I have been leveling up in a lot of areas, including Analog LED circuits lately. I thought I would try something a bit more crafty tonight and cast an R2-D2 head from the mold that I have created. I derived the original Droid from a 3D print I created and cut the head off.
Smooth-On brand ReoFlex 30 (to create the mold)
Smooth-Cast 300 to cast the part from.
2 hefty brand drinking cups
2 plastic forks
Casting Craft Mold Release
Step 1: Step 1, Prepare the Mold
Make certain that the mold is clean and dry before you begin. Add mold release agent, allow to dry and then add a second spray, allowing to dry.
Step 2: Step 2, Mix the Smooth-Cast 300
Shake the bottles vigorously. Mix the Smooth-Cast 300 in 1:1 ration part A to Part B. Stir with a plastic fork, then pour into the mold.
Step 3: Step 3, Allow to Set Up and Then De-Mold
Allow to set up and then De-Mold. Give the product about 10 minutes within the mold, and it will heat up and become a solid object. Wait an extra 5 minutes after it becomes solid and then pull at the edges of the mold to remove the object.
You may now paint the R2-D2 head you have created, enjoy!
