The kickstart of this new direction was the design, build and testing of a functional portable wind turbine, here depicted. The nacelle interior was designed to be composed mostly of lightweight support structures where no moving pieces were used.
Here are depicted examples of the two prototyping technologies applied.Rachel rep
This process can create parts with much better resolution and was used in the making of every gear in the turbine. The various stages of sanding and priming of the printed parts.
A just-printed left and a roughly sanded propeller blade right. The blade had to printed standing and was almost too tall to fit in the RapMan. The anterior nacelle and its internal structures. The bearings shown here and then used on the tests were also printed from PVC as a workaround to a last-minute issue with the real ones.
The central portion of the nacelle with its three aligning channels and the sun gear, planet gears and carrier already assembled.
A comparison between the designed part and its prototyped counterpart. Pretty close. The posterior nacelle is shown here with the rudder and internal structures completely disassembled. The electric motor shown was the very one used on the tests. Propeller hub and blades. Different blades can be fitted on the same hub as to test different pitches and shapes.
The assembled propeller and the very noticeable pitch of the blades. Propeller hub assembled. Remeber the sanding and priming stages? We simulated various levels of wind using an industrial level blowing fan. A simple electronic circuit was put together to give us qualitative measurements of the turbine's output. The same circuit from the previous photo encased and ready for testing. Results after a evaluational-turned-destructive testing. At around RPM one of the blades, which had been broken and repaired beforehand, snapped in two.

Copyright Info. Made in NYC.Of all of the things to love about 3D printing, the ability to share complicated project builds that previously only existed as text-based instructions is definitely one of the best traits - particularly when experts from any number of career fields share projects that would otherwise take months to figure out on your own.
Andreas Haeuser, an aeronautical engineer based in Germany with over 25 years of experience, is one of these experts who has been spending many hours outside of his office designing and developing technical projects.
While he previously used more traditional manufacturing fabrication processes such as CNC milling machines and lathers, he has been using 3D printers for the last five years to bring his projects to life.
Transforming Wind Turbine Blade Mold Manufacturing with 3D Printing
Among the projects that Haeuser has been focusing on are energy-harvesting 3D printed wind turbines and 3D printed solar stirling engines, which are the result of two years of development, multiple prototypes, hundreds of test drives and numerous calculations and laboratory tests. Haeuser offers the projects for both the wind turbine and the solar stirling engine for sale on his Reprap-Windturbine websitewhich include the 3D printable files and detailed construction manuals that provide information on the theoretical fundamentals as well as step by step instructions with over color images that detail the construction process.
It's stormproof and robust. I get very good feedback for this project from all over the world.

People print it, build it and produce green energy with this. To exemplify this, he only uses open source and low cost kit-printers during his development process such as a Prusa I3 and a Mendelmax 1. While the wind turbine offers users a way to harvest energy from the passing breeze, the solar stirling engine works by heating and cooling air in a cycle. It was originally invented in by the Scottish clergyman Robert Stirling and is the second-oldest thermal engine invention after the steam engine.
While Haeuser notes that others have attempted to build a stirling engine using a 3D printer, no one has tried to build a low-temperature stirling engine for solar use. After 8 months of development, the project has culminated in a final design that - similar to the wind turbine - features a full-featured construction manual with images, historical information and detailed step-by-step building instructions and video tutorials. While his example model is a fully-functional stirling engine, it is too small to power in an amount that would make sense to use it.
However with some simple scaling of the 3D printed parts, a user could easily create a custom size depending on the amount of energy they want to harvest. Haeuser hopes that as 3D printers become both larger and cheaper, this will be made much easier in the near future.

Fun with 3D Printing. Printing Technology. Price Comparison. Rapid Prototyping. Harvest your own energy using 3D printed wind turbines and solar stirling engines. Higher efficient percent. To see a Imploturbocompressor animation, is possible on a simple way, just to check an Hurricane Satellite view, and is the same implo inflow way nature.
What a great science project. However, these would likely photodegrade into a pile of dust before ever generating the amount of energy used to create them.
However with some simple scaling of the 3D printed parts, a user could easily create a custom size depending on the amount of energy they want to harvest" This type of comment is so typical of a lot of the "green" energy movement. If it it is so simple to scale up to a useful generator, why didn't he just do it and prove its viability? If commercial wind energy is so good, why are subsidies necessary to set up this "free" energy.

