Making Lego Crayola Crayons and Other Shapes

Crayola Crayons are a great casting material. You can make your crayons into any shape. Including Lego Shapes or animal shapes. The process is very straight forward. The Crayola crayons are nice because they have reasonably good colorants added, but any other crayon could be used. A recent addition to the crayon world is the all-natural soy wax crayon.

Lego Crayons


There are two ways to make a mold of a Lego with Crayola Crayons. The first uses ComposiMold. The second uses ImPRESSive Putty molding materials. These are re-usable molding materials that can be re-melted or re-softened to make as many molds as you want. To start, let's talk about the ComposiMold:

1. Hot glue the Lego piece into the bottom of a plastic cup. Be sure the Lego is facing up. Do not have it upside down. You can also make a little mold box with other Lego pieces like we did when we made Jell-O Legos (https://composimoldstore.com/casting-material-options/#jello )
2. Melt a small amount of ComposiMold. You'll only need a little a little bit. Melt approximately 30 seconds worth in your microwave.
3. Let the ComposiMold cool a little before pouring onto the Lego.
4. Pour onto the Lego piece.
5. Let cool, or place the cup with the Lego piece into the freezer to cool fast. A mold this small will solidify in about 15 minutes.
6. When the ComposiMold is rubbery, pull out the mold and the original Lego piece.
7. Melt the crayons. Crayons do not have any water in them, so you will have to melt them on a stove. Be careful.Crayons melt at about 105 F.
8. Before pouring the crayon wax into the mold, let it cool so it's almost re-hardening.
9. Pour into the mold cavity.
10. Let cool to solidify. Give it about 20 minutes or about 5 minutes in the freezer.
11. Pull the Lego piece out of the mold.



 

You can also make the mold with the re-usable molding putty, ImPRESSive Putty instead of the ComposiMold by pressing the ImPRESSive Putty over the Lego piece. 

Other shapes that may be interesting: 
1. Making seashell shaped crayons
2. How about a starfish crayon with every finger a different color?
3. Make and mold a shape from polymer clay that is then made into a crayon.
4. Lego person (cover holes in the back of the lego person with clay first)
5. A doll's hand
6. A banana
7. Build a structure with the Legos and then mold it as a full piece.

If you want to add the connector piece to the back of the Lego crayon you can. When the crayon was is still liquid, place another lego block on to the back of the Lego mold.

11 DIY Christmas Crafts

To me, making Christmas crafts is the most exciting part of the winter holiday. Christmas crafts bring out the maker almost as much as the Halloween ghouls in the fall, but typically Christmas crafts are a touch less creepy and more festive. But don't let anything stop you from the more atypical crafts.  Anything can be much more enticing if made by you. Let's review 11 DIY Christmas crafts that are good for adults or kids. So start making those Christmas Gifts!

1
Christmas Ornaments are the obvious place to start for Christmas Crafts. Air dry clays or polymer clays can be used easily. Or you may want to try your hand at resin casting your ornament. Same mold

2.
Soaps for Christmas Gifts. You can decide if you want to do a Trump Soap or not. We used a 3D printer for this, but you can use any good soap shape, even another piece of soap.

3.
Oh! Cute Kid Pictures! Framing those should be a top priority Christmas crafts. One for each relative. We used polymer clay to make the frame and airdry clay to mold.

4.
Jewelry Making for Christmas Crafts. How to decide which color earrings? Don't decide. Make them all.

5.
Coffee mug decals crafted for individual tastes. With the ImPRESSive Putty, you can reform a decal for everyone on your Holiday list.

How to Make Your Own Coffee and Beer Mug Decals with Polymer Clay and UV...

Found the original mug with the golfing guy at a recycling shop. Now I have my Christmas gift for my uncle all done. For the morning, he will have his coffee mug with the golfer decal on it. In the evening, he will have his beer mug.

This video shows you how to make your own coffee mug or beer mug decal.




Here are the finished mugs:


You can even make your own shape. In an earlier video, we made chocolates by carving the shapes out of clay and then using that to make your chocolate bar (see below). This same process can be used for polymer clay decal molds.


Thank you.

Making Molds for Polymer Clay, A Leaf and Candle Holder

Polymer clay is a modeling clay that can be formed by hand or in these examples molded with molds. Polymer clay is well suited making art pieces and craft projects because the polymer clay is hardened in the oven to make reasonably sturdy finished parts. These “how to” tutorials demonstrate methods of forming the clay into unique shapes using molds, and we are using the ImPRESSive Re-usable Molding Putty.

The polymer clay mold making video below demonstrates the methods for making a mold and then forming the polymer clay into the shape of a leaf. The mold picks up the details in the leaf. The polymer clay push mold can be re-used or re-shaped after it has been used for the leaf. 




