I made the several models of "Fan" used for the turbofan engine as follows; https://www.thingiverse.com/thing:2926325 https://www.thingiverse.com/thing:3571806 https://www.thingiverse.com/thing:3573484 In recent years, a new concept fan has started to be used in medium-sized engines (with 50-inch class fan). This fan is called "Blisk Fan". Blisk refers to the rotor that combines blades and disk. Blades are manufactured by machining. Blisks have long been used in small and large engines for compressors with short blades, which do not need to be replaced on site. This fan appears to have been born out of a new concept prioritizing reducing the number of parts, weight reduction, and efficiency improvement over maintainability. I made this comparison to highlight these features. A. Parts of this model: ① Fan, Blisk type - Made commonly from titanium. B. Download files include: - Files: STL Files= 2 items STL file name: "ws" of last two digits means "With Support", which is specially designed. C: Purchase parts information; - Screws, M2x8 - used as a tool D. Assembly points - No special skill required. E. Total net print time: Approximately 7 hours - Estimated for PLA, 0.4mm nozzle, 0.2mm layer height, 40% infill and no raft or support. Note: When printing in actuality, each parameter may be adjusted by your experience. F. 3D printing settings - Raft, Layer Height, Infill: Depending on your experience. - My models were printed using "idbox" with a 0.4 nozzle and 1.75 PLA. I do hope you enjoy making!!
