How to create sheets with filament spools

PS
PP

3D printing does not inherently generate waste; however, the spools used often become discarded by-products. After accumulating these spools for years, we have effectively repurposed them. Each sheet transforms 34 spools, rendering them suitable for diverse applications such as furniture and product design.

  1. 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).

  2. 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).

  3. 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.

3D printing waste reduction through spool repurposing involves industrial tools and custom fabrication processes. Below are the key components required for transforming plastic spools into sheets for design applications.

Tools

  • Material sorting system (for PP, PS, and other plastics)
  • Precision measurement tools (for 5 mm particle uniformity checks)
  • Thermal control devices (for monitoring 230°C/446°F temperatures)
  • Wax application equipment (for metal sheet coating)
  • Cooling timers (for post-press hardening)

Hardware

Consumables

  • 8 kg plastic spool material per sheet
  • Natural wax release agent
  • Heat-resistant mold seals
  • Protective gloves (for 230°C operations)
  • Insulation materials (thermal process safety)

All listed equipment can be sourced from industrial suppliers in Madrid like ~~Hercort~~ for shredders or ~~Tecni-Molde~~ for custom molds.
