I aim to promote the reuse of 3D printer waste and prevent users from feeling discouraged by the waste generated by 3D printing. If you support this initiative, please consider BOOSTing to help fund our future activities.
First
This model is inspired by the following design: link.
I appreciate and respect the original creator's idea.
What is ReCharmed ?
This mold is designed to transform 3D printer purge material (Poop), purge towers, and support material into shoe charms. By printing the mold with PETG, it prevents sticking with PLA, allowing for easy molding.
The part that attaches to the shoe is 3D printed separately with PLA and insert-molded, ensuring both functionality and the ability to mold PLA by melting it.
There are two versions available: one that fits into holes like Crocs' Jibbitz and another that threads through shoelaces.
Instructions
Printing the Mold
Use PETG filament to print the mold with a layer height of 0.12mm or less. Ensure that the infill is set to 100%. The mold material should be non-fusible with PLA, so polycarbonate or similar materials are also acceptable.
Printing the Insert Parts
Print the insert parts with PLA filament. There are two versions: one for Jibbitz-style charms and one for shoelaces. The insert parts have holes to allow melted PLA to flow in, ensuring they stay in place after molding.
Applying Release Agent
Spray a release agent, such as silicone spray, onto the mold. While it is possible to demold without a release agent, it will be more difficult.
Fitting the Insert Parts into the Mold
Fit the printed insert parts into the mold. For the shoelace version, make sure the holes are aligned vertically.
Measuring the Waste Material
Measure the required amount of waste material.
The required amount is engraved ;n the mold, but here is a quick reference:
- Bambu Logo: 1.6g
- Star: 1.7g
- Clover: 1.3g
- Cloud: 1.6g
- Circle: 1.5g
- Poop: 1.5g
- Heart: 2.0
If in doubt, it’s better to use a little more material to ensure proper molding.
Caution
From this point on, you will be dealing with melted resin, high-temperature tools, and possibly sharp objects. Always wear gloves to prevent burns or injuries. Use heat-resistant gloves made of silicone or leather, and consider using inner gloves for additional protection.
Melting the Waste Material
Heat the PLA to approximately 230°C using a soldering hot plate or an oven. A cup-shaped silicone mold can be handy. Melting large pieces of waste material can take time, usually around 5 minutes. Flatten any bubbles that form using a spatula. You can create a nice marbled pattern by kneading the material, but be careful not to over-knead as the pattern can disappear.
Compression Molding
Form the melted PLA into a ball shape within the silicone mold. Once it cools slightly, you can shape it into a ball with your gloved hands (be cautious of burns). Place the PLA into the mold and apply pressure using the mold itself. Hand pressure is usually sufficient. Avoid using vices or similar tools, as they may cause the mold to adhere too tightly and damage the mold or make it difficult to remove the charm.
Demolding
Once the mold has cooled sufficiently, remove the charm. A utility knife can be helpful for removal, but be careful to avoid injury.
Finishing
Wipe off any release agent and remove any burrs using nippers or a file. Thin-blade nippers used for plastic models are recommended for clean cuts.
Enjoy!
Create cool charms with ease and enjoy the process of recycling and crafting!
