This time I fully 3D printed a shredder, there were challenges, mainly because I had to use plastic. But still, I managed to get a reasonable result out of this machine, and well it did work, as u see in the video.

I respect that he shows it in action and doesn't cut off right before it happens and talks 20 minutes of BS before he finally shows it uncut. +respect
More details about the CAD process would make this twice as interesting. More actually. We've all hammered together and partly broken poorly toleranced parts, but describing the design process that ends up with a well manufactured product would be invaluable! Love your videos
The small gaps are probably from the pieces deforming from the hammer head strikes. You should use a striking plate between the piece and the hammer to spread the force as much as possible.
No, the hammer is compressing, not expanding.
You would have gapes but would still fit.
I've thought about this (a 3D printed PLA shredder) several times and always kind of blew it off as ridiculous, but this video turned me around. I wouldn't mind seeing this fleshed out with a sturdier gear box and perhaps metal teeth inserts. As it is, I'm very impressed. Excellent work.
Inserts? Naw dawg try sacrificial (?) loss casting where the PLA objects serve as moulds for casting hardened alloy teeth
@@yourt00bz why go through that much effort? You can cut and file aluminum plate with woodworking tools, following a template that is either printed on paper or 3D printed (depending on the cutting method you plan to use)
@@RichardBetel because if it can be cut with woodworking tools then it is not hard or dense enough to crush heavier duty objects
and a wider heith difference between the teeths on each side. the deeper the teeth bite, the better it bites.
Same here, want to mount one of these in a tub next to my compost
It hurts seeing how you hammer those blades on tube. You should have put gear on the wise and hammered tube through some wood. It insures nothing is skewed and you do not damage any surfaces.
Even THAT IDEA is painful... MILD SOAP & WARM WATER as lubricant IS ALL HE NEEDED!!!! Sometimes the SIMPLEST THINGS are forgotten by the most BRILLIANT MINDS...
maybe if you freeze the axle
@@flojotube9323 Bro your comment is painful to read, who tf still types in all caps? You sound like my boss & she's a bitch so.
@@flojotube9323 why ALL the RANDOM capitalization
No all you wrong. You should use saliva and ice. Wrap it in tinfoil for 6 minutes.
pro tip: put the aluminum square tubes in the freezer for a couple hours so they shrink just a little bit, it'll make it easier to get the shredder wheels on. and like other commenters have said, put something between the hammer and the printed parts to better distribute the force, or use a rubber mallet if you have one.
Using these for aluminium casting would be a great start to getting some real shredder performance
CRAZY!!, I LOVE it. Your dedication is amazing, keep it up.
Sweet animation Mate! I know how long that takes (I'm learning with my son). I really love seeing what you come up with using your printers and brain, awesome work. 👍
Nice! What about adding metal blades to the shredding wheels? It would still be mostly 3D printed and get closer to the results you want.
May be carbide inserts...
Also, the speed of both rotors should be different, so it just does not fly through. It should solve the problem of not really shredding the sturdier parts.
A splash guard is indicated. Than more teeth for shredder discs and if you can metal insert plates as cutting edges for less wear. And metal gears and at least 80% infill for the gearbox housing.
Great project! Thanks for sharing!
I don’t need one, but want one! Very honest video. I like your style 👍🏻
You have inspired me to get into the hobby.
I ordered an adventure 3 pro last night. It’s a cheap budget machine but I’m looking forward to getting into this and I hope to maybe evolve into designing and doing projects like this.
Good work!
Thats definitely not a "cheap budget machine". A cheap budget machine would be something like an Ender 3. The Adventurer 3 Pro is a high quality printer that comes with quick change nozzles that are able to print Carbon Fiber Filaments. Print volume is pretty limited to basically 15x15x15cm which could become a problem if you want to make larger parts without having to glue them together. It even comes with a glass bed so adhesion should never be a problem because you dont even have to level it. It has auto filament loading. It has an HD cam built in, this way you can watch your prints online from whereever you are. Its basically silent when printing. It delivers great results in general IF you can get over the 15x15x15cm limit.
Definitely not a cheap budget machine. Do research before buying something. Also if you for some reason cant fit a 1KG spool of Filament into it, they sell an adapter for 4€ OR just tinker it together yourself and print it.
ONE THING TO CONSIDER IS: You can NOT fit regular nozzles into this machine. You have to buy a replacement for 35€ and 45€ from them. Thats quite scammy in my opinion. For that price you could buy 30 regular .4mm brass nozzles or 16 .4mm MK8 hardened steel nozzles.
