I love how the prusa factory looks like we imagines factories as kids: Way over engineered and ridiculously cool
Because they were part of us kids which imagined them like that.
this is indeed over engineered. You do not need optical sensors and 1000 moving parts. You can just use a weight to count those nuts and bolts...
@@Matthew_RemoveafterwashingTell that to the guy who gets 9 bolts in his 10-pack. I've been that guy and I definitely wasn't thinking "at least they didn't over-engineer their production line".
@@ChillyJack so, the weight was not sensitive enough, it's really that simple 🤷
They should have set the weight limit a bit higher, so that the screw count would've fluctuated between 10 and 11 instead of 9 and 10.@ChillyJack
As an automation engineer I can promise you that this is the coolest factory ever. Selling automation to companies is like pulling teeth for some reason. The only folks truly embracing it are the big ones, and it’s truly paying off. The more automated the factory and the more autonomy the humans have, the better employee retention is, and the better the machines run since the employees have real experience with those machines and they stick around since they often feel more fulfillment in their jobs.
"Selling automation to companies is like pulling teeth for some reason" because then there would be one less ambiguous thing used to micromanage humans replaced with something measurable and accountable making automation an existential threat to the c-suite.
There's also an up front cost, and especially when a company is public, they care often more about short term budget balancing over saving money and growing talent over the long term
I felt alot of fulfilment at my position in my company as a machine operator, until they added more automation to the department and reduced the team from four men to two. As the newest person there I was moved to another department solely based on seniority. This all being despite me being the fastest learning operator on the new machines, and having more overall competency that the two above me in seniority.
So there's a practical example of why some companies shouldn't be adding automation, they now have made two separate departments less efficient, and have taken away confidence and fulfillment from employees.
This has effected my views on the company seriously enough that I'm considering cutting short my employment in favor of other opportunities, and the worker in my place only grows more frustrated at a work environment he's not suited to and will likely leave sooner as a result.
Totally hit the nail on the head there. It's still feeling valued for making sure that the product goes out correct
I like the confidence in their product that they use the parts it makes as part of their production process.
I'd have more confidence in this sorter if the logos were printed correctly.
@@blindside_o0 For machines they make to use in their own factory they're probably more concerned about the function than the look of the machines.
However, it does look odd on this video that the logos aren't correct - how does that happen? Getting the logos right shouldn't be much of a challenge.
@@blindside_o0 The logos look smashed, not recently printed, probably moving the machine around
@@blindside_o0 about halfway through, when the camera pans past the intake buckets, you can see the 3D printed labels on them and they look perfect. Like fofopads said, they are probably smashed from moving the parts around. That honestly gives me more confidence in the strength of the prints because it looks like they took a beating and are still working perfectly lol.
They use plastic parts in applications suitable for plastic parts, what is so good about that? You could easily reprint it all with an Ender 3 and it would work just as well.
They didn’t build it too fast, they built it with growth in mind…
That's not what he said. He said the machine does its job too fast (a good problem). Because of this, they only run it every so often to replenish stock as needed so they don't end up flooding shelves with unnecessary amounts of stock.
@@EyebrowsMahoneylook again. It has different hoppers and buckets. They can expand it to count nuts, or wrenches, or different length screws, or accommodate projected demand. avocadoarms358 was correct.
@@EyebrowsMahoney and that means that if there were more demand it could just run more often to keep up with demand.
Thats what they meant by growth, they have plenty of headroom
@@EyebrowsMahoneyNo, it’s not a problem in any sense.
@DreadedEgg in logistics, overstock is a problem. If you have tons of product, where are you gonna put it? Is that not a problem? The additional costs to warehouse and store it are most definitely a problem. It's a good problem that their machine can outrun production because it allows for growth. But unnessecary excess is generally a net loss in production because it drives up overhead without increase in revenue. In fact, it costs money to run the machine. How is that not a problem?
Prusa's factory looks like the factories I make in Satisfactory

"this machine is way too fast for what it does" lol. This was basically the way we bagged potato chips except it ran at 90 bags per minute.
Hahaha, yeah I worked on a line for bags of shredded cheese. The chokepoint was always making the cardboard boxes fast enough to put the bags in them and feed it through the taping/labeling machine, (which itself became another common chokepoint because it broke down all the time.)
The automated spinning hopper thing that sorted bulk shredded cheese into 5 lbs bags was somehow the most reliable part of the whole operation. I mean we were probably doing closer to 30 bags per minute, but only four bags went in a box and I'm pretty sure they weighed a little more than your potato chip bags.
Link to STL?
I think it might take a while to make 😂
😂😂
🤣
Probably dont want to share that for free buddy
@@D3nn1sit’s a joke….
I like the way this works - the mechanics are pretty basic and optimistically engineered, but weighing each batch to verify count and recycling incorrect batches makes for an accurate and verifiable overall process.
I was going to say the same thing. Weighing the screws would be far faster and far more accurate than using optical sensors to figure out the number of screws dropped.
Weighing is common
"I need these screws sorted" Me "Is there a time limit on when it gets done? Eh HEY TIMMY LOAD UP THE 20 PRINTERS"
The packinging machien by itself is nothing new.
