During the 3rd Term of the Master of Design for Emergent Futures in IAAC, we had a intensive week of project. So the main goal was to create an artefact that will help me for the exposition of our year project in Las Tres Ximeneis in Barcelona, in June 16th-19th 2025.
To put a bit of context, my broader project rethinks footwear beyond globalized, standardized design. And with espadrilles/espadrenyas, rooted in Catalonia and France, I want to represent sustainable, local craft, to make a parralel and a critical vision of the footwear industry. By reconstructing their making process, I propose an open, adaptable model.
This machine is one piece of a larger system of reclaiming forgotten know-how.Together, they question how we walk, and what traditions we carry with us.
The first part of my project was to find different references of braiding machines, and if it was possible a braiding machine especially made for espadrenyas in 3D ;) But unfortunately I found just normal machine to braid and just videos of some reall old braiding machines for espadrenyas with no informations on it.
So after a lot of times trying to understand how these machines works, and inspiring me with a basic braiding machine that a guy did and made a video of it, but asking for pay to have the 3D files of the different parts. I decided to make in a first this time the machine totally in 3D with Solidworks.
So after creating 60 pieces for the assembly on Solidworks, the final machines looked like this :
But how you can see, is missing some little parts because I didn't had the time to put all the little pieces on the assembly.
And after this I had to figured out how to make all of this.
The base and flat parts, I made them with laser cutting some acrylic (3mm thickness) and laser cut wood (4mm thickness). And you will see that the acrylic of 3mm thickness it's not maybe the best idea, it would be better if I used pieces of 5mm because it's more strong and it's not folding with the vibrations and the height, at least less...
After, all the other parts, like the gears and the supports are made with 3d printing. I had the luck to have the possibility to use times BambuLab printers, that mades wonderful final pieces. But also I used Zortrax printer. In the one week timing it was really hard to print all of the pieces, because these printers I had to shared it with all the students of our school, and the printers often encounters problems.
Also a lot of failures with the different tolerance of the printers and the differents components I bought. Like for example I bought some 10 mm tube and bearing with an internal hole of 10mm, so that was really complicate to put the tube inside the bearing, I had to sand it a lot. Furthermore some prints had some differents tolerance between each printer, so a lot of afterwork I had to do it on some parts.
Moreover I had to add a motor to make the gears turning, and because I didn't really knew the speed I needed to put, I decided to add a potentiometer with a mosfet to control the speed (particulary the voltage).
Unfortunately in this week, I didn't reach to finish it. The main problem is on the pieces that keep the threads, because the part that need to touch the gear to make them turn is to small and also the 3mm acrylic is to flexible. An other problem is that the big gear are on some laiton pieces really small, so the gears are not enough stable and they don't stay straight away. These things, I can make them work for sure but I think I need a bit of more time to do it.