I didn’t want to start with an ender 3, but not a Bambu Lab X1 that’s nearly 4 times the cost of the A3 pro. To say it’s a cheap machine is probably not accurate, but its certainly not unreasonable either.
I am aware of the nozzles, i wasn’t thrilled about it but it’s super simple change which is good because my kids will be using it.
I wasn’t concerned about the camera and Wi-Fi connectivity. I just wanted a super easy machine to start with that will print PLA and a few other higher temp materials.
If I want to do larger prints I’ll get a bigger machine with more print volume.
For now this will be a machine to learn on.
I am doing fusion 360 tutorials and already have some projects lined up for it.
Maybe I’ll do some videos on my journey.
Happy printing 😊
I'm quite interested in how this would work with shreding fabric, especially would it still work if the shredder teeth were more fine. I definitely did not think those plastic teeth would hold out at first, very impressive.
Looking at his results with the flat plastic pieces, it won’t do well as is, but I’m sure if you tighten the tolerances and maybe add sharp edge inserts of some sort, it would rawk.
@@RichardBetel It needs a more robust gear assembly and thinner cutter plates for sure.
Old steel brake rotors typically just get thrown in the trash but they could probably be cut into shredder discs using a plasma torch. Get an old gas powered wood chipper or lawn mower engine to power it and you can make a shredder out of mostly trashed items.
nice shredder, cool idea!
It's always fun seeing PLA do some work!
..a really interesting and fun way of learning mechanics....
and teach it to others perhapaps, i guss many kids will love this...
suggestions:
sychronisation and locking of the shedder axis to limit movement
the teeths can be made of thin strips(teet width) of metal that is shaped to fit (it is the part that trasfere the initial force)
drive both shredders simulanesly...not just one (to balance force and reduce wear signifficantly)
the gaps btween the induvidual shredders are faar to wide
the shedders do not need to fit as snuggly to the square aluminum bar as long as they can be locked and pushed together (u can easily do this by two parts screwed into eachother, when screwed out thay puch the parts together)
the base dont need to be as snuggly fitting to the shedders axis (thers no grinding here...its just for holding what ever u shredd in the shredder)
..ps.the reason the plasic wheels take so much damage is because they experiance a force from on point...doubble gears on opposite side of the gear will reduce it...but it also make the gear system more complex...
ex X-O-X (where both X are driving the O axis...spreading forces over two poins 180 deg from eachother..for even smother leveling, 3-gears 120 deg apart..
Would be interesting to see how different shredder materials perform, like carbon fibre filled nylon or polycarbonate.
Also it would be cool to see you integrate metal somehow, perhaps via lost PLA casting or something.
Or do the carbonfilled nylon and then electroplate it with the hardest metal you can find lol.
Perhaps make composite grinding teeth, just a carbonfibre filled nylon shell, filled with concrete (to be cheap) or some other cheap high compressive strength material and then electroplate it with the hardest material you can find lol.
Love these projects.
I think you're a madman and I love it.
Cool project. Worked better than I would have expected.
NGL, I was grinning ear to ear watching this. You, my friend, earned my sub.
Greatly appreciate your ideas and videos! Thank you!
I'm sure someone else has covered this, But the reason your shredder won't shred, is the gaps between cutting surfaces. the opposing teeth should almost touch as they pass one another, and the gap from one rotating assembly to the other should be very small as well.
The only thing you cannot currently account for is material weaknesses and flex. if you drop a hard object in, does it open the gap between both cut heads. your aluminum core is great but it doesn't stop the frame from allowing movement.
Improvements to this design could be making the frame from extruded aluminum like your 3d printers are made from, printing your gears from a harder material, or have PCB way make them.
Either way, fantastic video. I would hope you will revisit your designs with improvements in the future.
Rebrand this as a compost shredder, and you solve the issue of it not being able to shred hard things!
Great project!
when i was little i was obsessed with shredders and always wanted to 3d print one, this video is kinda a dream come true for me.
Really cool concept. 👍
perfect kitchen mashine
Fantastic work, dude! Really well done! 😃
My mother does compost... It would work great for her!
Anyway, stay safe there with your family! 🖖😊
Have you thought of using cast aluminum? Here on youtube, myfordboy has some really decent videos on using 3D printed parts and casting them in molten aluminum. The gears would likely need to be made of aluminum bronze for the increased wear resistance and strength, but the shredding teeth themselves could probably be made of cast aluminum and survive fairly well.
