http://ift.tt/2jQmT8S I decided to make a one foot diameter turbine duct for some experiments with thrust tests. This was quite the printing job so I thought I’d share the results. It took about 300 hours for the print to finish on the Z18 printer. The GE90 fan blade setup was printed seperately so that I could attach the turbine duct on my bike:https://www.youtube.com/watch?v=zgDTBiexoF0In hindsight I wish I had made the duct bulge outwards more like the 737 duct (it’s more efficient). If anyone’s curious to try the print I attached the 3d print files in the video description. http://ift.tt/2iiTQL8
