Rolls Royce Trent 900 is a three spool jet engine that powers largest passenger aircraft in the world, Airbus A380.
I designed this based on the superb CAD model from Chris Shakal. The model is re-designed in a way, that only one part requires support. Most of the parts is printed with 0,15mm layer thickness, but you can chose your own. I chose this layer thickness, as it is very good compromise between speed and details. The walls are also optimised for 0,4mm nozzle (Auto/0,48mm extrusion width in Simplify3d) so there is no too thin walls that would not be printed.
The most important detail of this engine is that it is powered by electric motor and spools are connected with planetary gears. Although because it seemed more interesting to me, the spools do not rotate in realistic order.
I hope you will enjoy the printing as much as I did.
UPDATE initial
At the moment the installed motor is 12V/500RPM, but it is too weak. On order is 12V/100RPM. The slower motor has slightly bigger length of the gearbox, so there is a possibility that motor mount will have to be increased. I will post an update when I receive the new motor.
