An alternative to the heat press is the impulse sealer, which does not require an acrylic frame and is a fast way to produce prototypes. This method, however, is more susceptible to imperfections and requires the LJS to have a simple geometry.
Sealing with Impulse Sealer
Impulse SealingCover internal material (e.g. paper sheets) with TPE in the bottom and top layers. Seal every side of the Laminar Jamming Structure.
Adjust the time of application according to the type of TPE used. In this tutorial, we applied the sealer for 3 seconds using the Strechlon 200 TPE with 0.0015" thickness.
Do NOT include the tube inside the TPE container.
Carefully cut extra material outside the sealed area. |
Create a small cut to insert the plastic tube. |
Seal it with PTFE thread seal tape. |
Wrap the interface between the tube and the envelope thoroughly. You have now finished the fabrication process. |