WARNING: The theoretical maximum power of this turbine is 50watt however, the stepper motor used as a generator has low efficiency with measured maximum power around 20watt.

PayPal daniel. This fully functional wind turbine has been specifically design to be manufactured, assembled and operated at home with its unique 3d printable design. The PVP maintains an optimum power output through control of the turbines rotational speed.
Whilst optimising power output the PVP also protects the turbine from dangerous over speed conditions by limiting its maximum revolutions per minute in wind speeds greater than the design point. The turbine has been designed with flexibility and growth in mind with provisioning for a bigger generator and blade without alteration to the turbine architecture and major structural components generating more power for less investment in the future.
The turbines printed parts can be manufactured using less than meters of plastic making the cost per watt of power extremely competitive.

This is an awesome design! I feel like I am missing something, the parts list doesn't seem to have part numbers that can actually be ordered for all of the mechanical parts? I see the NEMA motor and some of the electronics in the Assembly Drawings but not things like the bearings and slip rings. Hello Daniel, Is it possible to get the inventor models for the parts where you use the printed bearing sleeves red parts in your drawings i would like to adjust your design so that you can place standard regular bal bearings in stead of the printed parts.
I found it really useful to have all the documentation together. Quantyti list and printing settings lists are very poor quality Cant see anything if i print it on A4 sheet.I am currently finishing a two year engineering course on wind turbine tech.
Amazingly i made an rpm reading of 80rpm on my turbine with which i was well pleased If not dont frete i have uploaded the screen shots i used in a. Good Luck! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson. Open a new part on solidworks. To achieve an accurate outline shape of a turbine blade a good cheat was to import a profile drawing of one into the solidworks sketch then sketch over it tracing its curves using splines and lines.
Insert the picture, using the property manager reduce or enlarge the picture to what ever size you deem necessary, i chose about 3 inches as it was just about the right size for the 3d printer remembering that this is only the radius, the over all diameter will be just over 6 inches.
Trace over the out line at each end of the blade with a vertical line. Next, we are going to divide the blade into 'stations' the reason will become clear later. Where the vertical lines cross the outline of the blade insert sketch points. Now using lines, arcs or splines trace over the outside of the picture using the points as joints, then delete the picture you inserted to reveal the outline sketch of your blade, do this in the side panel.
Selecting each plane add a sketch. The sketch on plane 1 will simply consist of a semi-circle to reflect it being the root end of the blade that attaches to the turbine Hub.
Vertical Axis Wind Turbine
The other sketches along planes 2 - 7 will have one side flat and the other curved similar to an aeroplane wing reflecting the required shape for the aero dynamics, if you were standing infront of a turbine watching it turn it is this front face of the turbine you would be looking at. The straighter of the two long lines we traced from the photo is called the leading edge, when the turnine is rotating it is this edge which will be breaking the air as it rotatesIt is for this reason i will make it more round than the trailing endge on the other side.
I used spline lines with around 4 points to each, making them easier to manipulate to the desired shape and curve. Just like the previous step select each of the planes to insert the curves in seperate sketches. This time the curves will be more pronounced to reflect the aerodynamic shape of the blade. Now using 'Surfaces' select 'Surface Loft' and in 'Profiles' select the splines on the top side starting with the semi circle at the root moving out towards the tip making sure to select them in order.
Using 'Planer Surface' and selecting the two lines seal off each end of the blade like below. Now we want to join the two long surfaces and the two 'Planer Surfaces' we just created together, we accomplish this by using 'Surface Knit' and selecting Try to Form a Solid If you have been successful when the blade is cut into two sections it shou;d be clear to see the inside is no longer hollow but a solid, this will be necessary for 3d printing later.
Just finish the blade tip off by using 'Features' - 'Dome' and select the face end of the tip, adjust the length to your own preference 0. Thats the blade complete, the next few steps invole drawing the hub and a suitable tower, if you like you can draw them as seperate parts and join them in an assembly file which was what i did for printing however for the purposes of this lesson i will draw the hub here in the same drawing.Portable solar power has already taken off, but what about when the sun goes down?

