Basically, in this exercise, we make a pneumatic construction using the technique of surface interfacing by making a sandwich of two sheets of vinyl thermo-lapped, or thermo-polyurethane, and in the middle an insulating sheet that can be Teflon. However, a cheaper version and made for the projects DIY is the baking paper, this technique is used in the T-shirt printing method using the press for transfer. described in the following presentation:
Design the piece of pneumatic thinking about of the shape-changing motion that you want to achieve: In this case, you can consider in the following shapes presented in the following examples
The essential rules as that you have to connect all the chambers for the air/ fluid circulation
Preheat the heat press depending on the temperature of the vinyl, c.a.120° - 140° C.
You can use the vinyl cutter to cut delicate pieces that require more precision or natural nice looking.
After having the cut of these two feet in need to put the insulating foot between the middle.
Make sure that in the middle there is a thin piece of baking paper for the air tube inlet.
Put two sheets of baking paper or Teflon sheets at the base of the dam and the top.
Press the material for 15 seconds. and wait for it to cool down.
Remove the pieces of protective material gently for the vinyl pieces making sure not to break the vinyl.
Insert the tube in the Inflatable and isolate it using a shrink tube and a lighter or heat gun.
Proceed to inflate and have fun with your device
