RE: Fully 3D Printed DIY electric car
I managed to design a glue for PLA plastic that actually creates stronger bondings than epoxy ones.
More than a glue is a chemical welding product. It is made with a solvent (Dichloromethane) PLA as filler.
It really works well in PLA, PLA+ and PETG but need some more test in this last one. And it works perfectly for big parts like this project needs.
I am now working in the proportions (Filler/Solvent) in order to get the best results and easy to use. I will make a short of a manual of how to make it when finished.
Hope this helps to others.

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

Used filament is PLA or PETG?

Hi @clemens-m
I am using PLA PLUS from Sunlu, reasonable priced and tough as nail.
But not sure if I have selected a nice color for the door...
BTW, I am putting together a Hackaday project with info and updates here: https://hackaday.io/project/177105-jellybean3d-printed-car
RE: Fully 3D Printed DIY electric car
I am sure you will need a second loop - so I think colour is not important for the moment and there is still the possibility of painting. Do you think that heat resistance of PLA is enough?

RE: Fully 3D Printed DIY electric car
Yes, the painting option is always there...
Certainly PLA low heat resistance is something to take into consideration.
That is why I decided to use PLA+ that is has around 5ºC to 10ºC higher resistance, I think that with that will be enough for most of the time.
But I live in a very hot area (South of Spain) and I plan to use this vehicle for just short commuting (5-15Km, occasionally 40Km), most of its time it will live in a garage, but when outside I have to be careful not to park it in areas where it can overheat due to IR reflections or concentration.
The parts that are close to the motor and brakes are going to be made in PA.

Hallo,
have you done a rough estimation of weight of your vehicle. And do you need a certification of it to be allowed to drive on official roads? Still very interesting project! Have you done a bit of how much time you invested to design it. It must be lots of hundred hours?

RE: Fully 3D Printed DIY electric car
have you done a rough estimation of weight of your vehicle.
- Estimated Vehicle weight 75 to 85Kg (Final weight may vary depending on printing material/s, printing adjustment and components chosen)
- Cargo capacity: Driver + cargo = 130Kg maximum (estimation)
- Weight estimation for 3D printed parts is around 35 to 45Kg (It will vary depending on the material/s chosen and printing adjustments)
And do you need a certification of it to be allowed to drive on official roads?
I live in the EU so yes, you need a certification/homologation for everything, even just for waking up in the mornings...
I do not have the money or resources to do a fully certification. So I will sneak it into the e-bike type.
Have you done a bit of how much time you invested to design it. It must be lots of hundred hours?
With big projects like this, it is counted in thousands of hours, and I am still around half way... 🙄
Anyway it is a hobby project so I am enjoying it.

Have you read through this?
Also available in English - maybe some interesting additional information?

Thank you Clemens, I read it. Their results mach my research. But most of the tips there are for figurines and display object but not for functional parts, except for the CA different bondings.
And I think that instead of the Pattex "1 for all" they should recommend the Pattex PL600 or its equivalent Sikaflex -11FC+ that are better suited for plastics materials.

Hallo, long time no new information on your project. What's going on. How is progress on your "glue" and where can I get information about it?

RE: Fully 3D Printed DIY electric car
I started a new job some weeks ago so the project will continue but at a slower pase... but it is continuing.
@clemens-m About the bonding system; I have prepared all materials for the testings of different concentrations and will do the testings next weekend and will post conclusions and video about it.
RE: Fully 3D Printed DIY electric car
Hallo Gonper, congratulations on your new job, thanks for your update. I am very interested in your bonding system as it could be a solution for building wings of printed segments for a wind turbine.

RE: Fully 3D Printed DIY electric car
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 remarkably well.
If you are interested here is a video about it, make sure to see the end of the video...
RE:
I just managed to finish last video about this 3D printed electric vehicle 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.