The second video demonstrates the methods to mold and cast a wood piece into polymer clay. This candle holder is untreated wood. This mold was made using the polymer clay push mold used in the first video. The Putty was also melted down to make the soy wax candle of the lightbulb.

The 7 Key Steps to Molding Successful Plaster Castings in a ComposiMold mold.

The 7 Key Steps to Creating Successful Plaster Castings in a ComposiMold mold.

Making a Plaster of Paris Casting in ComposiMold: 

Follow the basic mold making instructions on our mold making instructions provided with every ComposiMold to make a mold with ComposiMold. The tips below will set you up for success when using plaster of paris, hydrocal, ultracal, dental plaster or other plasters as your casting material. 

Plaster of Paris Casting in ComposiMold
Plaster of Paris Casting in ComposiMold
With ComposiMold, making molds and plaster castings is really easy. Here are seven tips of the trade:

1. Keep the plaster of paris casting material as thick as possible to ensure a strong casting. Start with a ratio of 2.5 parts plaster to 1 part water by volume and if possible reduce the amount of water. If you need more water to make it pourable, add very small amounts.

Mix ratio for Plaster of Paris
Mix ratio for Plaster of Paris 

2. Add a t-spoon of PVA glue such as Elmer's Glue for every cup of water to make the casting stronger. A bit of alum powder will also increase the strength of the plaster of paris.

3. Use talcum powder as a mold release. Sprinkle it into your mold shake it around, and then pour it out. This does two things: works as mold release and also creates a barrier so that the plaster of paris hardens in the ComposiMold. Even better, is a mixture of talcum powder (baby powder) and mineral spirits.

4. Pour the plaster into the lowest point of the mold and let it rise upward to help dislodge bubbles.

5. Large plaster of paris castings may need to be cooled. Large for plaster castings would be 500 cubic inches or so, so pretty large.Typically, plaster does not create a large exotherm, but for very large castings, this may occur. This is easy to work around by cooling the ComposiMold mold first in the freezer or refrigerator. 

6. Tap and bounce your mold when it is filled with the plaster to dislodge any bubbles to create bubble free castings.

7.  Pull the plaster of paris casting out of the mold as soon as possible and then let it cure for 24 to 48 hours before painting or sealing.

Experiment: With ComposiMold you can make lots of different molds with the same mold making material. Make a mold, cast your plaster of paris, and do it again. Simple, effective, and fun.

Plaster of Paris makes a nice casting material for teaching mold making because it is relatively inexpensive. It can also be painted, sanded, and fixed easily.

This is NOT for Making Your Own Silicone Molds

Have your ever tried to make your own silicone molds? If so, I'm sure you have made many a mold that did not work the way you wanted it to. Did your part float? Did you have bubbles? Did you want to make changes and realize that the silicone is a two part molding material that can never be changed after it has cured? Making silicone molds takes skills and knowledge you can't get without experimentation:

  1.  How do you pour the silicone?
  2.  How do you keep your part from floating?
  3.  How will you make your mold? 2 parts? 1 part? Brush-on? Where does the parting line of your mold go?

Silicone is an amazing rubber material that is a strong, durable rubber. After the silicone has cured, it will remain a rubber forever. My advice is to keep the silicone for your castings, and use a re-usable molding material for your molds.

I say this, of course, because I'm biased and think that ComposiMold and ImPRESSive Putty are better choices for making your own molds. Whether you are learning how to make your own molds or are already skilled (and already spent tons of money learning :) ), these re-usable molding materials can help. ComposiMold and ImPRESSive Putty are re-usable molding materials that can be re-used Any Time You Want. If you make mistake, make it again. If your mold starts to get old, make it again. If you change your mind, make it again.


Silicone molds will last for years. If you're into nostalgia you may like that. But you can also keep ComposiMold molds for years if you'd like...keep them in a ziplock bag and out of the sun and they'll last as long as you like.

Silicone molds will not allow you to make changes, fix mistakes, or experiment. Better materials exist.

ComposiMold and ImPRESSive Putty. Give them a try.

Restoration of Building Column with Re-usable Molding Putty

Many older buildings feature beautiful and historical designs but require updates and restoration. To restore and preserve these fetatures and designs can be performed with our Re-usable Molding Materials. 

