Basics
- A Robotic Arm which has most of its componets 3D Printed
- Reduces cost (ie no metal cutting needed), at the price of some small structual strength/enviromental hardening
- Great for prototyping, development, and indoor small-medium load use
Team Spain
- BCN3D - [1] - all open source.
Team Germany

Intro
- Skyentific
- A Youtube Channel, which has develpoed and tested a few iterations of this concept
- The Most Recent Design Uses:
- Not 100% completed, but the last few DOF/Axis are near complete (also some of this may be premade, but released slowly to satisfy the Youtube Content Treadmill
- Has 7DOF total
Notes
- Good one - RAMPS controlled. Need to program it via code.
- No feedback.
- Practical use case - if we can create software to generate toolpaths, this would be a practical welding robot when scaled up.
- Easy concept - 6 degrees of freedom, + 6 stepper drivers. Scalable - as drivers can be whatever size required.
- Great project for open source TB6600, open source Arduinos, 3D printing, 3d printed belts and bearings for larger size machines.

Scalability
- Mechanically, this can be scaled up to whatever size stepper motor is available. with proper geometry, allowed forces can be large.
- Basics: if we have a 50lb force with a 1/2" pulley and 15mm GT2 belt - we can get to 500 lb pull readily on a 5" pulley! Good forces are allowed. We can probably get 5 kg load on the end effector for an industrial welding robot.
