After building a DIY foundry to recycle the metal scrap from our DIY machine shop, we wanted to build a machine that can recycle our plastic scrap as well. We built SHREDII, a tiny yet very powerful DIY shredding device that recycles our 3D prints and other various plastics into small shreds that we can then use in INJEKTO 2.0. Our ultimate goal was to reduce the plastic waste we produce and the process was definitely very challenging.

    My way around this, is that for most of the small waste you can use a blender. I bought one from good will for a few bucks. It works well enough. However, with higher infill or thicker parts it isn't great. It could be a good interim until this shredder gets out.

  • @zerumsum1640
    @zerumsum1640 Жыл бұрын

    ok, so some suggestions from someone with millwright training here, take with a grain of salt but these may help a touch. First off, great work on the design, my main worry here is those standoffs will be a bit weak for that steel shaft coupler. The aluminum one should offer plenty of torque, while also helping with any shaft misalignment and providing a place for torque to go if the shredder ever jams. Think of it as a sacrificial part like a shaft key, as it's probably easier to source another coupler than a new shaft, motor, gearbox, or blades. This will be important if you ever want to try aluminum or other softer metals in the shredder, as having that thing bind up could grenade that gearbox or burn out your stepper. secondly, if you haven't, it may be worth it to try hardening the blades, then tempering them. There's a lot of videos on how to do this, and one of those 3d printed foundaries you made should be able to get up to temperature, but word of advice: if quenching with oil be extremely careful of flare ups. I've had a quench tank throw 4 feet of fire on me before because tom the 200 lb shop monkey decided to put some light oil in there thinking it was a dump tank. i'm glad i was wearing safety goggles, and remembered not to gasp at the fire in my face, because i had no facial hair for a while after that. after hardening you can temper the steel using a regular oven. If you take the time to sand down the cutting faces to have sharp, 90 degree corners on the edges that cut before hardening you'll also make the motor's job easier. Plus, then you can use this to shred softer metals for use in the foundary. Third, as a safety, convinience, and quality of life thing, I'd suggest building a stand, feed chute, and catch bin for the shreds. wood would work well for that, and save you some time/cash on materials. the reason for the feed chute is to keep things from flying out of the shredder, and with a chute you can pop a bunch of stuff in at once. the chute should also be longer than your arm is, because even that little shredder will turn your hand into ground beef if you don't have a real fast way to remove power from it that can be activated with one hand. I had a co-worker who lost fingers to an industrial shredder because he was faffing about testing it and had the feed chute off while doing repairs. a moment's inattention and suddenly he was in too much pain to locate the emergency shut off button. Don't pull a dave, he's constantly throwing up a shaka whenever he waves as he's missing all but the thumb and pinky on that hand. As for the catch bin, that's just there to make your life easier. just have a few bins for the various materials (could even just use rubbermaid containers or something like that here) so whenever you need to mold a part you can just grab the bin instead of having to set up the shredder. personally i'd run down to a kitchen supply shop and get some camwear food storage containers with lids, but that's just cause they are some reasonably tough clear containers, and the lids are pretty good at staying on unlike some of the junk you can find at walmart. depending on your printer's size you could even print some containers, but they'd probably not be clear. Lastly I cannot recommend some kind of e-stop or dead man's switch on this, as i said earlier a shredder will turn people parts into mincemeat with ease, and even one as small as yours probably has the torque to chew through bone. All industrial shredders require an e-stop or dead man's switch in the safety regs, and all safety regulations are written in blood. People have died to these things before, and running a hand or appendage through a shredder is an excellent way to require amputations. There's no way to save a hand/finger/etc that's been messed up by a shredder, and any clothing that catches in that thing WILL pull you into it. I watched a guy's tie almost drag him face first into a thickness planer because he wasn't paying attention around the woodshop, I'd hate to hear about an accident with this thing, and homebuilt tools like this still need the safety features as you're still taking the same risks running the thing. Remember: that thing will destroy anything put in it and it's gonna hurt the entire time it's happening. this thing doesn't run very fast, so it's gonna hurt. A lot.

    You missed one advice. They should have a punch plate on the grinder with whatever size holes their injection machine needs. Allows thicker cutting plates with less parts to break while all output will still be the required maximum size.

