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.

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 one real tip, print this model slowly with a filament that sticks easily to the print bed. I had to manually issue gcode (M220 S30) to slow the printer down after the left inner wheel came loose from the print bed. Had I known this would happen, I would have enabled a raft and added custom code to change print speed earlier.
I just printed out this model, and everything came out perfectly except the top of the head. The problem happened because the head started rotating in place while it was printing, creating a weird afro. It seemed to be rotating from inside the model, so I'm not sure what went wrong. Is it supposed to rotate after you're done assembling it? Is there some sort of temporary latch of some sort that was supposed to prevent it from rotating until you assemble it?
I used all the settings you suggested except perhaps the overlap setting. Mine was at 25% instead of the 30% you suggested. Do you think that might be the problem?
I printed it out a second time using some glue to get extra adhesion, but I had the same problem. Another robot with wild hair. So, I printing out the head by itself (using mesh mixer to remove rest of model) and then glued it on to the first robot I printed. Yes, I had to cut off his head to do it.
I had another weird problem. Both robots had one bad wheel, and it was the same wheel. I even printed an extra leg out by itself, and that one had the same bad wheel. It's probably coincidence, but three identical defects does seem a bit weird. I even printed them on different areas of the bed to make sure it wasn't a particular area that had bad adhesion..
I am exited that I found this robot. I just purchased it but wonder if I could use cura slicer and what are the settings that work with it (or PETG and also PLA) . I have twotrees Saphire S printer and o.4 mm nozzel.
thanks.
Thank you for purchasing this design.
I test with various PLA, not PETG.
Please read the reviews and comments of other users carefully, and we hope that you will have good printing results.
And if you have problems, please check print-tips.

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~
I guess I had the same problem he did. How will glue solve this problem? The rest of the head seemed firmly attached to bed. It was only the very top part that was rotating. Are you saying that there's a hidden axle that runs all the way to the bed that is getting loose, while the rest of the head is not loose?
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?
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
good
