    The creator of APC props was a RC plane guy at my club in the 90’s. We all were part of his product testing efforts fun times. He made them in his garage using a resin molding process. The 3D printed stuff today is really just proof of concept and mold making blank capability of which we didn’t have in the 90’s. The zip line prop concept should generate just as much thrust as a similar surface area standard prop as long as turbulence from the leading blade isn’t affecting the trailing blade. I will say that the foil shape at the root of the blade was found to have a large impact on the prop performance at various RPMs. The blade tip also can affect performance especially if the blade flexes under load. The APC props have a unique root foil and rigidity for a reason. Each prop use / profile be it Pylon Racing, aerobatics, general sport flying evolved into a unique foil design due to the performance differences and speeds the aircraft we’re running at. Drone props are massively ripped off designs in many ways to each other by the typical Chinese manufacturer. I haven’t really seen any drone props that are really engineered to a level we see with Zipline based in California or even what we did in the 90’s with our club member who created APC props in California 😆. Is there a need for real foil design in drone props? Oh heck YES!!! The trash I see being run today on drones is like our wood hand carved props we flew way back in the day😆.

    That's very interesting, and I'm sure it would have been a cool experience! 3D printing really is just a great proof of concept/prototype medium with some limited production uses. Makes a lot of sense. Most of our fpv drone props are extremely flexible (with the exception of our cinelifters) which is great for crashing, but I'm sure it is also a tradeoff in performance. I'll have to look into the APC props a little more. Thank you for the detailed explanation, it's really helpful 🤘🏼 Lol, this is so true. The copy and paste method of manufacturing is getting out of hand 😅 I'd love to see this become more mainstream. You've sparked my curiosity and I'm definitely digging into this soon.

  • @slickfast

    PLA is not the weakest. It's stronger than PETG and ABS. The reason people like PETG is for durability, which is quantified by the Izod notch toughness test. The issue you're really running into with the orientation you're using though is inter-layer adhesion. FDM prints are highly anisotropic, which means different material properties in different directions. I'd recommend SLA printing for prop prototypes as they are far closer to isotropic. They're also far higher resolution to capture the propeller airfoil most accurately. Good luck

    The second it started printing up I knew this would be an issue. Granted lying down it would have lots of supports but on it's side you should be able to get only supports on the very edges of the blades and that's much eaiser to fix/sand. Also nothing stopping him splitting the design into 2 or three parts that lock together reducing the supports even further.

    My initial thoughts (after designing, printing, testing, iterate) is that you are printing with stacked layer being normal to the axis of rotation. Hence the instantaneous destruction or RUD (Rapid Unplanned Destruction). You realize this at about 3 minutes into the video. I printed both the TriLobe and DuoLobe (3 blades and 2 blades) for a DJI Mini laying flat, slowly, 0.12mm layer height, without supports (sliced with both Cura 5.3.1 and Prusa 2.4.0-alpah-alpha6). I tried PLA, PLA+, PLA+CarbonFiber, ABS, and NinjaFlex (TPU). PLA+ worked best for me.

    I've printed quite a lot of props and found Tough PLA to be the best option, printed flat. Also, bigger (8" in my case) props work better as they rotate slower, reducing the centripetal force. Unfortunately, printed props always seem to be noisier and less efficient even if you work hard to sand & smooth the surface. While it's cheating a bit, my attempt at the zip-line prop used a pair of decent Carbon Fibre props with one blade cut off, stacked with the stem of the counterbalance sandwiched inbetween. You can buy hubs with a female thread - then use a long screw to hold it all together, along with some glue to fix the positions. For 8" diameter, I spaced the two bladed 10mm apart with a 30 degree angle between the blades. This seemed to give the lowest perceived noise level with decent efficiency. Even still, silent it was not.

    Can you try offsetting the outersurface of the prop by about 0.3mm and then fiber glass? Use carbon or glass toe around the hub. The aerodynamic centre of the zipline prop force is not centred on the hub which causes vibrations and twisting of drone arms. I would be interested in finding out what happens with a similar three blade prop with the props at 95.5, 124.9, and 139.6 degrees (these are prime ratios which I think will spread out the frequency of excitation. You get fewer repeating patterns with prime numbers with the rotation of the blades if that make sense. If you know what a response spectrum is, it flattens out the response spectrum). Each prop can be a different size so the aerodynamic centre of force is at the hub which also reduces vibration. Stag the heights of the props for clean air. I am really curious to see what the result would be.

    Assuming you have the AMS accessory for your X1, you should go for that dissolvable support you were talking about. You don't have to print the entire support in it, just the "interface". You may not even need to put it in water, it should separate more cleanly from PETG than using PETG support material exclusively. As for molding, you could make resin molds with silicone, OR you could use an mSLA printer to print injection molds and build a little DIY injection molding machine from a couple drill presses and simple electronics.

    If you want to do injection molding you can 3d print a mold. Use the high temperature stuff and print 100% infill then use lower temp plastic to injection mold. For an injector it is fairly easy to make one from low cost steel pipe. Make a plunger and a nozzle then use an Induction heater to heat the steel pipe. It will take some trial and error to get the temp right but you can easily and cheaply do it

    Re: Injection molding. You can make limited-use injection molds for some lower-temp thermoplastics on a resin printer using special high-temp resins. You would still have to make an injector, but the resin and collars for printed molds are both sold at reasonable prices for people who want low-volume manufacture that's too much to be entirely 3D printed but not economically viable to have actual dies cut from steel or aluminum. If you do end up exploring this, have fun with it!