We were asked to support the historical renovations of some columns for a historical building nearby. Initially, the forms were going to be 3-D printed, but there was a fear that the polymers used in the 3D printer would not be able to handle long term exposure to the cold of a Northern (Maine) climate year after year. The other alternative was to remake the wooden components from scratch, but that would require a different level of effort. 
So the simple solution was to mold the pieces. Two different pieces made up the bottom of the column. A total of 32 pieces were needed to fit around 3 columns. Ten pounds of ImPRESSive Re-usable Molding Putty was used for these two components to make 4 molds. The advantages of the ImPRESSive Putty is that it is re-usable. So like any other tool that the carpenter uses for the construction or reconstruction of a room or a building or a porch, the Putty is used when you need it. The ImPRESSive Putty melts in a microwave, low temperature oven, convection oven, or slow cooker. When it is melted it is a soft putty that is PRESSed (thus the name :)) over the part.
The ImPRESSive Putty cools to solidify, so an hour in the freezer gave us a mold. Several times we decided we did not like how the mold came out, so we re-melted the mold and made it again. 
Woode Restoration with molds
We used ComposiCast resin with joint compound and plaster as fillers. ComposiCast is an epoxy resin that has reasonable strength. We also added a UV inhibitor. The resin ratio is 1:1 by weight or volume. ComposiCast also has a very wide range so you don't have to be that accurate with the ratios. The filler helped reduced the cost and the exothermic reaction. We added 50% filler to the resin mixture by weight. 
We planned on 10 hours cure time, but it ended up taking about 7 hours to become cured enough to pull the castings. This allowed us to do 2 pours per day. 
After this construction project was complete, the ImPRESSive Putty can be used for the next project just be re-melting and re-using. It is also excellent for fixing fixture on walls and ceilings by pressing over the fixture anytime you need to duplicate a shape.

We need your support! Kickstarter for Food Safe Molds

ComposiMold, the makers of re-usable mold making materials, is announcing today that it is raising funds to complete the development of the first food safe, re-usable mold making putty. This eco-friendly molding putty is designed to make the process of making your own chocolate molds easier than anything else available. With it you can duplicate any object into edible treats.


ComposiMold is beginning the campaign to raise $4,000 in funds through an online funding platform, Kickstarter (https://www.kickstarter.com/profile/composimold). Kickstarter is a way for people to pre-order the invention prior to it being commercially available. This enables ComposiMold to complete the testing and produce the first batch of their latest DIY material that is going to change the cake decorating and chocolate making world.

The ImPRESSive Putty has been called the “3D printer for the rest of us” because it is so simple to use. Just heat, press, duplicate, and then whenever you want to just re-melt to re-use. What you make is really up to the user.  And now you can make shapes into edible treats like chocolate, fondant, gelatin, gummies, gumpaste, butter, and more. Examples include:
·         Duplicating toys like a lion’s head into chocolate (more interesting than a bunny!).
·         Making a fondant cake wrap from lace
·         Taking a 3D printed object and making it into butter.
·         Making jewelry into gelatin or Jell-O.


About 2 years ago, Shawn Lemelin and Stan Farrell were trying to develop eco-friendly polymers for use in ComposiMold, there heat and pour re-usable mold making material. At the same time, they were attempting to create a re-usable material with a higher melting temperature than ComposiMold. It was through this experimentation that the first ImPRESSive Putty was developed. This initial material was not food safe, but immediately after commercializing it people wanted it for their cake and cookie decorations.

“Almost immediately we knew we were going to need to invent a food safe version of ImPRESSive Putty.” Stan, the President of the Maine manufacturing company, says. “We were being asked by cake decorators every day. It took us another two years, but we think we have it, a food safe, re-usable molding putty.”

So what can you make with Food Safe ImPRESSive Putty? From chocolates to fondants to Marzipan, to Jell-O. Lego pieces are popular as candy. Jewelry is also used to make edible treats. Many people in the creative maker community like to make 3D printed parts into chocolates. You can decide. You can make your own molds anytime you want. Small molds can be made in less than 10 minutes. Larger molds in less than an hour.

To make this reality, ComposiMold needs to complete the testing for food safe materials, obtain correct packaging and labeling, and produce the first round of materials. The Kickstarter campaign is designed to support this preliminary work.

Best Epoxy for Plastic


When making parts with ComposiMold, many people want to make plastic parts for toy Army Soldiers, jewelry making, toys, and more. Although many resins can be used, ComposiMold has worked to provide an epoxy to work specifically with ComposiMold products. The best epoxy for plastic parts in ComposiMold is our ComposiCast because it has been designed to work with ComposiMold and ImPRESSive Putty. 

The ComposiCast is a hard plastic that mixes 1:1 by weight or volume. The ratios are very flexible making it easy to be succesful with this epoxy resin.

10 Most Commonly Asked Mold Making Questions

Mold making is defined as the process of duplicating other objects through the use of molds. To make molds you can use a variety of techniques and materials. We thought we would answer some of the most frequently asked questions on mold making here as it relates to mold making, ComposiMold, and ImPRESSive Putty.

How much mold making material do I need?

If you know how many gallons or liters of ComposiMold you need: The quick answer is that you will need 11 pounds per gallon, 2.75 pounds per liter or 0.042oz. per ml.

