A new attempt has been made on the basis of the folding crossing machine. Different materials and structures can be used for reference.
Common crossing machines are composed of carbon fiber plates. The design of Takiwa Zhihang uses 3D printing technology to increase the aesthetics of the crossing machine. At the same time, it also recognizes the influence of some crossing machine materials on flight.
The photosensitive resin material shell is relatively brittle and is easily affected by the light environment, which improves the appearance and also increases the take-off weight.
This design uses TPU flexible material, which slows down the impact during landing and is not as brittle as photosensitive resin.
The 3D folding structure design is adopted to easily realize the conversion between folding and unfolding.

Light curing shell design
Photosensitive resin 3D printing process is not recommended for use on high-speed unmanned aerial vehicles.
High light curing accuracy but material selection is also crucial
Photosensitive resin is brittle, easy to crack, and easy to change color due to environmental influence.

Shell-less fuselage design
TPU material was used for printing.
Compared with photosensitive resin, it has better toughness and can better protect the arm. The disadvantage is that it is not stable enough.
