Aero Mobius Drone Frame

Firstly, I am honored to have received an official invitation from Bambu Lab to design this very interesting concept aircraft

   "**Multi-engineering material fusion printing, assembly-free multi-material Print in Place forming, each material can play its own functional role**", my eyes lit up when I first heard this concept, which led to many interesting designs. Later, the topological configuration of the Möbius strip was chosen, which was perfectly timed and clicked instantly

   Three months ago, I happened to discuss the possibility of a Möbius strip design with several aircraft model designers, but many ideas remained hypothetical due to difficulties in forming them... Unexpectedly, during subsequent communication and exchanges with the Bambu Lab team, the integration of different ideas led to this very interesting Möbius strip topological shape. At first, I was worried that my ideas might be too wild and that the actual modeled shape might not meet expectations, but the subsequent design phase went very smoothly, and the continuously forming structures gradually exceeded expectations

After three simple versions of design optimization, this aircraft is finally presented to you

【Material Distribution】

· Main body (PA6-GF Black + PA6-GF Orange)

· Flexible material area (TPU FOR AMS Blue)

· White expansion area (PC, PETG)

· Support filament (PVA water-soluble support filament)

{Due to the method of mixing high-temperature and low-temperature materials for printing, improper setup or operation by beginners may cause damage to the machine. Currently, the preferred recommended configuration in this article is for uniform room-temperature filament. If you need the standard configuration for the sample model, please use the print profile published by the second official MakerWorld account. PETG material can be used conventionally}

Utilizing the characteristics of different 3D printing filaments, the entire aircraft is functionally partitioned (core stress zone, external anti-collision zone, bottom landing gear zone, internal shock-absorbing gimbal zone, battery fixing zone). This forms a complete, smooth overall shape, with different material functional design partitions to achieve different effects

The battery compartment adopts a combination of internal impact-resistant material + external flexible material, using a half-rail and half-magnetic method to easily achieve battery fixation and release. The main flight control area uses flexible material as a buffer structure (the inner and outer ring materials can be disassembled or retained according to the actual flight control board specifications)

【Printed Product】

   Some of the filaments used in this design are special high-temperature engineering materials. The integration of different materials creates difficulties in the actual printing process for this project, along with excessive filament change waste and greatly increased costs.

   Thanks to the new color-changing solution carried by H2C—the **Vortek** automatic hotend switching system—this design can be realized smoothly and efficiently in reality (when I received H2C and started print testing, I was amazed by the seamless hotend switching action of this system, it's so cool!!!)

Total takeoff weight = 226.6 grams

【Electronic Components Selection】

(The configuration I use is for reference only)

· Motor: Zhiying 1303 6000kv

· Propeller: 3018 two-blade propeller (1.5mm aperture)

· Flight controller AIO: Jin Hang F411aio (40A), XT30 plug

(Adapts to three specifications of flight controller board sizes, small aircraft have limited space, flight towers are not recommended)

· Lithium battery: Gens Ace 3s (11.1v) 450mah 75c, XT30 plug (There are two types of this battery model, this aircraft is compatible with the long strip version)

· Camera: RATEL 2nd Gen

· Analog video transmitter: vtx20 600w

· Battery compartment magnets x2: (specifications 20*10*2mm)

A remote controller and corresponding receiver are also needed, as well as analog video receiving equipment (FPV screen or goggles), to be selected according to demand

【Installation Layout】

Due to the special shape, the motor wires of the flight controller need to be soldered before the flight control board is installed

Happy creating! I look forward to seeing your Möbius aircraft!

See you in the next project!
