Foldable Robot-B

$ 4.79



This is the 4th in a series of folding robots to prepare for 4D printing. This robot was inspired by robots in the TV series Lost In Space.
It is a typical form of classic SF robot design with Robby appearing on the forbidden planet.

This is the kind of "3D Fan art". My imagination has been added so it is difficult to see the original shape before folding it.

Designed for easy folding of complex structures, this product has been designed to meet the needs of popular 4D printing in the future.
It will revolutionize 3D printing as a totally new structure robot that does not need to be supported nor assembled, just fold.
This design does not require assembly, but the head, arms, waist, wheels etc, can rotate at various angles, so you can play with a variety of things.
Especially, the arm has a double structure so that it can rotate in two directions, so you can take many poses.
The folded part is made concave so that anyone can fold it easily.

This robot has a Caterpillar that is similar to a tank instead of a leg, but it has wheels so that it can roll.

The biggest feature of this design is a new composite structure with different areas of the fold. This was the first new 3D printing structure in the world, and it was particularly difficult to design the new composite structure so that the lower body and upper body could rotate additionally.

The order of folding this robot is as follows.

1. Lift the pins in the lower body.
2. Fold the middle part of the body except the head and lower body.
3. Assemble the lower body to fit the middle pin.
4. Fold the hook on the bottom of the lower body.
5. Press the wheels to fit together.
6. Fold the head and put it on the middle body.

For more information, please refer to the following YouTube videos.

Folding Process
Print using Prusa i3mk3

This new type of composite structure, which allows complex movements in a single print, will show another possibility of 3D printing.

You should never use support. If there is support in the gap of the movable part, it becomes impossible to move. It is recommended that you 'DO NOT USE Brim' but USE Raft for printing stability. The transparent part of the head can be printed out separately and then attach with glue.

This data may stick to moving parts depending on the status of the printer, so please check the status of the printer carefully.

    Just wanted to say that I think this is one of my favorite prints yet! I used your recommended settings and first print was amazing. I used eSun PLA+ filament and could not be happier with the results: it does not seem fragile at all. Next, since I do not have an SLA printer, I am attempting the globe using T-glase clear filament with a clear epoxy coat. I'll let you know the results.

    Thank you for sharing your experience and information about our design. Please continue to be interested in our design in the future. If you have any questions about 3D printing, please feel free to ask.

    Well, i did this Robot on my Ender 3 Pro done with Cura 4.0. Resolution 0.15mm. After 11 from 16 hours the Printer paused. 2hours later i resumed the Print. At the End of the Work, printing the Head, i noticed that the neck was losen. It rotates during the print. So the Face wont print right. What can i do that the neck keeps fixed. Any hint?

    In your case, the problem is that the head is falling off the plastic plate during printing. Apply some liquid - for example Magigoo, stick glue, hair gel etc..., or Use Raft so that the printout can stick to the plate. Thank you~

    Hi , it's amazing ... I bought a couple of models a few minutes ago , but in this case I didn't see the printer configuration like you show in the Piggy Bank. thanks

    We put slice settings on information(above explanation) Happy 3D printing! Thank you!

    Where does the clear part on top come from?

    2018-09-28 13:28:43

    It is included in the STL file you downloaded. The transparent parts of this photo are printed to an SLA 3D printer, not an FDM 3D printer.

    To the designer of these Robots. I am wondering if you would consider selling these as a full set at a set price and if so, how would this be possible? Thanks

    2018-08-24 13:53:29

    As a result of our meeting, we decided to give you an additional one if you purchased 8 robots. If a customer buys 8 robots and sends us an email, they will be able to download additional from their account. Thank you.

    Do you have any plans to bundle all your robots into one package?

    2018-08-01 12:23:14

    Thank you for your good opinion. Because we will continue to make robots, we are determined to be difficult to make package, so we are preparing a point method. Please look forward to!

    It would be better if the glass just fit in a slot like the Robot-R, rather than having to be glued on. However, I'm sure you would have done that, if possible.

    2018-06-15 18:41:49

    Thank you for your good feedback. I designed it to fit the glass part as you said, but it was not because of the original robot design. Next time I am editing, I will try to reflect your opinion.

    Love this one, great model! I'd recommend carefully watching the video before assembly, and note a reasonable amount of pressure required to 'click' the legs together first. Otherwise you may end up finding out that yes, PLA isn't that strong on the torso hinges.

    2018-06-01 11:49:18

    Thank you for your note! Your writing will be good for those who want to print this design in 3D. We need to consider the ability to upload videos to our service.
