Stool CNC

The project starts from the idea of wanting to redesign the Solvay stool from a redesign both for the digital manufacturing part and the material.

So, we wanted to transform different aspects of the original, based on different characteristics of it.

We also want to reform the concept and the potential that digital manufacturing brings us and of downloading an object from a bank of free files. This makes it possible to create a community among users, since it is a reproducible and explicit object, therefore, it could be expanded, modified, edited, transformed...

Materials:

• Calabó wood
• PLA
• Screw
• washers
• sandpaper
• bitumen
• Varnish

Machines:

• CNC
• 3D
• Manual milling machine

To start the project, we learned how to use all the necessary machinery to carry out our project. Then we started with the 3d machine, doing training and finally we modeled the drawings with autocad. Then we went to cut the wood with the CNC, gluing it with screws so that the iron was held in place. And they 3d printed the parts with PLA.

After many years of experience, we already knew how to use autocad for studies at the University, we used the typical tools such as the line or the circle. Always following the measurements we were given of the original stool. Once drawn, he joined all the lines to create a single vector.

Then I modeled the squares in Autocar 3d, trying to follow the aesthetics of the original. We placed it in the most optimal way when printing it.

After modeling the squares in Autocad 3d, I exported it to the router. I used 18mm wood. And we made 19mm outside cuts to make sure it would cut, with square top cutting bits with 2 1/4 flutes

After modeling the squares in Autocad 3d, I exported it in stl. I used beige PLA. We passed it to the Prusa Slicer program to set all the params

Once we have all the parts cut on the CNC, we will move on to milling all the corners. With a cutter with a diameter of 28.6 and a radius of 9.5.

Already milled, we will tint the wood to give it more darkness. (this is up to each person) We will do it with bitumen and a cloth. We will stain the cloth a little and spread it all over the wood so that it is homogeneous

And finally, when the bitumen has dried, we will varnish it with a colorless matte varnish. With the same bitumen system, with a cloth and spread it.

To mark the holes, we will place the square beforehand where the inner spikes and place them centered on the inner spikes
