    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.

    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

  • @wombatillo

    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.

    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.

    Would be interesting to see how different shredder materials perform, like carbon fibre filled nylon or polycarbonate.

    Or do the carbonfilled nylon and then electroplate it with the hardest metal you can find lol.

    ..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..

    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.

    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.

    Good work!

    • @Sharpless2
      @Sharpless2 Рік тому

      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.

    • @KnoxGTX
      @KnoxGTX Рік тому +1

      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 😊

    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.

    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.

    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!

    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!

    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.

    Nice
    Some herringbone gears might help with the slipping in the gear box

    Hello! What about your tank on 3d printer?) Thanks for the video.

    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 been wanting to do this for quite some time, except I plan on casting all these parts in metal.

    Try and print a larger centrifugal pump and use a brushed washing machine motor, they are insanely strong and fast and run off of over 12 volts (way way over)

    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.

    needs a hopper around it to keep stuff from flying out. it'd be good for shredding stuff for a compost bin.
