I chosen PLA because it is easy available and mainly because it is easy to print. As well because it is a very strong material and long outdoor lasting, and actual good quality PLA blends have enough temperature resistance. Anyway PETG can be an option if PLA fails.
@@gonzalop.chomon327 OK if you live in cold climate, but PLA can melt easily outside. Especially if you park it next to a reflective object, like a window or mirror by accident. It might be fine in the mornign, but when sun angle changes can become like a magnifying glass.
@@commonsense3652 I live in the south of Spain, a VERY hot area with lots of sun. And before I decided to go for PLA I did tests, no problem so far with good quality PLA. It is short of a myth that good PLA gets soft with just sunlight. Anyway the decision to use PLA may change to other material if it demonstrates not to be suitable for the task.
@@gonzalop.chomon327 that is not a myth. Ok, if you print I in white it might not be that succeptable, but object can get to 80+ deg C in the sun easily and PLA without annealing will NOT hold its shape even under its own weight, and annealing process warps the parts heavily unless you do tricks like burying them in salt during annealing.
@@Balorng Yes, standard PLA softens around 55ºC , good quality of new PLA blends get soft around 70ºC and for this experiment is more than enough even for the area I live in. Anyway as stated in the description if PLA proves not be able to handle the task I will change to PETG.
This is nice ! can you please show the process how you go about to design 1 large 3D object and cut it to 200 pieces I want to make something like this but no idea how.
To do the cutting is not an easy task as you have to take in account quite a lot of things, like printer size, printing orientation, position of the cuts, assembly process, etc. In a few days (maybe weeks) I will post link to the 3D design files so you will be able to see how I made it.
How long will that take to print with 200 parts? Wouldn’t it be better to have the parts mechanically lock together rather than relying on a butt joint with some bracing? I don’t see the point of relying on home scale 3D printers. Can’t you contract out to get larger sections printed?
Thank you for your comment Tim Bo Estimated round 400h of printing time. To have an interlocking system plus the glueing/welding will be great but I have not found a reliable way to do it in the CAD software. This is an experimental project that aims to explore the limits of hobby 3D printing, This project does not aim to reproduce a standard vehicle construction.
@@gonzalop.chomon327 Thank you for replying. It is amazing that such a thing is more than just a thought experiment. It indicates what is coming in the next 10 to 20 years. Good luck with the project. Maybe you can "crowd build" the parts?
@@tjejojyj Crowd build has been already suggested and it is a great idea, and it will be very cool if made from pieces sent from people from all over the world. But the project is already very experimental so adding more uncertainties (different materials, settings, tolerances...) to it I think will be too risky.
@@rafaelamvl I will upload all files, design and info files in a few days (weeks maybe). Still not finished but it will be posible to start work on it and start printing...
your biggest problem is plastic is heavy and not that strong. At a minimum you will want to have at least a few main aluminum tubes to carry the weight of person and support wheels.
Yes that is true, plastic is not the best material to build vehicles, but this is just and experimental vehicle that explores the limits of hobby 3D printers. There is some aluminium brackets and nylon 3D printed parts on critical points. But let's say that 99%+ of the unibody is 3D printed.
@@gonzalop.chomon327 I dont' think it will work well, but good luck. Aluminum is not that expensive and would make it practical instead of just experimental.
@@commonsense3652 Yes, there is many chances that something does not work in this project. But as said it is an experimental project. I already made aluminium, steel, composites chassis, and I know they work perfectly and they are the most reasonable way to make a vehicle. But who we will be if we do not experiment?
@@gonzalop.chomon327 You know about B&V-246 with Sorel concrete wings, it does not admite steel as reinforcement, but as concrete is a 'composite', tests of different materials in mix can be considered. Salut +
@@marshallrichardson3207 Very interesting. Actual shape of the Jellybean and structure is similar to that beetle body. If I find a good way to glue/weld the parts it will be almost the same. Because I plan to use gyroid (similar to puzzle jigsaw) internal infill structure that absorbs a lot of energy under deformation before failing and even more if structure fails.
@@gonzalop.chomon327 yes, when I saw the Jellybean, I immediately thought of the beetle for the shape, as well. And considering that you have multiple pieces to connect, the way that suture is would be very helpful. I’m excited to see how your project progresses! Good luck! If there is any way I can help further, please let me know.
Thank you seasonunite, that is a great idea, and it will be very cool if made from pieces sent from people from all over the world. But the project is already very experimental so adding more uncertainties to it I think will be too risky. But anyway really appreciate your offer and idea.
Great video will be interesting to see the finished product.

Cool idea! I wonder how long PLA would last though - I've had PLA prints warp in my hot car before :(

Anyway PETG can be an option if PLA fails.
good idea, but PLA distorts when it gets hot.
The idea is to use good quality new PLA blends that are able to hold heat better.

Is this meant to be available for hobbyist? Like a DIY project with home 3dPrinters?
Yes, you will be able to download all files to print and all information in order to make your own.

If you need a piece, I can 3d print one and send it out to you.