The real deal is that 3d printing gives everyone a massiv possiblity in relativ cheap automatisation.
The biggest accomplishment of all would’ve been correct spelling and grammar in your comment
They also need engineers to design and make a functional and reliable system. This might cost less in parts but it will cost Prusa more in engineering time than just buying a machine would have.
Counting and packaging parts is a very common task. They likely could have bought the parts prepackaged in their desired quantities.
@conorstewart2214I think you're misunderstanding how capitalism works.
The company that packages the bolts is making a profit by packaging the bolts for you. If you're doing _enough_ bolt kits, packaging them in-house with automated tech is always going to be cheaper, because you're not paying for the owner of the packaging company's cabin, boat, etc. if you're only doing 50 kits a year, then yeah, outstanding is the better deal. If you're doing thousands - bringing it in house improved both cost and control of the product.
Seen similar stuff in candy companies where they drop sweets into a dozen trays and then drop the trays that add up to the right amount into a bag. Screw counters with knock sensors are also no new technology. Nonetheless, this is a very nice implementation of this type of tech.
Need a How It's Made style video on just the complete picture
I wish I could get sent down a fun rotating slide into a catch tray :(
Prediction: Musk will acquire Prusa and Boston Dynamics, then merge it with StarLink, and name the newly formed conglomerate "SkyNet." Their first celebrity spokesman?
Arnold Schwarzenegger.
Prusa is what Satisfactory looks in RL
Prusa needs to sell some of these to IKEA.
Why?
I don't know why so many people think this is something new or innovative. These type of machines have been around for a long time and part counting machines are extremely common in manufacturing, everything from food to screws.
Awesome! For this i LOVE 3d printing!
Haribo has those machines in professional.
I actually operated them a somewhere around the turn of the century.
So now I gotta master my Creality Ender 3 Pro weaknesses and produce results like this when I tackle them with my creativity.
Wow that matchine is super cool, but does it count correctly?
They probably have an additional scale that weighs the finished bags for QC or just do QC by hand…
1 screw is fairly large part of the overall weight so dunno why it wouldn't count right.
seems quite complicated compared to a mostly mechanical solution, but i guess this is more reusable for different small parts.
you could just have the screw providers machine do the same thing at the factory as well, but maybe you need bags with 8 and some bags with 12 and some with 16. i wonder if it can mix different parts into same bag.
@@lasskinn474they do have to have bags with different quantities for different products. I do know that the bags that come with the printers and the multi-material unit are fantasticly organized.
As long as the scales have enough accuracy
Lego uses basically the same method of putting things on a scale. That’s why you usually have extra parts that are really small- they have the system error on the side of caution and try be a little more than what is expected if it’s super close
pack-man lol
Why the optical sensor if the screws get weighed and the scale decides if there is the right number of screws in the bucket or not?
I worked at an HP factory. this is generally accurate to what the line looked like, just with much less 3d printed parts.
It's so slow compared to the machines I work with. We're only packaging food but the high speed lines are 45-72 pouches/min.
I would have simplified the design. Whish would have fewer parts and mechanical parts.
Prusa seems like a cool company but I can't make myself pay 1000 bucks for a printer that bambu makes for 500
Nice videojet printer
Someone explain to me how that printer printed a label into the bag from range?
Pacman: suffering from success
This is the kind of automation that's good.
Toss in an oversized screw and see how many times the batch with it gets recycled until they notice.
The bigger screw would never go through the feeder hence never trigger the weight check
Buddy works in a warehouse and has one of these machines from the 70s that is a quarter of the size and twice as fast...
Czech repuplic 🇨🇿
erm that trick isnt new at all. the screws are all the same wheigt so using a scale is the fastest way to ''count'' them.
You’d think this same technology could be used in pharmacies
STL please😉
Counting parts by hand is like half my job lol
Omg I want this! 😁
That's not the first I see. I wonder why why just can't weight screws. Of course we would have to pack a few more, just to be sure, but it seems to be more easy solution.
This machine does that. Buckets are roughly the right size per pack. After filling the bucket is weighed. If the weight is wrong it just dumps the whole bucket and starts again. Likely this is more efficient that wasting time building something to dispense 1 screw into a bucket, or a way of removing a variable number of screws.
The easiest solution is to watch the whole video before commenting
That is really cool, but the single-use plastics are kinda disappointing.
That’s how bullet feeders work.
I just built the MMU3 and it was both frustrating/tedious but also crazy engineering and all printed support free. So far it's working great too
How meny lost ther job .. becaus of this fast robot.. And or.. are the baags with screening and nuts now cheaper
Unfortunately this seems like a maitinence hell
Prusa seems like a Charlies Chocolate factory for adults.
Ok, someone decided to play infinifactory in real life...
Excess production capacity never hurt anyone
You know it’s good when it overproduced lol
People are right, when the need for more screws rises this machine will make damn sure they get as much screws as they need!
when you only have a hammer, everything shall be a nail!
What are they using for the label printing?
