probably a lot more than you would expect, I have a 5:1 planetary gear set printed in ABS I have been operation for over 600 hours of continuous usage. if the part is desinged reasonably well and not abused 3d printed parts can operate nominaly for extended periods of time.

I guess and I repeat I GUESS, maybe are the certification? The 3d prints that they made are some standard industry level certificated print? Because if not, I suggest to buy a 3d printer for the same price and do it yourself but abs may be tricky to print (and dangerous) under some point of view...

3d printers have opened up a whole wave of creativity and Im here for it. Interested to see what else you create Michael!

3d printers made me realize how uncreative I am. I always referred to myself as a "genius" with all these ideas but too lazy or lacking the resources to make them. Now I have 2 p1s printers and can make anything and it's like my mind is just constantly blank lol. I'm glad there's people like this guy sharing their creative designs though :)

Been a fan for a while! Love the way your channel blends informative stuff with fun projects, and it’s all just shot so well and the video and audio quality are great!! Keep up the great work 🫡

Curious how these compare in size to power and weight to power vs the store bought one. Pretty cool! I’ve been making a lot of things that I could buy cheaper if I accounted for my time but knowing the ins and outs of a thing is satisfying and when something breaks then I’m not afraid to dig in and get it going again.

great project! 👏😎

Honestly, incredible video man. Love the growth on your channel.

Awesome, this would likely work well for a standing desk build. thank you for sharing it!

Perfectttt video.. was looking for a 3d printed actuator for a coffee press I’m working on. Thank you sir!!

Great! I actually need a linear actuator for a current project of mine - Thanks !

Cool demo! I love this stuff. Interesting to see how these could be used in the real world on robots or gadgets since you went to the trouble of building it.

Nice experiment & great results. Something to keep in mind for my future projects.

Just found this channel, 100% you will be very successful if you keep doing what you're doing, love your content

unreal vid man, i know im gunna be watching a video one day of you with 500 000+subs! cant wait to be part of it

Nice build. I use a lot of electric actuators. You will find this type of design is much stronger in compression than tension. A lot of the actuators use a nylon nut and are surprisingly powerful. I like the fact you used a square section as a keyway

Awesome! Adding to my to-make list

Hi, your video just popped up on my main page. Very cool. Someone might already have mentioned it, but the gasket is probably there to keep the water out, not the grease in. These type of actuators are often used to open/close roof windows where they might get wet and need weather sealing. Also you could make it stronger by using more gears since I am guessing you're maxing out the motor when crashing the soda can. Awesome work. Subbed.

This is awesome! I’m interested in seeing a tiny diy linear actuator like with a 1cm^2 footprint

Well done The wiring diagram is surprisingly simple, let me explain how it works Check at 4:35 Until actuated, each switch let the current flows in both directions from one end of the circuit to the other When either switch is actuated, the current stops flowing through it, and the diode that bypass it allows the current to flow in only one direction instead, the direction that moves the actuator away from the stopper I did not know that wiring limits switch would be that simple, thanks you for showing us this

Yeeeessss THANK YOU!!! I've been wanting to build some of these for a project for a WHILE!!! thank you for saving me HOURS of trying to figure out how to do the cad to make these! Sure its only 35 bucks for one....but i need more like 30, and a few different sizes lol. now that ive got the cad for this i should be able to make the adjustments i need for the project from there. :).

What kind of project are you working on?

I'd love to see a video on the gears printed with the 3:1 fast:tenacious mix - maybe a redo of your tough pla vs. resin gearbox testing. There are loads of FDM PLA gear testing videos out and each one says "it'd be interesting to try this with a different material like ABS or nylon, or resin combinations." but never any follow up videos. There are 1 or 2 videos of ABS/nylon FDM gears but your other resin gear video is the first I've seen testing resin gears legitimately (and I think that was just cheap abs-like clear resin)? The combo of tenacious (for some toughness) and fast (for wear resistance) seems like it has a lot of potential!

I would love to see a fast and precise version of this linear actuator

Curious to see if this would work with a tpu extrudsion/nut. ie a flexible linear actuator that can bend whilst moving back and forth. would be useful for artifical muscle setups/soft robotics

"wheres the fun in that ,lets reinvent the wheel" earned my subscription .

wao. really nicely done .... thanks for this ...

This is amazing. The project use is endless. One is for a car spoiler wing.

Finally, something usefully can be printed.

Did you ever read the 'Guerilla guide to CNC and resin casting'? Also, have you thought about building parallel robots with the linear actuator? Eg Stewart platforms or delta bots.

love your stuff man!

