MAKING A GIANT 3D PRINTED EXCAVATOR PT.1

Check out PCBWay at: www.pcbway.com/?from=Ivan for 3D Printing, Sheet metal fabrication, Injection moulding, CNC services and more!
I'm building a giant excavator using the 3D printed Miranda Blocks that I designed to build the Go Kart to race Matt Denton and his lego inspired Go Kart. When I started building the Go Kart I realised that there were a lot of improvements that could be done to the blocks but Iterating the design on that monstrous scale was going to take a lot of time and be quite wasteful so I created this scaled down version of the blocks which took a loooot of filament so go and send some love to PolyMaker for letting me go wild with their filament! (aff link): bit.ly/3i4PEkd
As the goal of the blocks is to be able to use and reuse them to prototype different projects I needed a project with a little bit more punch than a car so I decided to try and build an excavator.
This excavator design is already too big for these blocks but that's intentional as I want to test the limits of the design so I can be sure that I thought of every detail before starting to print these at full scale.

I really like the idea of these blocks. I can only imagine how much print time is saved with every one of these blocks you can re-use in another project. :)

[@StevenIngram]

It also dawned on me, if you had one of those conveyor belt 3D printers, you could make arbitrarily long beams that are compatible with Miranda blocks. :)

[@ivanmirandawastaken]

I've been thinking about getting one just for that

[@webrosc]

@@ivanmirandawastaken you'll buy one and not make one??

[@brandonmack111]

@@ivanmirandawastaken or building a giant one? 😜

[@StevenIngram]

@@ivanmirandawastaken cool, and if you make your own, you could build the conveyor from Miranda blocks. hehehe :)

[@patrickellis3205]

Ivan Miranda, the only man in the world to successfully dial in a 3D printer 😬

[@realVertiqo]

The Miranda Blocks became very sophisticated, im impressed!

[@malloot9224]

Normal 3d print channels: look at the huge prints!! They are massive Ivan: this is the scaled down version I'm sorry Much love, awesome project as always

[@el_es]

9:56 flashback from 'Why Mechanics Hate Engineers' ;)

[@ivanmirandawastaken]

Yep, that was totally missed in cad

[@TheGreatSteve]

I like the screwdriver. I think Meccano would be a better product if you could attach the fasteners more quickly.

[@boonjabby]

I am envious of the amount of filament you use. I virtually create my versions and sit on them for some time before printing before getting the courage to make the 'final version'. All this to save filament haha

[@samuelgonzalez7783]

The 3d printed screwdriver had me laughing a bit there. Great build

[@inventiveowl395]

Will definitely get used as a hammer at some point..

[@wernerhiemer406]

@@inventiveowl395 Or as a chisel, just in case the refrigator gets too cold.

[@Engineezy]

Flip the nuts for bearing mount- genius 🤯

[@Rob_65]

Each time I see you use these blocks I am amazed by all different uses. You make if look so simple but as an engineer I recognize the amount of work that has been put into the design of this system.

[@inventiveowl395]

8:12 - I'd just like to point out that the bearings you used seem to be purely radial. The base rotation creates axial and radial force, but the axial part is much more significant. Those bearings might break.

[@G_REX_3.14]

True ! A couple of bearings beetween the horizontal parts would make it stiffer and more durable👍

[@davidedwards9157]

He might be happier adding a thrust bearing or just using a 'lazy susan' bearing. (I mean, there are bearings specifically for this, but they're specialized enough to be expensive...)

[@oddzc]

Im pretty sure the bearings despite not being designed for that use case are not the weak links in the chain here.

[@08Jacky15]

Glad I'm not the only one who thought this.

[@Thierry080]

Radial bearings have more than enough load bearing capacity in axial direction than is needed here. This won't break anytime soon.

[@b3nny90]

Now I've got another project to add to my list. This will be good fun

[@guillaumepicard8666]

Ivan I wish you could post the amount test and failed prints !

[@edumaker-alexgibson]

Love the 3D printed screwdriver. Very RepRap spirit :)

[@nonfam4594]

You, your projects and Polymaker are awesome!! 😀

[@XTJ7]

So we can eventually get steel miranda blocks as well. That is an interesting prospect.

[@malloot9224]

That would cost an arm and a leg but worth it

[@davids8493]

I am always impressed! 👍👍👏👏

[@hughessay1372]

Your projects never cease to amaze me. Thanks for sharing!

[@jana171]

This is GREAT... Loved this, and my mind start to spin with all the possible projects that could be done this way in larger scale, simplifying real world prototype builds using standardized modules.. you are taking everything to another level Ivan, and I LOVE it !

[@Vernon1xx]

Unbelievable!!!

