Project description

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.

General printing recommendations

Printer size 25 cm x 25 cm x 25 cm (e. g. Bambu Lab X1C)
Enclosure Not necessary
Slicer Bambu Studio (latest version)
Filaments used LW-PLA (e. g. colorFabb), PLA, PA-CF low-warp Nylon (e. g. colorFabb)
Filament diameter 1,75 mm
Nozzle diameter 0,40 mm

Special printing recommendations for all LW-PLA components

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 Bambu Lab X1C and Bambu Studio as slicers are listed here.

You can start with that for now.
