Nostalgia meets technology in this printable model. The Do-31, developed in the 1960s, was based on two Pegasus engines, which were designed as cruise engines.
Two additional outer wing nacelles, each with 4 engines, made the Do-31 a functional Vertical Takeoff and Landing aircraft. Unfortunately, the project was discontinued in 1969 and we have now revived it.

Most components of the jets sold here are designed and optimized for a stable lightweight construction with LW-PLA. Since this foaming filament requires special parameters for successful printing, which vary from printer to printer and also from slicer to slicer, you should make your own printing tests in advance. You can find many tutorials and tips on the Internet and on YouTube.
The basic default settings we use with a Creality CR-10 Max, CR-10 V3, Ender3 V2 and Cura as slicers are listed here.
