3DLabPrint from Czech Republic opened a webshop for 3D printable RC model airplanes. It is a nice little niche business. We will probably see more specialized model shops in the future.
Harcoreta made this incredible 3d printed jet engine for RC applications modeled on GE GEnx-1B. It is very detailed Electric Ducted Fan (EDF) motor with NTM 1400kv 35mm brushless motor located inside the core which is cooled by a small impeller. It even features working thrust reversal system. It was printed on Reprap Prusa I3 at 0.1mm layer height and then smoothed by using an acrylic thinner.
The files of it are not available ... yet
Details of thrust reversal mechanism:
Technical specifications of the model motor:
100mm diameter 18 blade main fan scale looking. 24 outlet guide vanes.
34 mm diamenter 18 blade internal turbine, installed on the back shaft of the motor, It's designed only for cooling the motor. Over this section there are a sequence of stator vanes and supports to optimize the airflow. This internal airflow could produce thrust but in any case it'll be a few grams.
Scale looking nacelle, the major differences are the simplified engine pylon and the minor reduction on the exhaust area, about 95% fsa
Thrust reverser, complete system with translating cowl, blocker doors and cascades. The most complicated parts that must work.
NTM 1400kv 35mm motor. Thrust target > 0.5Kg with 3S or 4S maximum.
Many thousands of birds die every year in collision with airplanes and they cause some one billion US dollars of damage. You don't want a stupid seagull flying in a jet engine during takeoff or landing, it will ruin your day. Some airfields have teams of living falcons chasing the birds away, but now there is a much more effective solution with some help of 3d printing.
These 3d printed flying predators are developed by Dutch company "Clear Flight Solutions" and come in two models: Peregrine Falcon and bigger Bold Eagle. They are made from foam material in the wings and bodies made of 3D printed nylon stretched over glass fiber composites. They fly powered with small electric motor which moves the wings and can reach speeds up to 80 kilometers an hour.
Beside airports they can also protect crops and garbage sites by scaring living feathered vermin.
