In this section, we will provide step-by-step instructions on how to fabricate Laminar Jamming Structures in a laboratory environment. Please refer to the Design section or the Design Tool for recommendations on design choices. We will additionally cover alternative methods of fabrication in the Classroom section, which illustrates accessible and fast methods of prototyping LJS.
The main goal in the fabrication of LJS is to obtain a component which is completely airtight - except for a small tube connection - and in which the enclosed material (here referred to as filling) is arranged in layers that are in contact with each other in all areas. The surface contact area between layers should be maximized, ensuring that the entire structure gets jammed .
An overview of the process is provided below:
- Set-up: Cut acrylic frame and filling material
- Step 1: Vacuum form TPE layer to the acrylic frame
- Step 2a: Heat press TPE case with filling
- Step 2b: Impulse seal TPE case with filling
- Step 3: Look for leaks and adjust tube connection
