In this video, I experimented with two different VAWT designs. One works with the lift and the second is turned by the drag. Check out which one worked the best.

A. ABS will dissolve in acetone...get a jar...drop in some ABS filament (or ABS support/failed prints), dump in some acetone, put on the lid...wait 20~ min...it will create a slurry/paste of ABS/acetone...use that to glue ABS parts together...best glue for those types of prints bar none (just wait a little for the acetone to evaporate and you literally have a solid piece) B. ABS WILL degrade in the sunlight...paint the blades in UV resistant paint or they will get brittle C. That printer is stupid fast! Awesome! Keep em coming!!!!

ASA is a bit pricier but seems like a way better choice here - stronger adhesion, less prone to warping, 10x the UV resistance, and even though it prints hotter it's still well within the X-Max 3's temperature range.

That's pretty much ABS glue. It melts both pieces on the surface so when the acetone evaporates the pieces are bonded. Awesome hack

VAWT are not as efficient as HAWT but at small scale they are simpler and more convinient since they can use wind from almost any direction without needing extra components. The drag design is the less efficient of all of them but usually seems to spin faster on lower wind speed due to the extra material compared to the lift design

@@olafmarzocchi6194 that is incorrect! I have a 500W VAWT in my back yard. The tip reaches 3.5 metres tall on the pole. The unit is 1.5 metres tall. It regularly produces in excess of 200W output. That's a lot of Wattage to run a few 5 watt downlights

Of course it depends on the strength of the wind in your region. It also depends how often you get it. How much usable energy does it produce per year? Have you put a meter to get an actual estimate?
@Berkana

One thing that you can do is to combine the two turbines by putting a segment of the drag turbine on the middle shaft. Drag turbines self-start with much lower wind speeds, but lift turbines need higher relative speed of air across the blades to work. With a combined turbine, the drag turbine can help spin the turbine up to speed so the relative speed of the wind across the blades is fast enough for the lift based turbine to really work efficiently.

@@olafmarzocchi6194 this isn't correct. Darrieus turbines typically don't self-start, and they only reach their peak efficiency when they're already spinning above a certain rate. Drag based turbines self-start and can bring the Darrieus turbine up to its ideal speed. That's why there are turbines that combine the two.

I did some testing on VAWTs 4 years ago, similar concepts but my one using aerofoils had vertical aerofoils which allowed me to adjust the angle of attack to tune the lift for optimal running without having to calculate it with maths. I will say I agree the VAWTs can be very satisfying to watch

How much torque do they produce? What coil size and arrangement is your goal? Radial or Axial? At what RPM? When you begin to generate Current or Amps, you experience magnetic friction, also called cogging. The drag version requires designing the generator for the RPM range, most likely in the area of 1500-RPM max. The lift type will need consideration for over production, too high of an RPM, don't want to burn out your coils.

What would make it MUCH more efficient, is not using ABS :D... if you wanna use wind energy, you have to work really on a flat surface for the blades, if its ABS maybe you can brush epoxy on it or so, I didn't try it, but I was watching and thinking me into this topic a bit, and it was obvious logic, that every not flat area on the blades would create little vortexes, which takes a lot energy from the force which is going against the blades... Can't remember if in the videos I watched they really showed the comparison, the more I think about it, the more I wanna print it too xD Ah great, you linked the files... thx!

Don't get me wrong, great project and props to all the work you put in, but if I may ask: Why? What's your goal? These turbines have terrible efficiency (and low wind speed characteristics) compared to normal ones. If your actual goal is to eventually produce electricity, there is 0 reason to choose these over a normal wind turbine. They are cool no doubt and depending on personal taste you might even find them better looking than traditional wind turbines, but still: Why?

Better off looking at 3D printed RC plane wings. They already have the designs down for light weight strength. They don't foam fill them, they do single layer wall with LA PLA so it foams so even lighter all in vase mode and then they add cross beams on the inside to give it more strength. Then they jam carbon fiber rods to keep them straight. Once out the ones who go for extra strength then sand and then epoxy the wings making them even stronger.

Hey mate, very nice project. I love that you actually did build them quite big. Cannot imagine the work that went into this! Props to you. I noticed though a small error in the design of the first (lift based) turbine, that might hamper its efficency quite significantly: The airfoil is placed upside down / inside out. The suction side of the airfoil (longer side when looking at its cross section) should be on the outside. To me it appeared, that you had in on the inside facing the axis. Also when rebuilding, you could consider putting the rods closer to 1/3 of the airfoil (closer to the nose that to its tail), to reduce the loads on the structure. Let me know if I explained myself. But all in all very nice project and although you do not produce any electricity, I hope the running turbines help convincing some folks that renewable energy is quite nice. Cheers

I printed a VAWT turbine maybe just a little big bigger than yours (The "drag type" aka Ugrinsky type), used just skate bearings and 8mm rods for the build, used a NEMA 17 with high-ish ohm resistance on the coils for higher voltage output (thinner wire and more turns usually) and I was able to charge a 12v battery and drive some garden lights no problem, finding an optimal ratio gearing was kind of tricky, too high gearing and it wont spin in low wind, too low gearing and the voltage generated might not be enough for you use case even in high wind. Given we have a lots of wind and I eventually put it on a 4m pole. You need to elimate all kinds of friction on the turbine when it is this small, it should spin freely just by walking fast holding it infront of you. Even light up some LEDS if you run around with it in still weather! I printed my parts in PLA and found surprisingly that red PLA sucks and white or neutral PLA holds up way better in a storm. Using print setting with minimal infill and perimeters, I was able to print each segment of the turbine in just over 1h on a typical Prusa MK3. Bearings and rods for maybe 10 euros, such a fun project. It worked continously for over a year, with only minor repairs that could mostly be fixed by some super glue. Had to move and now I dont have a garden for doing these types of projects.

Hi. vawts are a bit more complicated than they first seem.. Well to give you a few guidelines the lift tipe needs to be started and your profile while it looks that will produce lift isnt realy optimal since in a rotation the aoa actualy changes the profile itself while you also have to think that every rotation at somepoint blade gets into aerodynamic stall which is problem by itself since you proobably know that stalls arent completely controled..also the efficient operating speed for smaller lift ones can be scary (they really have to go fast) on the other hand drag type turbines have rly bad efficiency compared to lift ones which just adds to the fact that even lift vawts are terribly inefficient.. yes vawts work with 360deg wind direction but in most cases it is not worth it.. for domestic use wind turbines are not rly a thing sice the size exponentialy makes it better(for simple physics).. there have been some attempts in design to make something usefull but for now windpower for homes is still a dream...
