The goal of this project was to practice production level prototyping by making a silicon mold and acrylic resin casts with this mold. For this project, I will be adding clay embellishments to a wooden boomerang.
I then traced the shape of the boomerang onto a sheet of foam core and used it to construct a box around it with foam core and hot glue.
I then used hot glue to seal the edges to prevent leaks while the mold sets.
Next, I hot glued the boomerang to the bottom of the box, making sure it was as flat as possible. I also used Mod Podge to seal the clay embellishments.
I used SuperSeal™ Sealing Agent to seal the porous clay and wood (so the silicon will not soak in) and let it dry for 1 hour. Next, I used Ease Release™ Release Agent to ensure the silicon will peel off easily when the mold is finished setting.
To pour the mold, I mixed equal volume parts of Part A and Part B of the OOMOO™ Silicon Mold-Making Kit together and mixed them thoroughly.
I poured the silicon mixture into the box until it was filled and waited 6 hours for it to cure fully.
Once the mold was cured, I peeled the foam core box off. It appeared as though some of the silicon had leaked underneath the boomerang, so I used a utility knife to cut away the flashing and peel the boomerang out.
The mold captured the details from the clay embellishments really well.
Liquid Plastic Casting
I mixed together Parts A and B of the Smooth-Cast Liquid Plastic and poured it into the mold and let it cure for 4 hours. I put baby powder on the mold before I added the resin to make sure it would come out more easily.
I made three more plastic casts of my boomerang and used different paints to decorate them and elevate them to more production-level pieces.
