Jellybean3D Printed Car

I just managed to finish another video about my FULLY 3D PRINTED #electricvehicle project. And finally I was able to test my ideas on a real part.
Looks like it holds quite well, I am very happy and proud.
It is just a 2 min. video. Hope you enjoy it.

After a long stop in this project, I was able some weeks ago to retake it.
I finished the development of the chemical welding for the 3D printed parts. And it certainly works quite well.
If you are interested here is a video about it, make sure to see the end of the video...

Here are some details about how the Jellybean3D is designed:

• The intention was to use 3D printed components and parts as much as possible, so I decided to make an unibody vehicle in order to avoid the use of a metallic chassis to support the body.
• Although a vehicle like this could be made by many other different approaches, it is designed to be 3D printed.
• Given the strength limitations of the materials available for hobby printers I have been very cautious on the structural design. So I created 4 different levels of structures: eggy shape, internal ribs (like airplanes fuselages), reticular structural web created by the bondings, and internal mesoscale structure created by the infill in every part.
• The big parts, body and door were designed as whole parts and later strategically cut in order to:
  1. Get the most strength in the directions that are more needed and make them coincident with the XY printing plane.
  2. Avoiding or enforcing the cuts in determinate areas in order to strengthen or not weaken them.
  3. Taking in account the appropriate cut orientations and cut locations in order to avoid the use of supports when printing.
• Some parts like the knuckles and others, have been topology optimised.
• For the non printed parts and components I tried to use very easy to find materials or components.
• In order to make strong bondings between the parts I developed a chemical welding system, more info here: https://youtu.be/5LqmyYqS6-k 

First parts just come out of the printer (door parts+), all looks good so far.
Next step  post-processing and chemical welding.

1/10 scale model of the Jellybean3D.

I have created a 1/10 scale printable version. The printing files can be downloaded from here: https://www.prusaprinters.org/prints/47678 or here: https://www.thingiverse.com/thing:4669754 

And assembly guide for this scale model is here: https://youtu.be/9_9_ydc-NO4