Cool channel and great work! Subscribed!

cool stuff! the grub scrub hole on a motor shaft gear seems to be a weak spot for the gearing; could be worth it to design a gear-matching "plug" that you could lightly glue in, after tightening the screw (so that it doesn't turn - better yet, make it a square hole, so it can't)

Man. I love this.

Well done mate!

Just what I was looking for. Interesting. I'd like to do some calculations on this and make one myself. Cheers.

great work, please do more stuff like this :)

Fantastic work, dude! Nicely done! 😃 I just subscribed... Keep the videos coming! Stay safe there with your family! 🖖😊

What are the weight-differences between the metallic bought actuator and the plastic homemade one? If the plastic is lighter and cheaper, it might be a big advantage for both places where price or weight is important such as DIY robotic-arms

I like your think once, print thrice method. I am a keen user of that method too!

Awesome Video. Do you know what reduction the gears provide in the casing? I'm looking at trying to change this print up to fit a nema sized stepper but need about as much torque and force that your actuator in this video were capable of but I just don't know if I'll find a stepper in my budget. Cheers

This was awesome. Funny thing, though, is that it made me think of a video that I watched a little while ago. It was a video of a guy who makes 'googol' gear set ups. I'm wondering how attaching a linear actuator would work to drive one from the low end, and how fast it could get the high end to spin. I'd also love to see how one could balance that out as useable torque. LOL! I love it when a video can get me thinking of another one... especially when they seem to tie in so well. Cheers!

clean design

Great job... of course we want bigger, faster, more power :D

Very interesting thanks for sharing

Вполне не плохо получилось! Симпатичное изделие своими руками на 3д принтере.

Very cool. Trying to figure out a way of using motors or actuators where I can have a 10kw gas generator I have inside generator housing for parents house slide out of the building via actuator or motor system. The generator would sit on a solid floor piece and pushing button would push floor and generator outside of the shed or retrieve it. They are getting older and have hard time moving generator. We are trying not to have generator operating inside shed which is up against house for fire concerns prefer it be outside when running not in contact with the house. I could put insulated exhaust in shed and add large air intake, but we do not want fire risk to house when generator running. What can you think of for proper actuator or motor and pulley/gear system

DC motor torque is proportional to current. you should leave the DC supply at the maximum voltage you want to apply but then use the current limit setting to control current up to the maximum current rating of the motor to get a true measure of thrust vs current. Remember its current that primarily limits the motors output at slow speeds. Interesting project. thanks.

Very nice!

What's the best way to increase speed without losing torque? Would a faster motor do this since the gearing is going to be the same?

Well done!

looks great. how much do you think one cost you to build?

That's really cool. I was going to build one similar to that, just my 3D printer isn't liking me. So i moved on to my next project and could use a little advice. I'm basically trying to build a wench. It doesn't have to be same to support much weight, just a Go Pro on approximately 100 meters of twine. I was thinking of using an Esp8266 our Esp-32 to control it and display the distance. Got any advise? Any help is appreciated.

The seal isn't to keep the grease in, it's to keep dust out. Grease plus dust means a thick nasty gunk.

I like torque more than a speed nice video man that thing is really cool 👍

How strong is the actuator under tension forces? how much force can it pull?

would be awesome to see some gear comparison tests, most channels that did them just print them and they go "see, they spin!" but never check out the wear under load and the maximum rating, just no load movement.

Lead screw is self locking, which means the load will not move the piston when powered-off. A metric screw does not have this characteristic. I understand it's meant to be a cheap build, but the end result is not 1:1 to the commercial unit you're comparing. Otherwise, it's a nice build and I learned some tricks for 3d print design. Keep it up! :)

Very nice idea. However the linked motors are not available anymore and I could not find any with the same dimensions :-(.

We are in desperate need of a quality outdoor (not water proof but resistant aka roof of outside front door) PTZ open source IP camera hardware! And I think your our man!

Did you put thrust bearing end of lead screw? I made some years ago linear actuator where i used thrust bearing and gear motor was directly behind screw, bearing take all pressure load from lead screw.

So, you made a linear actuator with some 3d printed parts, a few screws, and a linear actuator... I wonder how well it would work 3d printing the main screw instead of buying it. Also, pulling force should be lower here due to layer separation. Edit: ...thinking about it more though, using screws and other stuff rather than printing most of the parts is a great idea, since those are otherwise the failure points, and they're really cheap. So, I might work on a more general version that's pulling or pushing, and supports different screws/motors.

