How Strong are 3D Printed Parts? 1000 Subscriber Special!! 

Algorithm: recommend this channel to people who watch channels like applied science, smarter every day, steve mould, veritasium, that beared bald guy and channels like that. This is great! Bindging.

Lmao the image for plastics. That's too funny

imagine this guy at 1M subscribers lifting a car with just the smallest drone propeller motor he can find can't wait to see that :D

glad to see we are still using American units 3:20

Gets a million subscribers him: infinite torque

very underrated channel even at 3k your channel should be at 10 k by june if you put out more bangers like this. people love watching printer mod videos so that might blow up :) just a thought keep up the good work

Dude -- you are awesome! Keep up the posting!! You are a great speaker, very natural on the camera, witty and you impart so much knowledge in a tightly edited package. But I fear that we may only benefit from your presence on RU-vid for a short time before you are off to bigger and better things. You are clearly very smart and talented.

This is really cool seeing these test and seeing how different material react to this kind of stress

worked in a Strength of Materials lab tensile testing samples all day. I love this video!

So glad I found this channel, you'll do good mate this is high quality content, good luck!

and now, *ITS OVER 9000!*

dude holy cow the amount of time dedicated to measurements for press fitting and gear meshing..... the tolerances you work with. nice job man.

Congrats on the 3000 subs, add one more on that list, hi from Colombia 😁🥳

Yeah it is crazy that you dont have more subs, this is cool

Keep it up and you will have a lot more subs in no time. I can tell you’re an ME. Being an EE myself I was impressed by the gear train design and then chuckled at the 2 arduinos haha. Nothing wrong with that though.

RU-vid finally recommended a great channel 👏👏 I appreciate your content, it's a bit Sciencish

This is so cool Luke! Great video man, definitely subscribing.

Thank you for sharing.

i watch this video 2 weeks after you uploaded it and i see what you have 4k subscribers now, you make a great videos bro. PD: sorry if mi english its bad, im learning because mi native language is the spanish

Pretty cool test

Nice video! I like the idea of a machine with a gear that turns one time every year once you get enough subscribers haha

Well imagine that, this is exactly the question I posed Google. I'm a software engineer by day but I like tinkering with mechanical things and 3D printing is a tech hobbyist dream... I could always use something that, seemingly I should be able to print myself however, I am curious as to its durability because it would have to withstand mountain bike crashes... Or getting thrown into a tree, or RC car crashes or the like :) Long winded reply notwithstanding, I found a gem of a channel and subbed up in the process!

algorithm do your thing you brought me here so bring more people here

This channel is cruelly underrated. Nice video tho

You got my subscription with that plastic joke

I'd argue that picking up a hammer to shape some scrap metal isnt lazy, it's good recycling!

Great video. Would love to see you repeat this with some of the more exotic filaments like Polycarbonate and the Carbon Fiber blends.

What a Underrated Channel...

If you want more infos about the strength of filament, CNC Kitchen is your friend.

super elegant

Totally on par with stuffmadehere and smarter every day! Enjoyable education.

Que CNCKitchen! :) Great channel man!

Next time I come across your channel, you'll have infinite torque!

About the Arduino thing: If the driver you're using is controlled by a simple Step/Direction Interface (which it looks like to me). You could just set up one of the PWM Channels (using analogWrite() with a 50% duty cycle). To my knowledge they run independent of the CPU once set up, so you could still run your load cell code after. Alternatively you could go bare-metal and use one of the ATMega328's Timer Peripherals. Those also run independently of the CPU.

You can run the stepper control in an ISR that triggers on a clock at a set rate and then measure the load cell in the main loop from one Arduino. Could also do the opposite if you want consistently timed measurements.

Thankyou

Now its 34k subscribers)

I like the rough analysis. It appeals to an engineering approach rather than theoretical physics one. Perhaps I'm biased.

Not gonna lie, resin printers are extremely good at getting the most out of plastics when it comes to durability and quality. I finally got myself one, but I bought one of those small cheap Chinese ones, even though it cant print out anything too big I'm quite happy with it. Also for someone lacking in space the fact that all my "filament" is a liquid resin means it take less space to store all the types of resin I have.

Plastics example killed me😂

1. use threads instead of this high torqued paracord roll 2. use 1 Arduino and take Measurements using Timer Interrupts 3. If using rolls for converting rotation into linear motion, reduce the diameter to a minimum and by that reduce the momentum on the shaft. Use the exact shaft diameter or increase the shaft diameter to be exacly the roll diameter or even bigger.

This was brutal to watch.

you should just be able to call the read commands for the load cell and write commands to the motor in the same loop, id have to look more into the arduino documentation to see if you could do this asynchronously but even as a synchronous action it likely would effect much because it would be synchronous to the clock which is that 16k crystal i think... goes fast

You can task switch with an arduino to do two real time operations (like stepping a motor and reading a sensor), but you have to be pretty tight with your memory.

to graph with an arduino while stepping a motor can be accomplished with program "scheduler" now technically you can make it way simpler but its the same idea basically you always have the arduino doing something i like to program my projects based on cycles so as an example lets say you have your stepper program you have that run write down how many cycles it can do per second or have the arduino tell you through the serial port and do that for each major function you have so measureing, and stepping the motor in this case then you make a variable i usually have a basic function that takes a the previous cycle number and the maximum cycle period and if the number is greater or equal to the max it resets the variable to zero otherwise it adds one to the variable and returns the value then i have an if statement which checks if the variable that i wrote to earlier is greater then or equal to the cycle im looking for i find this method useful for tuning multiple functions ones that need to run more often and those that usually dont need that long you can combine this so that you have a function which steps the motor and a function that takes a measurement and prints it to serial and if the serial output is too slow you can increase how many cycles it takes to execute that code or if the motor takes too long to move lower the amount of cycles used.

I think MegunoLink could be used for controlling the motor and logging the stress data. With it, you can make control interfaces for your pc via serial with graphs and other menus

You could take a lot of bending load out just by lowering the test piece so it's tangential to the pulley

Hi, im really intersted to know is a gear could be made to withstand the use in side a aprilia rs123. the water pump and balencing sharft but not the gearbox its self. AP023443 plastic gear

What tolerances do you use for you press fit 3D printed parts?

what the fitting distance between parts you print at? .2mm?

Congrats on 3K subs… Uh, start printing a new gear😄

The main problem I see with this is you haven't accounted for scale. Things need to support their own mass in addition to any load, which is why, for example, ceramic is often used for military-grade armour rather than metal. At the scales you're looking at, you also need to start looking at internal stresses; a Rupert's drop is a good example of how internal stress can _greatly_ affect an object's strength under load or impact.

Ah, you new age engineers. Need more processing power than all of NASA had available for the moon landings for this simple task that could be performed using basic hardware store components, without involving any electricity at all.

Bro that ain’t unusual that the crap I would do

You should put a note in your description that this are affiliate links

Now you need 17900 get that (this is a joke)

Are you an engineering student by any chance?

You Need bearings

I can never find just something that test strength between 3d printed parts and molded plastic! If 3d printed is weaker, then what even is the point, apart from it being easier and less costly? It's just about filament vs filament! Who cares!?

3d print a fgc-9 lol

Okay, but CNC Kitchen?

Arduinos are really bad at doing more than one thing at a time. You need rtos or an esp32 or something

Plastic example. 🤣
