How to Make Unique Soap Molds, Trump Soap on a Rope

Soap Molds that you make yourself.

Experiment!  Today we are going to show you how to make a unique soap mold using a 3D printer and ComposiMold. We downloaded a design of the Bust of President Trump from Thingiverse that was designed by CU 3D and threefer. It took several tries to print before we were ready with our Master shape. To make the surface smoother than what you get with the 3D printer we washed the shape in acetone.

To make the soap mold: we hot glued the Trump Bust to the bottom of a cup and then sprayed it with Bubble Buster.

We melted the ComposiMold-Flex  Re-usable Mold Making Material  in the microwave for about 1 minute using a 40 oz. container to obtain enough melted molding material. This was poured over the master part.

The mold solidified in about 30 minutes in the freezer. The original part was extracted from the mold, and we now have a unique soap mold.

In this project, we are making a Soap on a rope, so a piece of rope is placed into the mold. The soap is melted in the microwave and then poured into the chilled ComposiMold Mold.

Be sure the soap is cool prior to pouring into the mold.

We then extract the soap from the mold by peeling the ComposiMold away from the soap and then pressing the shape out. If necessary, use scissors to cut a parting line.

While 3D printing the bust, we had a print that did not complete, which gave us another idea for
adding a sponge to the top of the bust. So here is another mold and soap we
made of President Trump. The mold making process is the same.

You will notice that the head was facing to opposite way in the mold because we wanted his head to be open when we poured in the soap.

The sponge is cut to fit the shape of his head.

We added a piece of rope to the sponge so it will stay on his head better.

We then poured in the melted soap and placed the sponge on to his head.

This mold was placed in the refrigerator for about 30 minutes before pulling the soap out of the mold.

We carefully pulled the ComposiMold away from the soap, and we had our very own soap of the President of the United States.

The Science of Why We Can Pour Hot Casting Materials into Cold ComposiMold

Making a mold with ComposiMold is easy. Simply, bring the temperature of ComposiMold above 135 F and pour! To solidify, just cool to room temperature.

Due to thermoconductivity, you can still use casting materials in this mold that are above 135 F and they won't destroy your mold. Rubbers, such as ComposiMold, have low thermoconductivity. This means it takes longer for the heat to travel from hot casting materials into the ComposiMold mold. The hot materials will set up before heating the ComposiMold.

You can actually pour casting materials into ComposiMold up to about 180 F even though ComposiMold melts at about 135 F. You can do this by chilling the ComposiMold mold first. For example, beeswax makes a great candle, but it melts at 145 F, so you need to cool the.ComposiMold mold by placing the mold in the refrigerator or freezer and then pouring in the melted beeswax.

So by chilling the ComposiMold, it takes much longer for the mold's temperature to reach its melting point. However, if you chill it to 30 F, it must heat up over 100 degrees before it melts.

The casting material, such as the wax or soap, only has to drop its temperature a few degrees before it begins to solidify. Also, waxes and soaps cool from the outside to the inside (unlike metals that cool from inside/out). So as they cool you create a barrier of wax that also helps protect the ComposiMold.

Be sure to chill the mold prior to each casting made. This will ensure that your mold doesn't get destroyed and that your mold making and casting experience is a success.
