3D printed tricopter - from CAD to reality!



I'm Adrian from Hungary/Europe. Let me introduce my tricopter project.

My goal was to make something really good-looking copter that have ally features I need.The design process started 1 years ago. My first idea was to make a composite chasis, from glass/carbon fiber.I designed the copter in a 3D modelling software, and also designed the necessary moulds for making each parts, here is the initial design:


This is a sample of the mould design:

I also made some FEM calculations, to check the stress dispersion:

Unfortunatelly, this type of production would cost too much for me. I tried to find partners in Hungary, without success. So I almost forgot this project. But some months before I read a lot about 3D printing, and finally I found a great partner in Hungary (many thanks to the Ground Zero Team www.groundzero.hu !!!). So I started to redesign my copter according to the requirements of 3D printing:


Then I sent the .stl files for FDM printing. Here is the result:


This is my current configuration:

  • Turnigy SK3-2826-1130 motors
  • 8x4,5 karbon SF props
  • 10A HK ESC (simonK firmware)
  • ArduFlyer 2.5 with ArduCopter 3.0.1 code
  • 2000mA 3S lipo (2 db 1000mA 3S2P)
  • Flytron 25A ultralight current sensor
  • MKS-DS95 servo
  • RECOM 5V 1A power supply for electronics
  • 3DR 868 MHz telemetry module
  • RCTimer OLED screen
  • Immersion 600mW 5.8 video TX + Coverleaf antenna
  • MinimOSD, with KVTeam code
  • KPC-E700PUB camera
  • FRSKY Futaba FASST-compatible receiver, PPM
  • controlled LED-s and buzzer

All-up weight is 782g, and has 8 minutes of safe flight time with 20-25% of remaining battery.

(Please note that I used Crius AIO Pro at first with MWI code and KV-OSD code. These can be found on the following pictures and in the videos.)


LED sripes are controlled by APM:


Here are some videos:

Flight test (with Multiwii)

Onboard video (with Multiwii + KV-OSD)

stl files can be downloaded from here:


And these are the additional metal parts for rear arm control:

I wish you all good luck on reproducing my tri.

Please note that I'll not modify desing according to personal wishes, since my spare time is quite limited and I focus on my personal projects. Thanks for understanding!!!


Best Regards

Even being registered, it is not possible to download the files ...

Andrian, only "Cover" has got icon of Download in the lower bottom else other parts does not show Download icon.

Comment by Adrián Nagy Hinst on September 9, 2013 at 8:35pm

Yes, my bad.

I had to allow download for each files one by one.

Now it should work.

you will need one of each, except 3 arms.

Holy cow ! I got the files and used Meshlab and it it FANTISTIC. I may try with the makebot 2 to try and make it.

BTW you guys do know mt avatar is my runways at my ranch in New Mexico don't ya.

Good luck on it!!!

Please post the results if acceptable.

ps.: Only the printing of center part took more than 20 hours for us... :S

I will put the machine outside on the balcony ! Check it every day or two.

@ 67 years old what else would  do ? Sit in a rocking chair !

Comment by Earl on September 9, 2013 at 10:01pm

This is a definite winner. You (or someone for you) should do a kickstarter project for this. I'm sure you could raise enough funds to be able to quit your day job!
