The Slow Bending Actuator is a basic Pneunet design that is based on the Slow Pneunet architecture. It is based on a research by Harvard University and the molds on this wiki are designed by Jonas Jørgensen - Researcher at the IT University of Copenhagen.

The fabrication process is based on the slow pneunet design and is similar to the one of the triangle mold and the gripper mold.

Here are the mold files for the actuator:

The bottom half of the top layer cannot be laser cut.

• Top layer: ~35g
• Base Layer: ~5g

• Dragon Skin 30: ~35min
• Ecoflex 30: ~15min

From the toolkit website:

Using a thin metal rod, pierce the end of the actuator, an equal distance from both sides
and about 1/8” (3mm) from the bottom.  Aim the rod slightly downwards and don’t push it in too far.
The goal is to reach the central channel without puncturing any of the actuator’s walls.