This is a game changer. We have to find a way to integrate blockchain technology to it and Bob's your uncle!

You need a back emf diode across the motor , and the correct way for the connections

Next: Switch to a proper square thread screw and see how much force it puts out.

Can you print some herringbone gears? Awesome project!

Two things: How many cycles can it sustain at a high force level. I wonder about the strength of the printed gears mostly. It would be an interesting project to create a servo using an RC PWM interface. I think you could use a variable inductor to measure the position. Another method would be to just count the rotations of the lead screw,

Well done, and great video too! How much effort is it to extend the travel of the actuator? Perhaps you can use this project to make an open source motorised standing desk

Thanks! Should be pretty easy to make the travel as long as needed.

Great Video and Great Work ;-)

Can you make it faster and stronger by improving the dc motor to a brushless and the gear reduction? That would make a cool proj for a high performance linear actuator

Precision is also paramount in actuators !

I like this one

Would be cool if you built a hight adjustable desk with this!

Add a rotary encoder to get positional feedback!

Cool video. One question though - what's the secret behind Multi-Level Linear Actuators? Once the attached screw fully extends, does it switch to (literally) another gear - or are the different sections leveraged so that all 3 sections are expanding at the same time?

You might be really interested in watching videos on how the james webb telescope linear actuators work. They have a low and high precision mode, using just one motor. They are very clever.

Might be good to know.. of cause, if i need one, it don´t really matter, but some day i might need a hundred of those, and then it might make a diffrance. Or if a specially dimension is needed, that is also possible

Project idea - Use Linear actuators to control a set of Top-Down, Bottom-Up (TDBU) Shades with the ability to roll in metal shades during storms. Typically, TDBU shades are cloth pleated that compress down into a box of the Bottom and a Box on the Top and the boxes are press fit into the Window sides. Want to look out without someone seeing your messed up room, just lower the Top-down box. Want a cool circulating breeze, then Pull up the bottom box and also pull down on the Top box (and open the windows of course) One issue is that typically light can get in around the sides of the shades so it would be nice to put the bars inside side tracks to keep the light out and to keep the bars from Racking. Having a secondary metal roller shade (either Top-down or Bottom-Up) that would protect the room from storm damage (or from Zombies) would also be a cool add on. Just a thought.

@markkalsbeek5883

I think a linear actuator is maybe not the best fit for that, since it's slow and high force. The forces there are small and the displacements are large. Just winding the line around a pulley/drum using a stepper would probably do fine.

Did you have to make the log brown?

Whats the significance of the diodes solderded the limit switches?

O yeah totally crazy.

4:37 the secret is that electronics run on magic smoke, and if you break it and let the smoke out it won't work anymore.

maybe you could also try making one of those high speed linear actuators??

FYI - the threads for a fastener (bolts/screws) will not work long term as a replacement for a power thread (lead screws)

Model aircraft retracts are really expensive. This video is great for me to scale down to make some servoless retract actuators for large models.....a model of 30Kg....so not super large but definitely a big boy's toy.

Not sure where are you located, the design is really robust, but also would design a model that hides the wire and the switch to give it a little more potential for use in outdoors. Nice video btw 😁

What can I do to increase travel speed I only have to move a short distance.

Nice, how much would you say it cost you in off the shelf parts?

You just made my hobby robotics cheaper and a lot more satisfying. Subscribed!

What sizes for the bearings any bom list :)

Now imagine if you printed it in CF-PEKK, that's self lubricating and re-inforced. You'd have a linear actualtor that could be operated in environments that nothing else could work in. You could have the thing work inside of a highly corrosive environment without excessive wear due to the environment.

project idea: 3d printed toy excavator... could use the linear actuators to rotate the crane, and articulate the digging arm, and bucket... =D

Why is Boston Dynamic's Atlas so expensive? Can you break down the cost part by part and also show some pointers on how those costs can be lowered in future.

That is how the elevator is moved on a airliner!

that's cool 🙂

If I wanted to build one one of these but needed it to go really fast, but not nearly as strong as this, around 20kg, would I just need a lower gear ratio and a higher thread pitch?

Yeah, either of those. You'd want to do some math to make sure there's enough motor torque after the gear reduction to push 200N (including an efficiency factor), but either of those could be adjusted to change the speed/torque of the motor. Depending on how much faster you want it to move you may need to change the motor to one with higher power, though.

I wonder how many times it can lift a certain weight up till it breaks

Make an Orange juicer it sounds possible after making this linear actuator 😃
