In week 8 I finished my 3D model which I made from laser cutting.
Laser cutting is a non-contact process which utilizes a laser to cut materials, resulting in high quality, dimensionally accurate cuts. The process works by directing the laser beam through a nozzle to the workpiece. A combination of heat and pressure creates the cutting action (AMADA WELD TECH, 2023)

The first step was to use AutoCAD which is a software for 2D and 3D designs. I created the shape of the shapes needed based on what I did for the prototype. I started by creating the triangles which were 20cm x 10cm for the triangles on the front and 23cm x 10cm for the 3rd paragraph
For the facade I divided the triangle in multiple part of each 1 cm with a 0.5 cm gap in between each of them
Then for the roof and doors I used rectangle shapes. I drew rectangles of length 25.5 cm and width 4 cm
After I had all my shapes in, I went to the 3D printing workshop to use the laser cutting machine. I connected my AutoCAD document to the computer linked to the machine and started the process which took approximatively 20 minutes. The material used was Pulp wood 3mm
After cutting all my parts, the next steps was assembling them. To do that I used adhesive glue because it dries quickly and gives a clean finish look if used correctly
I started by gluing the third triangles parts together because it was the easiest part, after that I added the roof of the first triangle
After completing the 3rd and 2nd triangle, I had to work on the first one but I faced challenges as the measurements of the pieces were not correct. I had to restarted the processes from AutoCAD and calculate again my measures. I restarted twice because all the two times my measurement were not correct and did not fit. On the third attempt I decided to do it with my own hands and to measure directly with a ruler and this worked better than the laser cutting. I used a cutting board and a craft knife to cut the pieces of the facade
Once I was sure of the measurement of my pieces, I used adhesive glue to attach the small rectangles to the rest of the model. Gluing the larger rectangles at the beginning of the triangle was easy but it got tricky at the end and I used a tweezer to handle the small parts
Then I added grass on the biggest part of the roof. I used a craft knife to cut the grass into the form of the roof and used adhesive glue to glue it
To complete the model, I added the door and the window to the second triangle which I cut using the laser cutting machine and the material was clear acrylic
