Introduction: 3D Print Skeleton Robot

About: Happy life lies in a peaceful mind. I like DIY everything, design special things, painting.

Skeleton robot is a very simple toy. Maybe you have already bought one, but do you want to customize a suit of it by yourself? You can add some icon only for you, or design your favorite charactors. It will be awesome!! 3D Printing will help you to make it real.

So, let's start!!

Step 1: Choose Software&3D Printer

Modeling Software: 123D Design Desktop

Get from here:

3D Printer: Up! Plus 2

Filament: ABS

Step 2: Design and Test Joints

This step was very important for this project. You must try to print out all the types of joints with different clearance, to find out the best combination. Different 3D printer with different filament, the clearance will be very different case. ABS was better than PLA to print joint structures, especially for ball joint.

Here is my research on different 3D printer and filament for your reference:

Printer+Filament | Clearance


Makerbot + PLA | 0.4mm, hard to separate them

Up!Plus 2 + ABS | 0.1mm, a little hard to separate them

Up!Plus 2 + PLA | 0.2mm, hard to separate them

So, you need to design the joint and print out, feel the joint, tight or loose was not the best. Then, modify your design and print out. Repeat this workflow several time, I think you must can find out the right one.

Once successfully, it will be easy for you to move to the next step.

Step 3: Create Model

After completing the previous step, create model will be easier. Just copy and paste the joint, then connect them together. Add head, hands and feet, it is easy. Export to STL, you can start printing it.

Here is my model, you can reference:

Step 4: Printing Out

2 hours later, it can finish printing. Remove the raft and support material, then break all joints gently.

Congratulations!! The skeleton robot appear, it can pose for your photos.

Step 5: Pose for Photos

Cool!! Start take photos for them with different poses.
