13. Molding and Casting

I will be using this:

Want to make mold something for my daugheters birthday who is turning 1 year old in June

Tinker Cad

I used cylinder and sphere and text to make the design

3D printed mold

STEPS

Mixing

Safety Measures Working with chemicals you must be protected, i used face mask and gloves

To mix with the silicon, i prepared a container,

Weighing the base silicon

Before I measure the base silicon i ensured, the container is tared while empty (zerod)

Measured small amount that can fit my 3D printed mold

Weighing the hardener

I weigh the base silicon, and calculated its 3 % to be used for the hardener. I measured 3% of 156.02(base silicon) and that is what i used for hardener to mixx.

Sucking the air gaps using vacuum cleaner until i see bubles coming out

After string I left it in the sun for 2 hours and got the result