Suffering from success
I would love to work there as an Engineer
Seems better than their printers 😂
Wild
Half the machine is printed 😂
Counting weight is still Counting
Out of the 100s of bolts and nuts in my m4 kit I think I was missing one 3x19 bolt which was suppose to be the 1 spare. Pretty impressive really .
I was also very impressed that they give you a spare nut or bolt for literally every part of the printer. No company does that, like ever. Probably one of the best products I’ve bought in the last few years from shipping, packaging, cust service, build instruction steps, FOS software and most importantly the printer itself. It printed perfectly first go and hasn’t stopped. Bambu labs proprietary can suck ma balls
The theme song of my divorce 😂
Wow they have their printers tuned SO WELL it is so cool how they 3d print their factory.
Is Prusa just a dudes garage 😭
single use plastics though, eugh
Can't even see the redstone
i wonder what the maintenance schedules are like...
Counts, weighs.....
czech labels shoved
packman 😆
Too fast, 😅
It is another stroke of brilliance in Prague.
Honestly, good that nobody has to do this anymore
Is this factory in czech republik because i saw czech words
It is!
I see basically anything that's not transparent or metal is 3d printed
It's neat, but metal is recyclable and worth something when stuff goes out of date. This is all useless trash once it's life has ended.
I think 3d printing is neat, but making MORE stuff out of plastic while we are simultaneously all told to stop using plastic bags, and to feel bad for using plastic is a bit weird to me.
Fastest thing prusa makes.
Prusa please don’t become Blackberry.
I loved my blackberry.
But I got used to a touchscreen and feel the screen real estate is more valuable these days now that touch input is much better.
As long as some better industry shifting tech dosen't show up, they seem to be in a good place to me.
They OBSESSED with the orange color.
Tbh orange IS basically the Work color
Idk why but i accepted IT aswell and Print Things that Work with orange
Still they missing to print there own haribo gummy bear
How awesome!!! 😁😁
That is not engineering, is design, that's exactly how your average food packaging machine works, they use the exact same essential parts, tumbler, funnels, heat seal, etc.
This is like if Scotch had their whole factory built out of duct tape. I love it!
Sounds more like prusa is too slow for that machine. Need to upgrade production!
It’s fast?
faster than a human, yes.. Wanna sea you do this labor by hand every 2 days a week.
Shut me down... machines making machines...
No one counts screws. Every company weights there parts. This is nothing new. Hell, I worked for a plastic company and everything was just weight it and the number comes up on how many of the product and that was long time ago about 20 years ago.
Prusa stopped counting screws 10 years ago
It's "proo-s-a" not "proo-sha"
For the longest time I thought Prusa was just a guy
Josef's just zis guy, ya know?
I love how you can see banding on the 3D printed parts 😂. My first prusa printer was a nightmare experience. It never even printed a single boat. I now happily use and run a business with a bamboo labs P1S.
Looks like you never learned how to assemble and use the printer, because they have thousands around the world.
In the end, the P1S is for right for you, and that's okay.
because for these mechanical parts you dont need precision, you can print them at large layer height to save time
and i have prusa and it prints perfectly
😂DOPE
In almost every kit I ordered from Prusa, parts were missing. In most cases the spare bag solves the problem.
So that's why out of 3 Mini+s I built, none had all the correct screws in all the correct packets lol
I truly believe the "Spare" bag is there to account for their own ineptitude at packaging the right amount of screws, not in case you happen to lose a screw or sth
I dislike their Lego kinda packaging style anyways, I'd rather they just sorted all the screws by type instead. The plastic parts can stay the way they are currently though, they're fine.
знаю я такие станки, насыпят лишнего и недосыпят важного, а ты из этого собирай😂
This is really cool. Is it a Prusa original design?
Yes
We need this at Intel instead of bins of screws and stuff. Every time I need screws for something I could tell it what I need amd it would give me a little bag of screws. Currently we have to just find the right bin.
They need to make thier printers cheaper if they only need to turn it on every few days they could be making but loads more money
I think they should focus on design 3d printer, not the packaging machine which can be easily find on the market
Prusa - fix seam issue in Prusa Mini with Input Shaper rather than playing with screws. Bambu next time!
Sounds like you don't know how to use PrusaSlicer, and bambu use PS for their slicer.
Oh, you thought the Slicer team just dropped everything and went to design and make this machine, silly you :))
@@fofopads4450 it is Prusa Mini new firmware issue.
@@eXe09 Silly you that you thought that I thought like that
Very bad design. Could be 1/10th the size if i designed it. Actually I've seen bolt and nut automation 3d printed files online for free that are much smaller than this lol 😆
Whether it is good or bad design depends upon the goals and constraints. Saving size might be important if you're space limited, but it might be harder to see where any issues may lie and slower to take apart and fix. If money is no object, there are expensive industrial machined that do this sort of thing but are often even bigger, might be less flexible. This looks like it would be relatively cheap to make and keep running, the design not being super compact may have saved a lot of design time and therefore cost to get the thing up and running and saving time, so giving them better return on investment. And when one has a working machine one can always make a v2 :)
