ASSIGNMENT
Final Project
Group Assignments:
Individual assignment:
This week's group assignment can be found here.
Getting started with this week's assignment, following tasks had to be done :
VINYL CUTTING
At Cept we decided to print on T-shirts for this week. We designed the print and cut it using a Roland CAMM-1 servo. I designed my graphics using Illustrator and exported the file to eps format.
Next step was to load the Paper on Roland CAMM-1 servo. The machine checks the roll and gives us the dimensions of the paper.
I followed the following steps to start the cutting. Please see the image on right for reference.
Next I started the cutting and once it was cut, I used it as a template and used colour to print my graphics on the tshirt.
LASER CUTTING
Well I stated the assignment by understanding parametric Design.
When we Design for laser cutting we need to know the exact value for Kerf.
Kerf is the distance between two edges of your cut.
In Other Words,Laser Burns the material with the width of Kerf
To determine this, I made grooves with different widths.
I observed the following things:
Having done this test, I decided to start my Parametric design. Well What I understood by the term parametric design is that we are making our 3D Model such that the Values we use for modeling should be easily editable. Instead of fixing a length or width, we can use value from parameters we have defined earlier To enter parameters or say global variables that can be used through out your design.
I used Grasshopper plugin for Rhino to design my geometry.
I added following parameters to my design:
Once my polygons were ready, it was time to start preparing for Laser cutting. Our lab had Epilog Mini.
I followed the following steps:
Next select "Piece size" to 24*12 inches which is the bed size of our laser cutting machine.
And then click on "Colour Mapping" for other settings
Here are my cutting samples and assembly photos
I have attached following Files
1) Grasshopper Parametric Design File
2) Cutting File in DXF format
