Wall-E Foldable (Print-in-place Articulated)




Since Fab365 designed the Foldable Robot, there have been many requests to design the Wall-E in a foldable way. This is because Wall-E is optimized for foldable design. However, the shape optimized for foldable is only the body, and Wall-E's head/eyes, arms, wheels and track are a challenging shape with many factors to consider.
Now that we too have gained a lot of experience, we now have the skills to create, and finally we can design like this.
Please enjoy the foldable design skills that Fab365 has accumulated over the past 3 years with the Foldable Wall-E.
Here are some things to keep in mind when making Foldable Wall-E.

When folding the body, make sure to check the positions of the protrusions and holes before folding.
The parts attached to the upper corner of the Wall-E's body have a small adhesive area, so it is recommended to apply the adhesive carefully before sticking.

The neck must first be pushed up and then rotated before it can move.

The arm moves along the rail. On the lower rail, it moves well when the arm is forward, and on the upper rail, it moves well along the rail when raised up.

To make the track move well, it's a good idea to grease the wheels with sewing machine oil.
If the tracks are well separated, it is helpful to increase the flow rate.

    I have tried a couple of times to print this but have failed. The main part of the body has several small "dogbones" that hold the parts together. Unfortunately they will not stay stuck to the bed despite several attempts with bed adhesives. The problem is that they have very little surface area and while they are printing, the "ears" of the dogbone start to curl up. The printer nozzle passes over them and knocks the dogbones off the bed. Any suggestions?

    This is so cool!
    First, thank you so much for your hard work, and second for making it free for all to enjoy!!
    I have questions, can I print the tracks in TPU? Will it work if I do?
    Thanks again

    I have successfully printed everything on my Ender 3 Pro-0.4 nozzle, however the track keeps pulling apart when assembling. I am using ESun E PLA.

    is it normal that the left body part from the main body is not touching the plate? I have to put support on it!

    see the image, it is like that for 3mm, and then the part appears !

    2022-06-24 05:28:22

    Most likely the part isn't sitting flat on the build plate.

    2022-06-25 03:03:49

    I've reopened it multiple times, and everytime, just this part is about 3mm in the air. Like if it was moved just before saving the stl.
    I'm using prusa slicer 2.3.0

    Having this issue also. Noticed the first few mm of the model disappears so there is something wrong with the STL most likely. You can see the overhand issue when slicing the model

    2022-06-25 11:29:25

    Figured it out. I went through PrusaSlicer to repair the STL and now I can slice the complete body now

    2022-06-26 01:36:46

    Same problem. Prusa slicer doesn't like it. Just fix it with netfabb in prusa slicer.

    What nozzle size did you use please?
    It is a beautifully designed model. Thank you.

    Amazing design, is support needed to print all these? Thank you.

    What filling percentage do you recommend for all pieces?

    2022-06-22 15:26:25

    infill - 10% 😁

    Another great design, thank you.
    Having trouble identifying colours for each part.
    I will have to track down that particular yellow for body. I can see silver for head and white eye outline. Are hub caps silver or light grey? Are tracks and body edges dark grey?
    I hope you dont mind me suggesting something for future, can you include colour in the file name, would make it simpler?

    2022-06-22 15:28:58

    You have matched all the colors of the filaments. great!
    I will consider your idea~
    Thank you~

    How big is this finished and assembled on 100%? Can i scale it bigger?
    Sad eyes dont hold the angle
    And many things at once at the Body Part. Chassis + gear. Hope this will print good
    And will EVE come also?

    2022-06-22 15:31:48

    When this is completed, the height is about 160 cm in size.
    Since the head, arms, and fingers are floating in the air away from the body, I am thinking about how to make EVE.

    2022-06-26 01:33:10

    160 cm. Almost like me. ;) :D
