Alternative to Heat Press/Impulse Sealer


The following materials are necessary for this tutorial:

Alternative Materials

Aluminum Foil                                                      TPE Sheet                                                       Small Iron

Heat Sealing with Iron

Alternative - step 1 Firstly, cut a piece of aluminum foil significantly bigger than the filling material.
Alternative - step 2 Mark the geometry of your filling material with a marker.
Alternative - step 3 Enclose the filling material between two sheets of TPE.
Alternative - step 4

Place the aluminum foil on top of the top layer of TPE and iron the sides of the filling material, being careful to not iron inside the outline.

Alternative - step 5

The temperature of the iron and the time needed to correctly seal the TPE will depend on the iron settings and the type of TPE used. To check if sealing was successful, gently try to separate both layers of TPE after ironing them. If the layers can still be detached, iron the region again for more 5-10 seconds.

Alternative - step 6 Continue ironing every side of the Laminar Jamming Structure. 
Alternative - step 8 After ironing the structure, a sealed strip should be visible in the TPE. Carefully cut extra material and follow the instructions at the Fabrication: Classroom - Impulse Seal and Final Adjustments to connect your tube and prevent leaks from your Laminar Jamming Structure.
