Molds

Make a 2cm guide and pass the cutter without reaching the bottom, just to create a trench and be able to fold the acetate in the opposite direction. To make the molds you will need:

-2mm thick acetate -Ruler -Cutter -Adhesive tape

MOLD Then cut 2cm x 2cm squares at the ends of each corner, and reserve them for later. CASTING MOLD

31 MOLD CASTING MOLD Acetate costs around €1.50 (the year 2022) so it is a fairly cheap and easily reproducible shape. To have large plates of bioplastics since the acetate prevents it from deforming when it dries. Use the adhesive tape, preferably transparent because that way you can see inside the mold. Glue the corner joints and reinforce all the sides where the acetate has been folded.

To calculate the amount of liquid that a mold can contain, I use this formula:

3 Volume= length x width x hight = Side CASTING MOLD MOLD