[@MGC819]

you should start a product Line with these blocks

[@Liberty_Prime199]

this is cool af

[@robrs210]

Another big block builder 👍 nice one Ivan. I got started on the big block but Matt also. I have the large bulldozer Matt did and im working on the technic go kart kit 42048 and the race truck, both five times Lego scale to match the bulldozer 😁

[@crazybeaver5789]

Love It

[@DogmaFaucet]

A set of these in CF Nylon would be a super useful jig system for so many projects. Kinda pricey to pint in the large sizes. I need to get at it and make some gridfinity too.

[@markkalsbeek5883]

If you need something that strong, why not use alu extrusions? They're like Legos for engineers!

[@Creative_Electronics]

Awesome video as always Ivan :) I'm looking forward to see the next video :)

[@mururoa7024]

Dang impressive as always. 👍

[@frdesign3034]

AMAZING REALLY CRAZY JOB. I ALSO TRIED PRINTING BLOCKS LIKE LEGO, BUT THESE ARE REALLY HUGE BRAVO!

[@Zachary3DPrints]

OH wow, Ivan, you rock with these amazing designed blocks! @polymaker3d Thank you for helping to sponsor this channel!

[@Emulation_Inflation]

Nice!

[@austinsmith1843]

I love you vids so amazingl

[@janvejtasa]

Having a 3D printer in order to be able to print custom parts. Ivan: I printed a universal system to build things from. :D . Awesome video man! Love what you do with technology.

[@brandonmack111]

"I was working on this big project, so in order to make sure it would work, I decided to start another big project" ~Ivan, basically. Not that I'm complaining, this is awesome, and these blocks are amazing. I kinda want to print out some even smaller ones for my kids and me to play with..

[@3DMusketeers]

Amazing Ivan! Love how you made it fully parametric with values! I need to do that more often in my designs!

[@Psychlist1972]

Polymaker was probably like "We should just agree to provide all the filament he needs. I mean, how much could one person possibly use?" They probably had to open another factory just for you :P

[@ivanmirandawastaken]

😅

[@Fritzpuddel]

This reminds me of the old Lego Duplo Toolo series .. Such a cool idea!

[@Todestelzer]

You know your stuff. 👍

[@doof3d116]

Thank you for always reminding me that 3d printing has limitless possibilities!

[@ivanmirandawastaken]

Yes!!!

[@1337Elisha]

what profound ignorance

[@jstagzsr]

you live as close to my dream life as humanly possible.. ever since i was a kid i was taking apart all my toys and rebuilding other things out of them. anything with a motor was ripped apart and cars and very simple robots were built. now as an adult i work maintinenece in a machine shop where i get to play with fun stuff all day and be paid for it but my dream is to rent a warehouse and basically do exactly what you do.. Play all day with awesome stuff i built. and since 3d printing becoming a thing and cnc mills/routers became desktop sized and able to be bought for only a few hundred bucks, it opened up the possibilities from parts i melted together with a lighter to make stuff kinda work to making exactly the parts i need, when i need them, and making all the ideas in my brain a physical tangible reality. we live in an awesome time. Keep doing exactly what youre doing and ill continue subbing and living vicariously through your videos!!! haha

[@joelguay4452]

Something "Simple" XD. Ivan is the GOAT :D

[@coaltowking]

This is awesome. One note. The arm on an excavator isn't offset; the cab is.

[@cosmo9882]

Cool

[@thedream7504]

You are great !

[@SeanHodgins]

I'm pretty sure you have a secret room full of giant 3D printers running 24/7.

[@hambaallah1948]

Red filament gonna stonk when ivan start print

[@grahammcnally4799]

Beautiful work as always. How hard would it be to use stepper motors in your linear actuators? I think that might solve the speed problem. Keep up the good work love your stuff.

[@togden88]

Hey Ivan, love the looks of this! One note that might be helpful-- typically in these sorts of rotating turntable arrangements, the small gear (attached to the servo) is stationary, while the big gear moves. Based on 11:52 it seems you currently have it set up in the opposite way. If you run into issues with the servo, consider switching it around! :)

[@markkalsbeek5883]

What's nice about doing it this way is that all the wires and the controller/battery/radio get to live on the platform, without the need for slip rings or anything.

[@villageblunder4787]

FWIW - Excavator booms are pretty much on the centre line.

[@Scott_A]

Awesome project, you should try to get threaded rod with a 2 or 3 start thread, then the movement would be much faster. They use this on certain valves that need to be opened or closed rapidly

[@dustinkervodka]

Great work Ivan As always Though excavators don’t have the arm on the side when in bigger sizes .

[@ianmcnab9534]

Nor on the smaller ones either. It just appears that way.

[@LR-qi9rj]

btw id reccomend checking out brass bushings for joints. For anything that doesn't require fast movement for more than 360 degrees, bushings will be stronger and cheaper. Bushings for low speed and high torque, bearings for high speed and low torque.

[@obfred]

No "SPACERS"???

[@greenevegiebeast]

Super size techno

[@nou5440]

wonder how well plywood would work for those flat beams

[@ivanmirandawastaken]

I guess it would do well, It is just a matter of getting the same dimensions and features on the plywood

[@MAYERMAKES]

interesting DIY hammer to put together the pieces.