Maybe then you could shred aluminum beverage cans, PET plastic bottles, etc.
i think this is great, would work well in a food composing system
A new twist on a food processor. A problem with a typical food processor is that if you let it run too long, the contents become overly shredded, and you can easilly turn your onions to sludge instead of shredded onion. Your shredder does a pass, ONCE. If you put fine adjustment on your shredder, you might have a deterministic food processor where the first item through is the same as the last. Perfect sizing. Its like you are on the cusp of a new food processing machine.
love the non-traditional cider pressing
I put the plastic on to stop lube from flinging.
I left the shredder open to not prevent the debris from flinging as it fell, badly, into a cardboard box on my floor.
Hell yeah my guy 👍
Very good. Maybe a close loop control system will improve the efficiency, by running the motor in low speed but increasing tork when needed (but is much more complicated system, needs calibration, sensors, ...)
Now redesign it to mount a set of carbide inserts for the cutting edge.
very amazing. Good Job.
It looks like a great salad shredder. You just need to add a wood or cardboard shoot on top so the items stay in there the entire time instead of flying out. It would be cool if you put some sort of metal on the tips of the blades. Maybe something like a razor blade or some other cheap metal part attached at the blade tips. Good job. It may have slid on easier if you sanded the inside just a tiny bit, especially the corners and definitely use lubrication. Great build. I enjoyed the video.
Very nice project well done! There is a very clever chemistry hack that transmutes the plastic. If you coat the teeth with super glue and fixer spray, the plastic becomes super strong! And if it can then shred plastic, this machine can save a fortune!
a perfect compost bin shredder..
will saves weeks of natural breakdown
Great project...I liked the way it took 'bites' out of those apples. The tooth depth is just simply shallow enough, that it did not exceed the elastic limit of those fine sheets of plastic. they are just too flexible, to be broken with that little tooth depth. I agree, the transmission needs a little refinement, but, This would be perfect for making salads, it shreds lettuce and cabbage absolutely perfectly. I don't know if ABS and PLA are considered "food grade" or not.
Awesome work! Just wondering, did you think about using machinist inserts that could be screwed onto the faces of the cutting blades?
Yes. I had a very similar thought. Something like the carbide cutters for lathes. There's probably something that fits better that already exists in the market though. That's just the first thing that comes to mind.
Hi, you may freeze aluminum profile before installing plastic stuff install. Due to low temperature metal should shrink and you may easy install without using hammer. I used that technique with bearings and it is worked for me...
First video iv seen form you I love it, do you think if you had pcbway make you those parts in metal it would shred pla no issues? And how small would the pieces be like could you make a 3d print recycler out of it?
Love this
I would sacrifice the counter space just for the lettuce-cutting abilities. Good stuff.
best lettuce shredder ever
Have you thought about adding metal (carbide or something) tips to the teeth of the shredder. They can be replaced and reduce wear of the shredder parts. you could use just some metal squares screwed into the pla where the teeth would impact that way the metal would take most of the abuse, and as previously stated, could be replaced.
Awesome.. think you nailed the gear reduction. Now instead of will it leak, you can be will it cabbage?
🤣"Dry aged cheese burger" you made my day!
Great idea, maybe try adjusting the rollers to be thinner where there is no teeth, then have a solid piece there so that whatever part that is in there would need to be "grated" because there is a solid piece blocking it, i dont know the name for it but in your black PLA, imagine fingers that are solid that extend in about 75% in, at a 90 degree angle of the 2 shafts, the idea is to not allow pieces to be pulled in by the whole roller, but only pieces by the teeth, like many little nibblers. For your gears maybe try some harringbone gears, if you still have issues due to torque i know that people 3d printing RC cars use polycarbonate for their gears sometimes too. Love the idea though, I could see people using this for composting, or even pet food prep. Cheers!
Nice
Some herringbone gears might help with the slipping in the gear box
i like it. have you consider making a foundry for aluminium and use it with the 3d printed gears?
needs a hopper around it to keep stuff from flying out. it'd be good for shredding stuff for a compost bin.
I think the teeth need to pass each other further. The flat round radius next to the teeth radius could be smaller and the teeth radius bigger. I think that's how the big metal ones work so well, also a much slower gear ratio would help a lot with torque and grab opertunity too in my opinion. Too much speed means a lot more strife on the gears if it does jam. I love projects like this. Thanks!
1:21 all about that drip
10:50 herring bone gears could remedy the slipping
Very interesting project. Out of curiosity did you scale down a larger unit or just eyeball the aspect ratio of drum to tooth length on the shredder drums? Seems like longer teeth may help. I may have to build one at some point.
dude i love it
Great work! This is awesome! This could maybe be great for like a compost bin pre-processing machine. I don't know that shredding organic material before composting really speeds up the composting process, but if it does that'd be a great use.
