KUZUHA（Re:Filament Earrings ）

3D printing is an exciting and creative process, but it inevitably generates waste such as purge lines, failed prints, and leftover filament.

This project transforms those discarded materials into something meaningful — wearable earrings made from recycled filament scraps.

By heating and reshaping waste filament, unique color blends and patterns naturally emerge, resulting in one-of-a-kind accessories. No two pieces are ever the same.

This process is designed to be accessible and adaptable, allowing makers of different skill levels to experience turning waste into value.

⚠️ Safety Notice
Heating filament may produce fumes and high temperatures.
Always work in a well-ventilated area and wear heat-resistant gloves.
The creator is not responsible for any injuries or damages.

🧩 Materials

• Recycled PLA filament scraps (approx. 2.1g – 2.3g per piece)
• Silicone mold (heat-resistant up to at least 230°C / 446°F, e.g., baking molds)
• Forming mold (3D printed)
• Small hot plate (capable of reaching approx. 230°C / 446°F)
• Heat-resistant gloves
• Earring parts (flat pad type)
• Silicone spatula (heat-resistant up to 230°C / 446°F)
• Silicone spray
• Scraper
• Adhesive
• Handheld rotary tool (for finishing)

🔧 Process

1. Prepare the material
Select the desired colors of recycled PLA filament scraps.

🔧 Process

1. Prepare the material
Select the desired colors of recycled PLA filament scraps.

2. Soften the filament
Heat the hot plate to approx. 230°C / 446°F and place the filament scraps on it until they become soft and moldable.

3. Shape and press
Using a silicone spatula, transfer the softened filament into a mold pre-treated with silicone spray, then compress it into shape.

Note 1: Work quickly, as the material hardens over time.
Note 2: Apply firm pressure — ideally using both hands and enough force to fully compress the material.

4. Cool and finish
Allow the piece to cool, then remove it from the mold.
If it is difficult to release, use a scraper.
Trim excess material with nippers and refine the surface using a rotary tool if needed.

5. Assemble
Attach the earring parts using adhesive to complete the piece.

✨ Result
Lightweight, unique earrings created from 3D printing waste.

A small but meaningful effort to give discarded materials a second life.

💡 Notes
Variations in color and shape will occur depending on the material mix and quantity used.
These differences are part of the charm and individuality of each piece.
