Week 3 Computer-controlled cutting
Laser cutter test parts:
​
My design for the week of computer controlled cutting is base in a jigsaw exercise to learn about the molecules to create the green house gases.
​
I have modeled 2 different shapes to be connected between them in many possible ways. The user can choose how to create a 3D shape or molecule according with their wishes.
​
The pieces where modeled with the 3D software Sketchup to try different software for the same approach.
​
Also I have design the sing to guide the user in the elements involve to create the green house gases. The design was created with Inkscape and once I have the cutting and engraving I had use a line blender to make it “self- stand” and create the feet.
​
To create this assignment I have use the Laser cutter.
I have made my design to cut and engrave the pieces and the sing. My material is 3mm Acrylic.
​
The link of this exercise to my final project in aquaponics is the use I would like to approach in FabLab Cuenca explaining basic knowledge.
​
As the aquaponics evolve I would like to produce teaching materials or games related to the project, in order to involve the users of the space to learn and to understand the bases of aquaponics.

Assignment:
1-Group assignment: make lasercutter test part(s), varying cutting settings and slot dimensions.
2-Individual assignment: cut something on the vinylcutter.
3-Design, make, and document a parametric press-fit construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways.
Vinyl cutter:
​
I have created a design base on the famous iconic image "J. Howard Miller's "We Can Do It!" poster from 1943".Just changing slightly the shape and text
​
I had decided to cut it into 3 overlapping layers with the 3 different colors to create a vinyl sing for my computer.
Parametric design:
​
To create my model within a parametric design I have use the software FreeCad, as recommended in the Fab Academy lessons.
I had reproduced the two shapes of my design and I have constrained the lines to make them equal and parametric. Then I have them export in the file format extension .DXF to be able to process them and cut them with the Laser.