Shredding organic matter makes a huge difference to composting. Not leafy stuff like the lettuce but the stalks, like brambles and twigs. The home shredder you can buy for $100 is a 10" diameter steel disk about 1/2" thick with a blade in a slot.
@@maverickstclare3756 that's really cool! Thanks for the info!
Amazing project, just wondering if this can shred failed prints. I am having plenty og failed prints in my printer. Planning to recycle them.
I think I understand that the pressure of the machine is what "cuts" or rather pressures the material that you feed in to be torn... but why not add blades metal blades at the end you can get from cheap shavers?
Foodshreder, one step closer food printer!! Cool i like the idea:)
Great design! I designed a shredder like from this but just smaller. I made a few videos on it but I’m still working on finishing the build video
for the hammering what about a steel pipe that fits over the central rod?
needs to be cut at a right angle and have slightly rounded edges.
Perhaps consider a two stage shredder (2nd assembly underneath) with a different tooth pitch to achieve finer results.. Im curious as to what infill you used to get this done..
This is so cool !! Also what are your slicer settings??
for this sort of things, you should have made an orbital gearbox instead. way stronger connections
Once you have the power transfer issue solved you will run into the problem of the cutters wearing quickly. In order for the cutters to last and cut well they need to be made from a harder material than what is being cut. When I was working in the recycling industry the cutters on our grinders were made of hardened tool steel with tungsten carbide cutting edges welded to the cutter ends. Those were used to cut aluminum and plastic, but were capable of cutting light gauge steel if necessary. I think that a decent solution that would allow the cutters to be 3-d printed would be to electroplate the cutters in nickel. That would provide enough surface hardness to keep the cutters from wearing when shredding plastics. You will need to adjust clearances to allow for the thickness of the electroplate.
Make a sacrificial piece to hammer on. Preferably from wood.
I've been wanting to do this for quite some time, except I plan on casting all these parts in metal.
Seems like one of those things you want to make with a slip coupling to save your gears, maybe a hammer style slip coupling to still make it shred a bit when it's stalled?
Otherwise very impressive performance and build.
Perfect for accelerating composting
You should add a clutch between the gears and the shredder to prevent shredding down the gears instead! 😉
Dude he could just change the shredders design to put indexable inserts into it. I am pretty sure it would work very good
Hello! What about your tank on 3d printer?) Thanks for the video.
You should use chevron gears and cut aluminum cans into strips and somehow attach those stripes to teeth surfaces, so you can shred harder things.
10:10 now that is rather optimistic.
what about adding a heavy flywheel?
what about electroplating the shredding part to make it harder?
I used metal shredder from paper Shredder. and a 3500lb winch motor to turn it. 3d printed mounts and framing to hold it all together. It will shread anything and torque 3/4 plywood reinforced by angle iron to 45 degrees should it jam.
Kinda reminds me of a Weima ZM series shredder. Two broaching knives to pull into the cutting might help.
If you didn't tap the burger, you'd never know it wasn't made 10 minutes ago.
Scary.
I would heat the aluminium bar just enough for the blade plastic to melt a little bit when inserting them. I would do one blade a the time and when all of them fit well, I let cool the aluminium before inserting all of them.
Very cool project that worked well in my opinion. Imagine using this to pulverize kitchen scraps for composting. Maybe add a domed lid to keep items from flying out. A lid doesn't make sense for this video as it would block the view!
I beg to differ, my friend. Your tank track design is awesomer! Still, fantastic design. You're clearly pushing fdm to it's limits.
I've always wanted a small shredder for cardboard and styrofoam to put in recycling.
You've heard of The Salad Shooter well now we have The Salad Shredder. You should try throwing some carrots, radishes and other veggies in there and see if you can chop up an entire family size salad in minutes.
Will be a good addition to next year apple juice pressing process :D
"Most interesting thing I have ever made"
"...Dad?"
That's a fun project ;) be advised that thing will eat you fingers if you are not carefull.
Attach metal blades on the leading edges of the shredding blades. The same way lathes work. More shredding ability and will save the edge of the shedding blades.
Awesome.
brilliant !!
Sooo .. it will shred a finger to the bone and then stop?
coolest 3D printed salad maker EVAH!! P=
Sweet! Hey, how about a toroidal impeller?
It would be interesting to put a current sensor on the motor hooked up to an arduino or circuit that automatically reverses the shredder for a short amount of time to clear jams.
I am impressed with the hard work you have done. I am not for sure if you are familiar with hydraulic press. It is a easy way to insert object in without hammering which result expanding the parts. From that the looks, it seems to be dangerous to operate the machine 🙂.
Mc Donald's dry aged cheeseburger :-D that made my day haha!
Cool!
