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 :)
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
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.
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
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!
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.
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 .
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.
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
Such impressive work altogether, material design, testing, jokes.. 👌🏽
"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!"
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.
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.
Man, impressive af! And your prints are spectacular. :)
Looking good mate, well done, looking forward to the next video
Amazing video, best part was the cinematography, great mic, great jokes, and amazing usage of engineering
Very impressive, I love it. Can't wait for more
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.
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
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
love from vietnam
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?
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 👏🏻
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.
Brilliant Idea and Engineering mate 👌.
A suggestion for another video could be , how to make a drone from sustainable materials.
Loved your work!
This was my dream back ib the day when I see Mr. Christopher’s video! Ty for sharing
For the main body piece, you should use the "tree support" mode in CURA so that you use a lot less material.
Amazing and thank you so much for this
That looks awesome.
Just WOW MAN! Great job! I even can`t imagine how many hours you spent on this....
Waiting for part 2 🤩
Amazing.. congratulations 🎉
This is incredible!
Muy bien! 10 puntos.. necesito mas!!
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
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.
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.
Good fun! Thanks Michael.😋
Great video, awesome project, very well done
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)
Did you stress test the armature in the wrong direction? Great project BTW, super cool.😎
@Cool Cat : Yes, but at least he knows it should survive a heavy landing! 😉
That's the comment I was looking for.
was looking for a simlar comment AFTER i made mine haha.. what about how it was disigned? the ai probale thinks theres going to be a load so it made it that way.. what if it were hanging? what would it look like then
maybe he's flying it upside down🤣🤣
@@eowen-to1oj when you do the generative modeling you tell the program where the forces are and how strong. In this case it's fixed at the dovetail and the expected load at the hole at the end is ~30 Newtons upwards (3kg).
Have you thought about using these PLA prints to cast into aluminum for a lightweight strong material instead of plastic? I like those motors, do you have the STL files for the motors only? Would love to have a shot at building a few for a RC car.
Great video, I had a good laugh watching this and it's a very interesting design challenge to make a 3D printed quad :)
I just found your channel. Couldn’t subscribe fast enough. I can’t wait to catch up on your previous videos. Cheers!!
Its crazy how far technology has come, having a machine that prints other flying machines.
This is a pretty cool project!
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.
This is so crazy cool! Right up my alley! Subbed!
Will you be sharing your files? / how you winded the motors?
"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!
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.
Brilliant.. Just brilliant !!!
Finally someone did this
Thanks to the TH-cam algorithm for suggesting this channel to me. Great Video C:
incredible video and cool project. thanks
"... layers had shifted so when I insert it it didn't go all the way, so I clearly need to re-print it"
*Dremel, sandpaper and rubber hammer* :
"Let us introduce ourselves"
Lool what a brilliant project :D
I want more! This is so cool
We need to get this guy a Bambu lab printer so he can print faster
I love this guy, he doesn't waste 😘
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
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.
Awesome and impressive !
Interesting project, I look forward to continuing. Very cool frame, could you share the model?
It’s hammer time!!!
What generative design tool did you use for the arms?
Plastic Magnets, copper, shafts, electronics are amazing.
Looking forward to the 3d printed flight controller and ESCs.
Looking forward to the rest of this build... and we dont mind if you just use a dremel - save the reprinting for your final prototype, it surely wont be the only reprint ;)
So even the magnets and bearings and wire are ENTIRELY printed? Amazing.
Man, this is so cool
I'm agreeing on the bed slinger and part weight thing but I believe the motors may have gotten too hot. Luckily, if the board implemented it, you can use the configuration fille to adjust the temps quite easily. It also looks like you could probably mod the original part to get that arm 100% seated without losing much if any integrity.
My heart sank when you said "we're gonna have to reprint this"
This guy makes the best videos
I’ve wanted to use topology optimization for some of my 3D printed parts before as well, but I wasn’t quite sure how to get accurate simulation results that accounts for FDM additive manufacturing of the part. I know that FDM parts are anisotropic, so the orientation of the print, shell width, etc all affect it’s strength. How did you go about it?
Awesome 👏
very cool!!! I would love to try and make something like this!
Great build. This quadcopter is built like an armoured truck.
Is magnetic PLA the best option for the core? Would a metal filled PLA be better? If you can get one that is just filled with iron particles. If not you may have to move away from fully 3D printed motors and instead move onto using metal sheets stacked together like more traditional motors.
Another possibility could be to insert bolts or iron rods into the 3D printed stator, that way the stator is still mainly 3D printed, but may get better performance.
There's two issues there: hysteresis and eddy currents. Iron is actually a poor core material at higher frequencies (which is why modern systems use ferrite almost exclusively, the switching frequencies have outgrown iron).
It'd be interesting to see more testing of the 3d printed motor. Like sending off the core stl to be printed in a ferric metal by a 3rd party just to see how that would impact performance.
6:48 is that an Esp32 on your test rig? I love the things! So useful for everything.
Awesome video and project!
damn this is getting crazy
I wonder if you could create a ferrite core at home. Idk with lost PLA plaster, filling the mold up with powdered ferrite with binder and sintering it?
It would probably do more harm than good. You have to build it up out of thin layers insulated from eachother or eddy currents produce a lot of heat at high speed. Maybe you could print a bunch 0.5-1mm thick layers using the pure iron Filamet, sinter them in a single batch, and then stack them with insulation.
Dude, i'm astonished.
I'm curious to hear more about the specs of the motor w/ your improvements.
"I used generative design"
creates a huge hunk of a non-optimized center section, complains about the amount of filament used.
Hah :D
Are you going to share the files for any parts of this? At least the motor would be awesome!
The shifts are actually the print head contacting the print and the belt skipping. Happens more often at high Z levels. I'd consider adding some Z hop to be extra safe.
Excellent engine refinement, and where can I download the corrected files?
buff quadcopter heck yea
Damn this is very impressive 👍
1:24 Shoulder bolts usually have h6 tolerance which is a bit too lose for bearing's bore, but yes it's a better and cheaper option compared to a regular cylindrical rod or bolt shank.
The arm dsign seems more like topology optimization, not generative design (similar, but not the same). Very cool outcome nonetheless, great project! Loving it.
This is a very interesting topic, can you explain to me the differences between topology optimization and generative design?
@@ramondepaoli1359 In a nutshell: in generative design, you simply set your boundry conditions, loads and goals, and you get the form of the object (different options for different preferences like less weigh, more strength, etc). In topology optimization, you give the program the base form + load conditions and the program subtracts material from the least necessary areas of the object.
Nice work! Would thrust bearings help with the motor
