bump up the speed
> get layer shifts
> blame klipper
> have bed slinger AND almost 1 kg of material on it at the end of the print. that's a lot of mass to move around, no wonder it skipped steps.
That looks awesome.
This is so crazy cool! Right up my alley! Subbed!
Amazing !
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.
love from vietnam
Amazing video, best part was the cinematography, great mic, great jokes, and amazing usage of engineering
It’s hammer time!!!
Dude, i'm astonished.
very cool!!! I would love to try and make something like this!
Great video, I had a good laugh watching this and it's a very interesting design challenge to make a 3D printed quad :)
This is incredible!
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. 😜
you can also just make them thinner, same number of walls
Awesome!
This was my dream back ib the day when I see Mr. Christopher’s video! Ty for sharing
Very cool!
I just found your channel. Couldn’t subscribe fast enough. I can’t wait to catch up on your previous videos. Cheers!!
Great video, awesome project, very well done
incredible video and cool project. thanks
Amazing and thank you so much for this
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.
Amazing.. congratulations 🎉
Awesome and impressive !
Muy bien! 10 puntos.. necesito mas!!
This is a pretty cool project!
Awesome 👏
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
often infill is slower than more walls anyway
This made me sub good work!
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.
I love this guy, he doesn't waste 😘
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.
Great comment 👏🏻
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
Waiting for part 2 🤩
This got a sub from me. Super cool, man. Keep up the great work!
Super cool 🎉
Brilliant Idea and Engineering mate 👌.
A suggestion for another video could be , how to make a drone from sustainable materials.
Loved your work!
Excellent video!
Just WOW MAN! Great job! I even can`t imagine how many hours you spent on this....
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.
Lool what a brilliant project :D
I want more! This is so cool
keep going man you go it :)
I didn’t care about the title until you specified the motors, absolutely fascinating idea! Subscribed, can’t wait for more.
Except the entire motor is not 3d printed. The housing of the motor is 3d printed.
damn this is getting crazy
Finally someone did this
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!
Too heavy maybe?
"I used generative design"
creates a huge hunk of a non-optimized center section, complains about the amount of filament used.
Hah :D
I love generative design, I wish more projects used the optimization features.
overall very cool project
More people would use it if it wasn't behind a paywall.
what tool?
Man would be such a big help, what do you use for generative design?
@@kareemahmed5036 Yes I also want to know ;)
Me too, I want to know which app/ cad software u used to do the generative design.
This guy makes the best videos
Man, this is so cool
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
You building real badd ass muscle Quadcopter!
So cool ... I am inspired to try something like this, but probably on a smaller scale!
you need an inkjet printer that can print with polymers using z axis..then you can do this on 0.005mm layer thickness
For the main body piece, you should use the "tree support" mode in CURA so that you use a lot less material.
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!
very good job
"I guess this is what I get for switching to Klipper." Can I get the STLs for your upgraded motor please? Really good video and great work on the quad design!
muito bom video vivendo e aprendendo!!!
crazy!!!
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.
Thanks to the CZcams algorithm for suggesting this channel to me. Great Video C:
Plastic Magnets, copper, shafts, electronics are amazing.
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.
Its crazy how far technology has come, having a machine that prints other flying machines.
Really nice video
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)
MUY BUENO!!
I am probably repeating other comments, but:
1. stress test is wrong - the arm will have not compression, but elongation stress. It should be 180 degress turned to withstand real load direction (with motors)
2. with said above - the arm is much weaker than designed, as in this position the main problem would be - delamination because of print orientation.
3. dovetail is inserted from the wrong side. The only thing which is holding the dovetail in place would be a screw. And friction of plastic over plastic. Dovetail also should be rotated to 180 degrees :) motors pull up, core pulls down - instead of sliding out, the dovetail will lock.
4. Infill of the core seem to be Grid - which can withstand only an extremely *low* side load.. if the core is heavy and motors strong - arms will push the sides inside the core = irregular aeroodynamics with tilted rotors, propeller potentially hit the core and so on.
All of it unrelated actually, because everything is done with 100x strength over actually needed. And because of this overkill, a lot of weight is added and works actually only as the useless load.. If one wants to stick to design - less and different infill (Cubic or Gyroid) , more braces instead of "block structure" - the core could just be a plate with underlying "arms" in the same generative design.
Playing some "bridges construction" games really helps to get the idea of stress propagation ;)
Damn this is very impressive 👍
I love skipping past all the pcbway ads in every damn 3d printing channel.
Very interesting, Great Vid ,I am realllly not using my printer as often as i should,
i love how your test pushed on the arms
Last night I watched Fast n furious 7... only half as entertaining as your video. THUMB UP³
My heart sank when you said "we're gonna have to reprint this"
