Vacuum Forming List:
- PVC Plastic
- Objects with interesting shapes (note that this must be able to withstand high temperatures if not they will warp when boiling)
Instruction for Vacuum Forming:
Step 1: Turn on the machine and it heat up.
Step 2: We need an object that will not warp when heated. Place that object on the machine stage like so:
Step 3: lower the object into the machine and cut a sheet of PVC to fit over the mouth of the machine.
Step 4: Secure the PVC in place and then pull the heater over the PVC. When the PVC is sufficiently heated it will become smooth.
Step 5: When the plastic is heated, push the heating component back into place, and lift the stage with the object into the the PVC.
Step 6: Quickly turn on the vacuum function so that the PVC will adhere to the object shape. When the shape is to your liking, stop the vacuuming and remove everything.
I left the plastic to cool a bit too long, hence when vacuuming the edge was less defined then it could be.
We want objects that whose head is not wider then the base so that it can be removed later. If not the plastic would vacuum form and seal the object inside of it.
Thermochromic Printing Material List:
- Thermochromic pigment
- Paper Templates (optional)
- Fabric paint of any colour
Instruction for Boiling thermoplastics:
Step 1: Prepare silkscreen patterns, or paper templates for printing.
Step 2: Prepare Cloth for print
Step 3: Mix Thermochromic powder and the Fabric paint for silkscreen. We used 2 spoons of paint and 1 spoon of powder. In this case we used the clear paint so the colours disappear when heated.
Step 4: Lay template and/or silkscreen over the cloth and proceed to print.
Step 5: Leave designs to dry.
The coloured pigment came out dull on every other fabric that is not white. Even on white fabric they showed up faintly. If we want a darker line art there is always black I guess.
