This is the third in a series of folding robots to prepare for 4D printing. This robot was inspired by a tin toy robot. The robot that puts the battery in its legs and the smoke in the mouth was a toy I wanted to have when I was a kid. Although this robot can not walk or smoke by electric power, it is newly interpreted to be optimized for 3D printing.
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, and legs 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. In addition, the legs are made to protrude to the front and back, and the angle is precisely adjusted so that it does not fall over.
The folded part is made concave so that anyone can fold it easily.
The biggest feature of this design is the application of the new dual structure. First of all, we made the cover of the robot's legs open and closed. Secondly, the needle can move according to the movement of the switch on the chest.
This new dual structure, which allows complex movements in a single print, will show new possibilities for 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 and 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.
The order of folding this robot is as follows.

Hi. I have a problem with folding. Always when I fold it breaks. Any solutions? What filament should be used for not breaking during folding? Thanks!
Once purchased, what permissions or restrictions do I have to edit the file and display 3D printed robot variations?
The print comes out beautifully except for the leg covers. I may try a greater infill. Any other suggestions?
Infill is not an option in this case, as it is about how much of the output will fill inside. If the problem is that the cover of the legs is falling off, I think that the hinge part is less printed. Therefore, it will be better if you reduce retraction or increase material flow.
I hope you find this helpful.
I've printed two so far and I can't get the dial in the front to work without breaking the switch... :(
It is very sad that the printing was not done well. If the surface of the printing is uneven or there is a lot of thread, the gap between the parts may become narrower.
In this case, it is helpful to increase the value of retraction or slow down the printing speed.
Finally, if you increase the size of the printout, the gap between the parts will increase and you will be able to move well.
I hope you get good results.
If you could start providing infill information, that would be helpful. Thank you.... I really love your designs.
Thank you for your feedback. In fact, infill did not have much impact on quality and did not put it into the information. However, many people have been asking for infill information. I will be sure to include infill information in the future. Thank you.
