the knight chess piece mold / Chess Knight Mold

This is a mold designed to recycle 3D printing waste (PLA) into chess knights. It can process 40g of plastic at a time. While PETG can be used to print the mold, its lifespan as a mold is limited. For long-term use, it is recommended to print the mold using high-temperature resistant carbon fiber reinforced materials (such as PET-CF, PA-CF, PPA-CF). I have tested PPA-CF material, and it is very suitable for use as an injection mold, allowing for long-term use without thermal deformation. However, it is expensive.

Tools required: oven, 3M respirator, silicone baking tray, 4-inch G-clamps (3), M4 25mm screw (1, as a demolding ejector pin), flat screwdriver, hammer.

Process:

1. Place 40g of PLA in an oven and heat at 210°C for about 15 minutes.
2. Secure the mold with G-clamps.
3. Pour the melted plastic into the mold, insert the piston, and press down firmly on the piston (for about 30 seconds). (The plastic must be melted to a slightly viscous state for easy molding; otherwise, the melted plastic cannot fully fill the mold.)
4. After about 20 minutes, use a flat screwdriver to open the mold and use the M4 screw as an ejector pin to demold.
5. Remove burrs and sand the bottom with sandpaper.
