You can choose from two main configurations: HAWT and VAWT , by using non-printed materials (like PVC pipe blades), fully printed PLA / ABS parts or a combination of both as you can see in the video below. Using 'Planer Surface' and selecting the two lines seal off each end of the blade like below. Our aim is it to print blades for a wind turbine with 2m in diameter and a power of about 200W. Description This is a 3D model of NREL 3 Blades 5MW wind turbine. Short glass fibers from scrap turbine blades are reclaimed and mixed with polylactic acid (PLA) through a double extrusion process to produce composite feedstock with recycled glass fibers for fused filament fabrication (FFF) 3D printing. I used spline lines with around 4 points to each, making them easier to manipulate to the desired shape and curve. Image credit: GE. advanced innovation. This attempt would prove the … Next use 'Features & 'Extrude Boss/Base' in both directions. Weatherization and Intergovernmental Programs Office. 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. The thinking was, “Can we do something disruptive in a way that we could really bring a value add to what we have today in the economic manufacturing present of our country?”.

This research validates the viability of a recycling and reusing process for end-of-life glass fiber reinforced wind turbine blades. Selecting each plane add a sketch. The only way i could print the blades was with surface mode. 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. It’s opening up what’s possible out there. So what we need to be able to do is say, “Hey, can we take the printer, put it out where you need the part and potentially be able to build onsite?”, So we challenged some of our scientists saying, “Why can’t we take what would be a 3-D printer to build a part that’s, you know, the size of my glasses, and build a printer that can cost effectively and in a timely fashion, build something that’s half the size of a football field?”. Did you make this project? Enjoy !!!! we had a module on 3d desingn (solidworks) and for one of the assignments we designed a scaled down turbine blade , printed it and tested it in the college wind tunnel recording rpm. Thingiverse is a universe of things. 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.
