# How to create sheets with filament spools

## Steps
### Step 1: Shredding coils
First, sort the coils by material type, such as PP and PS, and use an industrial shredder to create particles with a uniform texture of about 0.2 inches (5 mm).
### Step 2: Mounting the plate
### Assembly Instructions for Mould
To assemble the mould, begin by placing a thin metal sheet coated with natural wax within it. Next, position the structure according to the desired shape and size. For this example, the mould measures 60 x 60 cm (24 x 24 inches) and is 2 cm (0.8 inches) thick. The material usage for this mould is approximately 8 kg (17.6 lbs).
### Step 3: Heating the plate
Place the material inside and cover it with another sheet of waxed metal to prevent sticking. Activate the press and heat to 230°C (446°F) for 45 minutes or until the plastic begins to overflow. Allow it to cool after the heating period.
