Make Candles With a 3D-Printer and Recycled Crayons





Introduction: Make Candles With a 3D-Printer and Recycled Crayons

About: I am a passionate inventor who is always thinking of new ideas and making them a reality. I do not attend MIT, that is just where I want to go when I grow up.

The possibilities of what you can do with a 3D-Printer are limitless, and in this project you will further learn that the sky is the limit by making recycled crayon candles with a 3D-Printer. These are great for emergency situations, as they do not require any special materials, and take less than an hour to make.

Step 1: Materials

For this project, you will need: 10-15 crayons, candle wick, and three Dixie cups.

Step 2: Print the Mold

First, 3D print the mold attached. There are several different shapes you can print, I printed the cylindrical mold.

Step 3: Unwrap the Crayons

Next, unwrap all of your crayons. An easy way to do it is to slice down the middle with a knife, and peel off the wrapper.

Step 4: Microwaving the Crayons

Take your crayons and break them up into smaller pieces. Put those pieces into the three Dixie cups, and microwave them in one minute increments until the wax is melted.

Step 5: Making the Mold

Now, pour the melted wax into the mold. Place the wick in the center of the mold, and place the entire mold into a freezer until it hardens.

Step 6: You're Done!

Lastly, all you have to do is light the candle, and you are done!

    Has someone tried to use them with a hot glue gun?

    instead of the glue feed a crayon thru a hot glue gun?

    I do not know, but that is a good idea! You would have to look at the melting temperature of the wax as compared to the hot glue though...

    according to the net
    Crayons begin to soften at around 105 degrees Fahrenheit and they have a melting point between 120-147 degrees Fahrenheit.
    art/craft type glue guns:

    high temp guns =385° F
    low temp ones = 250° F
    its not that much i just have to find a cheap hot gun to experiment on

    No problem, that is a great idea! I am glad it worked out. When you are done, you can use different color crayons and make cool designs with them!

    Also, there is a hot glue contest coming up that you can enter it in...