    Yes! I have worked along plastic grinders, and they are unforgiving! These things will grind up anything that drops into them, tools also. I once saw a lady drop her whole purse into a grinder, (don’t know how she did it) and there were only shreds left. Our protocol was to always unplug the grinder if you were cleaning, clearing a jam, or doing any work on it. It definitely needs a prominent E-stop.

  • @ClappedOut
    @ClappedOut2 жыл бұрын

    The idea with the aluminum shaft coupler is that it uses a flexure to hold on to the shaft which is much stiffer and stronger than a set screw. Also, it allows for a bit of axial misalignment because otherwise any misalignment will force the shaft to flex at every turn and makes it harder to spin.

Over and over again I see people using solid shaft couplers, unfortunately it's not like it's something that's taught, you'd never know unless someone tells you. You should never solidly connect shafts unless you have the necessity and capability of having micron level precision in all your assembly. Just like the softer shaft set key that shears in the event of an overload.

    you may want to keep the aluminum coupler or make one that is weak enough so it would fail before the motor does because should the machine become overloaded by something too hard to shred you wont burn out the motor or more over the controller. you may want to build some kind of box on top so you can feed stuff in safely because there is nothing stopping the blades from tearing up a hand that gets in the way.

    I like your shreddy design, the One thing I'd change is to do what the majority of commercial shredders do, mirroring the orientation of the teeth at the halfway point, so that if you were adding them on one rotation point clockwise each time, once you're through half, add the rest on one point counter-clockwise from the last instead. Basically, you want your teeth to converge towards the middle as they rotate so that you have an area with concentrated force.

    Having worked in injection molding for years, I can add a few tips here for shredding. Be sure when you are grinding bottles, to pull off the label, and also the small cap ring if you wish to reuse the plastic. Also make sure your bottles are clean, and that there is no dust or wood shavings or any other particles on the surface your shreds fall onto. You do not want any contamination in your regrind that would show up in your project. Try to grind the same kind of plastic in one grinding, and clean the grinder teeth after each type of plastic is ground. Some plastics will not mix with others, and it’s the same with colors. If you don’t care about the color of the extruded plastic, colors can be mixed, but if you want a dedicated color, try not to cross contaminate. Using 100% regrind is not really recommended. It can cause balling up of the material in the plunger or screw feed. Try to mix at least 30% virgin into the regrind. Plastic does degrade over time. HDPE and LDPE is not so bad, and can be used for quite a while, as long as not overly contaminated. Some specialty plastics lose integrity the more often they are heated. You can also add color concentrate pellets or dyes to the clear plastic if you want a specific color, and you should be able to find those at a mill supply store.

    @@Atlessa bottle caps are usually LDPE, and actually are a more durable plastic than the PTFE or PET the bottles are constructed from. The advantage with bottle caps are that the colors are usually uniform. You do have to pull out the little seal that they put in some of the caps.

    Hey, Amazing Idea guys, and extremely well-executed, I'm one of the people who commented on the suggestion of using a plastic bottles (PET bottles) in the last video and I must say I'm impressed although I have a few suggestions as well, they are as follows: 1. Make a transparent top cover out of acrylic or plexiglass, mainly for protection from projectiles, and secondly to act as a hopper to shred material in bulk. 2. I think you might already know but still I would like to mention to not mix 2 different plastics together as they might degrade the performance of the material (eg: bottle cap and the bottle both are usually made of different materials hence their melting temperature would also be different) so just for ease shred and store plastics in different containers. 3. Just an addon to point 2, even 3D printing PLA might have different compositions and stuff so shred the same brand of plastic together. 4. you can use the aluminum shaft coupler for this purpose as the torque will be within tolerance (at least for plastics) and would be recommended as it would rectify any misalignment issues. for metal shedding, you can proceed with the custom coupler. Well apart from all these recommendations the project is pristine, and the quality of both the video and the product was outstanding I can make out these things are made to last so kudos for that. Overall the best looking forward to the SHREDII V3. Love from INDIA 😊👍

    Might be a good Idea to add a mech under the shredder to controll the chip Size. Stepper online also has real Servo Motors available. The downside of using Steppers is that they only have good Torque at low RPM. If you Chose a real servo Motor (which is Controlled exactly Like a Stepper) you get way More torque at Higher RPM thus using your 50/1 Reduktion gearbox More efficiently.
