| Status: | experimenting stage |
| Initiator: | Massi |
| Materials Used: | various thermoplastics |
| Tools Used: | plastic shredder, drying oven |
Massi has begun experimenting with plastic beams made from self-shredded recycled plastic flakes.
Open Mold Method
To make beams without special machines, you can use a mold which is open on one of the long sides. Molten plastic is filled in and pressed into the mold with a matching "fourth side" piece.
- rough process
molten plastic in a baking pan
filling the mold with heat-resistant gloves
not ideal, but allows for longer molds: diagonal mold heating