The surface finish was good and they were almost balanced right of the print plate. So far they have managed to slowly ramp up to 23 000 rpm before exploding. I haven't tested the thrust yet but will soon. Just going off how much air they are blowing compared to regular props I assume it would be possible to fly on them but would need, on my 5" fpv quad, a throttle stop at about 70%. Maybe soon I will flight test them.

    You need a X1-Carbon Combo. If you printed them laying flat to align with layers optionally out of PETG with PLA as the support interface it would give you a support that would breakaway cleanly and give you a much stronger part. After prototyping the concept use either PA12-CF or PET-CF with Bambu Lab breakaway support material ("Support G") if necessary. I find using 3 interface layers with a grid like pattern with the carbon fiber reinforce nylon blends you really don't even need the specialized support material. It comes off extremely clean. Your printer and material choices will make a huge difference in your success...I promise you that!!

    Could you not use off the shelf props, cut off and epoxied into a 3d printed hub? Or do the blades need to be shaped totally differently from standard ones? As others have said, the approach where you use 3d printing to make a mold might be the strongest option.

    Could make a channel inside the props, shove a metal wire coated in epoxy in there. The metal wire will hold it together better, and the epoxy will slightly shrink (and mate the two materials together). Additionally, you could get a slightly conductive filament and electroplate something onto it. (Might have luck resin printing a micro lattice, for lots of surface area for the electroplating to deposit material on. Would have to be sparse unless using a electroless plating solution.)

    If we picture the Zipline-prop as a single unit being used in a tractor configuration so that one of the two offset blades is first being forward, does it matter which is advanced and which is trailing? This may be a stupid question but, when geese fly in V formation the trailing bird must be above to catch the pressure wave from it's leading bird. I imagine the second blade of the prop should trail behind to catch the wave to amplify the thrust, but if it does will this alter the acoustics or the performance?

    For strength it’d probably be better to print in something that melts with ISO and fume smooth the outside which would not only make it more aerodynamic but would eliminate layer lines on the outside. It may even be beneficial to anneal the props then fume smooth after that.

    ​​​​​​​@@CliffKajun awesome! I really like sunlu nylon like resin. It's got a lot of flex to it. It can be a little bit challenging to print with since it's consistency while printing is pretty stretchy. But for something like this where it's small and there's not a lot of stress on the material while printing it would probably be perfect. The nylon (pa) like can be hard to come by so an abs like is a good alternative (I like the sunlu abs like) Just for the love of God don't use a standard resin like elegoo grey or something. They are way too brittle. You're going to need something a bit more specialized

    I was hoping someone mentioned this. I've been effectively 3d printing and using parts for professional projects since 2000, and although most of that time was utilizing FDM, I knew it was a deadend(layer weakness and detail/finish). The main reasons SLA was not utilized was a combo of price/availability and material quality. Not only has the price of it all plummeted in recent years, the materials have also come a long way. I now mostly use an Elegoo machine and water soluble resin, much easier to deal with than the alcohol stuff, but some of the more exotic and stronger resins are still alcohol based. You may need to try a few to find the best resin for this use, but if you do you may never go back to FDM. Especially if you can manage to print with little to no support structure, tricky but do-able, and produces the best 3d parts I've seen in decades.

    PLA is in fact among the stro gest philament, its not tough, thats what you tought you had an issue with. As PLA has higher tensile strength, than PETG or ABS. However the issue was the isotropic quality of FDM prints (aka. weak along layer lines). If you. have issue with that i recommend high hardness grade TPU. If you cannot print it in proper orientation that is.

  • @CliffKajun

    @CliffKajun

    Жыл бұрын

    Yea, PLA is stronger, but not as flexible as the PETG. The start and stop of the props seems to be the majority of the stress and this is where flex is better. I thought about TPU but haven't found one that is hard enough to keep its shape at speed. Any recommendations?

  • @EcoMouseChannel
    @EcoMouseChannel Жыл бұрын

    The obvious solution is to use SLA resin 3D printing. You can get much better stiffness vs flex properties with resins like Siraya Tech Blu etc. Secondly... if you want to knock out batches and batches of these things, you really ought to get into simple mold and casting techniques. This is where 3D printing obviously shines, especially resin printing. Due to the smooth, almost non-existent layer lines. Casting is super easy, and not expensive at all, using Smooth-On products. Plus, there's awesome casting resins that harden in minutes. With a silicone mould in your drone kits, you could literally make new props in the field and be back flying well under an hour.

    If you want to quickly strengthen a PLA print, you can brush it with runny superglue, then spritz it with hardening accelerant, and the glue will go into the voids and pores, and your prints will be instantly far stronger.

    For better sheer strength, consider metal reinforcement. Extra light aluminum strip just inside the outer rim of the blade, creating a tension pulling inwards along the whole prop. Cheap, light, solid, reusable. Its the method I do for anything that needs to hold any sort of weight, because 3d prints are notorious with sheer because of the layering