[@baschz]

The video just started but I am already sure I will like your screwdriver tool most! :D

[@baschz]

Ok, your smile when it started turning just beat it :D

[@ForNess]

Amazing project! Just by curiosity, what is the cost of the aluminium 3D printed part? :) Thank you and keep going! :D

[@James-sg]

Doesn't that particular servo model come in a 360 degree variant though? At least that's what I see on aliexpress

[@ivanmirandawastaken]

Maybe, but not the ones I had.

[@NathanaelNewton]

Wow this is genius, it's like a giant erector set with home printed pieces, the possibilities are endless!!

[@dtec30]

must have a hec of a print farm ivan

[@Roobotics]

For the pegs I'll bet you could embed a steel shaft/threaded rod(s) into it for pieces that need extra rigidity, nuts at the ends to hold it all in compression.

[@MechaNexus]

soon we'll see a video of Ivan building a 3D printer made up of Miranda blocks to print bigger/longer Miranda blocks

[@PaweWWnukuLaboratory]

Great! Try to use a tube with thread at and, it looks like a hydraulic cylinder and the threaded rod is shorter 😁👌

[@petergamache5368]

Those poor little servos! It might be good to put an ammeter on the power supply to show how hard they are working.

[@ivanmirandawastaken]

Very! At least the one at the bottom of the arm. Everything in this project should be 50% smaller

[@danielalonso7027]

Fantástico

[@markkalsbeek5883]

I think it's be so cool if you started using hydraulics in some of these. Small diameter hard pipe is pretty easy to work with and conceptually it's all pretty simple too. I think the hardest thing might actually be to find a hydraulic pump that is small and quiet enough for indoor use haha.

[@natecus4926]

Are the stls for these blocks available anywhere? I’d love to print some out!

[@bamsebrumbamsebrumen5403]

So when will you go water-hydraulic?😁

[@duzer3000]

Вот это размер ) круто!

[@astrydlilium7501]

Suggestion: Change the last part with a lamp and add a remote control maybe with some Alexa routine.

[@woodwaker1]

Reminds me of the Erector sets from the 1950's when I was a kid.

[@DumahBrazorf]

Do you print the screws in vertical? Aren't they weak?

[@TheInsaneupsdriver]

got a challenge for ya, multi material large format belt 3D printer... with that you could make almost anything in one print.

[@brianjones3644]

Bucketchains : I wonder variants what you can do & what durability tweaks can be introduced =)

[@Nathan69]

Where do you get so much filament

[@jacquesb5248]

wonderful design! you sell that as a kit!

[@wanglydiaplt]

Tracks to make it mobile next? Then a dump truck to fill with it? 🙂

[@taleg1]

¨You just reinvented the old wodden meccano or what it name was, that I remember from my childhood, more than 30 years ago.. :D

[@Schnabulation]

Any reason why the modified servo and not a stepper?

[@MCsCreations]

Wait a second, Ivan... You don't use 3d printed boxes? 😯 Unsubscribed!!! No, seriously... Fantastic work as usual! 😃 Stay safe there with your family! 🖖😊

[@HermanKruisman]

You can just pull the pin out of the end gear :)

[@poupou_3]

Super projet, mais pourrait-on mettre dès servomoteur plus puissant ?!

[@BLBlackDragon]

Didn't go with some small RC drive motors? Hacked servos, instead? Interesting. However, can't argue with the results. This is very impressive.

[@websitesthatneedanem]

👍👍👍👍

[@ivangamer8022]

awesome job my friend

[@ianmcnab9534]

I'd just like to point out that no the boom on the excavator isn't offset from the line of rotation.

[@DonsArtnGames]

12:10 O_____O That is a LOT of filament... Mind sending some my way please?

[@makewithmegma]

🔥💕👍

[@isakbiker]

Is it possible for you to upload the fussion 360 or stl files so all of us can dowload it, i did not find it on your website so them are maybe for private use.

[@predator-wx8qt]

ivan if you remember the big 3d printer you made it could you give me a link to thys hiudge bed heater 500x500?

[@onerian8178]

will the files for the blocks be released in the future? maybe for sale or something?

[@5FSF]

What is the little thing you're plugging the motors into to test them?

[@thinkdunson]

continuous rotation servos are just as easy to buy as regular servos. also, i think that M logo on the bucket teeth may be copyrighted by BMW.

[@theninjascientist689]

oh to live in a world where companies can't sue you over a singular letter

[@wanglydiaplt]

Hey Ivan have you tried using the trick of saturating parts with crazy glue to increase their strength??

[@Accessgp]

Hi Ivan, you are simply a genius at the work you do. I think renaming your channel to "incredible Scientist" would be more appropriate 😁

[@mrkthmn]

Hurry and buy from whatever you’re gonna want from Polymaker before this man puts them into bankruptcy! 😆