Poznan, Poland-based 3D printer manufacturer Omni3d has developed a 3D-printed, foldable wind turbine that can generate up to W of clean electricity — enough to power multiple smartphones, laptops, lightbulbs and other small appliances. The team is making the design database open source so anyone around the world can easily build it with the goal of providing clean electricity to poor areas off the grid. The wind turbine is lightweight and can easily be moved whenever the wind changes if you power it from a home outlet or battery pack — from the garden to the balcony to the roof.
They are one of the solutions we found at actual energetical and ecologial problems we have to deal with. The second one is that more and more Fab labs are created. These places allow everyone to realise self-designed objects. Based on these two facts, we defined the subject of our project: the design and test of a 3D-printed horizontal axis windturbine.
The printer that we used is a Up Mini.
We chose this printer because it has a good precision of printing and uses a thermoplastic, the ABS. The ABS possesses better mechanical properties than the others thermoplastics available on the other printers. The ABS is more ductile and more resistant.
The main constraint we will have to deal with with this printer is the maximum size of the pieces to print. Indeed, the printing volume of the Up Mini is of x x mm. The generator that we chose is a Maxon EC This generator is followed by a gearhead that allowed to increase the permitted maximum admission torque to 1. It also enables some admission rotational speeds that are consistent with those of the hub untill An encoder connected to the generator allows to know at every moment its rotational speed.
Due to the printer choice, we were forced to create blades in several pieces. We decided to design two sets of blades. The first one has a 70cm diameter and blades are formed of 3 pieces. The second one possesses a cm diameter and blades are made of 4 pieces see picture of assembly.
To determine the shape of these blades, we used a matlab program that gives the form and the twist of the profiles as function of the radius. This matlab program takes as arguments: the type of profile used, the design wind speed, the design tip speed ratio and the desired rotor radius for more details: see master's thesis. The hub has two main functions: to assure the blades position avoiding any rotation or unhooking of those, to transmit the torque to the generator. In our project, the different blades foots placed together form a cylinder.
This one is then covered by the two parts of the hub. We maintain the assembly fixed with nuts and bolts. The first part, the nose, possesses also an aerodynamic function.Commercial use is not allowed, you must attribute the creator, you may remix this work and the remixed work should be made available under this license.

It does not work in the wind. In very strong wind it can spin but then it turns in the wrong direction. Is it possible to obtain the modifiable CAD files e.Apple id login attempt history
Solidworks part files to explore this design? Thank you. Printed this on my small M3D printer. Just need some wind around here to see how it works at this size. OK so you made a generator sized cylindrical space to put a generator and just don't have it hooked up to anything, I take it.
That is excellent! Probably the thing to do is to put a small hobby DC motor, running backwards as a DC generator, and mechanically make adapters for the body and the shaft.
Then two wires run down the stand to our electronic, and there you have it - wind powered electrocoagulation water purification! I will keep this plan in mind for future work have a milestone to meet in 5 weeks or so first. I'm bad with electronics so I have no idea, but the idea is that the generator part of the stand would house a stepper motor not currently designed for it and the motion would put a small charge in a batter that you could then use to power your cellphone or other devices.
However a few challenges need to be solved first including: -Battery Solution -Determining what scale vs. There are commercial products available that do a similar thing so i don't see why we wouldn't be able to.
I think we're even capable of creating lighter, more efficient versions by printing hollow and iterating the design over time. Hi, is there any provision for hooking this thing up to a DC motor to generate a small amount of power with it? Really like the design.
Printed it up and assembled it with no glue. Bearings fit with no sanding or filing. Thanks Much. Rich Tech. Design is!!
