We wanted to stick the tarpaulin with a glue gun. But this test was a failure:

We then did other tests: glue hot plates like a straightener or an iron. To do this we used parchment paper not to burn the tarpaulin directly, but to transmit the heat only. The test was very conclusive.

Following our observation of the Fabacademy, we wanted to try to stick the tarpaulin with the laser cut system. For this, different tests have been carried out, playing on the speed and the power (more or less strong), and perfecting it thanks to a herbarium system.

We chose to do our combination by sticking it thanks to the heat transfer system by straightener and iron. It was necessary to find out how much the laser cut the tarpaulin without burning it. It cuts at a speed of 100 - and a power 10. The size of the laser being only 120 by 80, we made the decision to separate the combination into two parts to be assembled. We then drew a first pattern. It was a little disproportionate, but it allowed us to see on a scale 1/1 how to assemble the patterns and the tightness of this combination.

It was of course possible to rectify this error and rework the boss. But thanks to it we could see where they were and improve the pattern that is now more realistic and more accurate. A second boss is added after the combination, the "sock" part.

We still wanted to know the price of these tarpaulins in India, so we did research on the different prices and we know that the price of a tarp like that of NGOs 70 grams cost 91 cents, for a thicker tarpaulin and more resistant the price is 1 euro 95 cents, which is affordable to have a more resistant combination with the same proceed.
Following a discussion with Kerala, we looked at another material that is natural latex. It is produced there, it is inexpensive (1 25 euros the Liter) and much more resistant than the tarpaulin. To create this latex combination, you have to have the negative mold, that is to say the shape of the body in full. The first step was to draw this body in 3D to be able to cut it to the CNC.

But we wondered what materials could be used to make this model. Knowing that the material used must be adapted to the machine but also that it is a good adhesion to latex and that it is easily removed even without the application of talc. We did two tests.
