Use Sugru to Make an Ice Mould

Introduction: Use Sugru to Make an Ice Mould

The basic steps to make an ice mould out of Sugru are

1. Design the pattern
2. Cut the pattern into acrylic
3. Stuff the sugru into the pattern
4. Remove the pattern

Step 1: Design the Pattern

Using your favourite CAD software, design the pattern you want to have as part of your ice cube.

Since acrylic is much thinner than the final size of the ice cube mould, design it in layers. We had 3 layers... one solid circle and two circles with our makerspace logo cut into it.

Step 2: Cut the Pattern Into the Acrylic

Having a cute kid watch the process will only make the final result better.

Step 3: Stuff the Pattern With Sugru

Stack the various plates of acrylic and glue them together. Then pack the sugru around it and inside the holes.

Step 4: Remove the Pattern

Wait for the sugru to dry, remove the acrylic, and fill with water. Freeze.

    It's worth mentioning that some of the food-safety qualities have not been thoroughly certified. For those who are cautious about such things, I'd recommend reading the tech sheet before making ice or any implement that comes in direct contact with substances that will be consumed. They claim that it is completely inert when cured. However, I think it is best to exercise some caution since this material is still relatively new and tests are ongoing.