If you don't already know the volume of material you need, you can measure water as if it were ComposiMold as seen in this video: 




Or You can do Math!

Start by figuring out the size of your part. The easiest way to estimate is to take the length, width and height dimensions as an estimate in cubic centimeters or cubic inches. To this dimension, add an inch to each dimension and find the total area of your mold (Or use the volume of your container that you will be molding the part in) Subtract the part size from the container size and multiply by the density of the ComposiMold. This will give you the amount of ComposiMold you need.

ComposiMold has a density of 1.2 grams per cubic centimeter or 0.7 ounces per cubic inch. In most cases approximately a 0.5 inch on the outside of your mold is good to provide mold support to your mold.

10 oz. ComposiMold = 14 cubic inches 
20 oz. ComposiMold = 28 cubic inches
40 oz. ComposiMold = 56 cubic inches

Here is an example:
The part to be molded is 4.5 x 6 x 0.5 inches. I suggest about a 0.5 inch of ComposiMold around to provide support. So 5.5 x 7 x 1.5 inch container. 57.75 cubic inches of material minus the original piece 4.5 x 5 x 0.5=13.5 cubic inches. So 57.75-13.5 = 44.25 cubic inches. Convert to weight. ComposiMold has a density of 1.2 g/cc (0.7 ounces per cubic inch) so: 44 times 0.7 = about 30 ounces of ComposiMold to make this mold. ComposiMold is also nice because if you decide to make the mold bigger or use too much material, you can just reuse it later, so it is not just wasted unlike most mold making materials.

For press molds like ImPRESSive Putty, you need to estimate the surface area. Typically, you want about a 1/4 inch to a half inch of mold making putty around your part. You can get a quick estimate of the surface area by placing a piece of paper around your mold. Measure that area and then multiply it by a thickness. 

And the advantage of ComposiMold and ImPRESSive Putty is you can re-use it, so you aren't wasting any material if you melted too much. 

What can I cast into the molds? Can I mold metal?
You can use many casting materials in the ComposiMold rubber molds including:

plaster or gypsumconcrete:Use as thick a mixture as possible to give stronger castings: Because ComposiMold is biodegradable, if the solution is too liquidy, you may damage the mold details.

Silicone: Use either tin cured silicone or platinum cured silicone rubber. Both work great as rubber casting materials.


plastics:look for urethane or epoxy resins that cure slowly to reduce the heat created during curing.

chocolate:works awesome: white chocolate, dark chocolate, tasty chocolate

candle wax, and soap! Freeze the ComposiMold first so that the wax or soap will cool faster than the ComposiMold can heat up.

Many others.

ImPRESSive Putty works with the same materials plus fast curing urethanes, and low melt metals. ImPRESSive Putty is not certified food contact safe like ComposiMold.


ComposiMold melts at 130 F. Any casting that creates heats up to more than 130 F can melt ComposiMold, but there are many ways to get around this limitation. Examples include:
  • Pouring in intervals so each pour only creates a little heat and the heat can dissipate
  • Adding filler such as dry talc, other dry powders, wood chips, etc. to the casting material so there is less casting material to create heat
  • Freeze or Cool the ComposiMold or ComposiMold-Firm (PowerMold) prior to pouring in the casting material. The heat during curing can sometimes be removed faster than the ComposiMold can heat up. This is a great way of doing candle wax and soaps.
  • Using a brush-on mold making material such as latex, urethane rubber, or silicone to create a barrier. This also helps create molds that can last for many more castings. This allows 90-95% of the mold to be reused whiles still getting the benefit of longer lasting molds.

How do I add colors to my casting materials?
We have special resin colorants that work really well with most resins. In epoxy, you can use a little acrylic paint and even a little food coloring as well. We also have glow in the dark colorants.

Can I make molds of body parts? Can I make body molds?

ComposiMold is a little too hot. ImPRESSive Putty will work, but is slower to cool unless you can put it in a cool environment. We have body molding powder that will work as well to duplicate body parts, but it typically can only be used once. 

Is it safe for food molds like chocolate molds?
ComposiMold is certified food contact safe. So yes, chocolate mold making is awesome. The chocolate is also re-usable, unless you eat it.

How do I make a mold?
Download our free mold making instructions e-book to learn more. We also have tons of videos. Start simple. Remember, ComposiMold is re-usable, so as you get more comfortable, you can build up to more complex molds.

What mold making material do I use?
We actually have 3 different ComposiMolds:
·         ComposiMold-Flex: for waxes, soaps, and chocolates (shore A hardness of about 3-5, soft and very flexible to make it easier to flex the casting out of the mold)
·         ComposiMold-Original: a good compromise of firmness and flexibility so you can still easily remove your parts (shore A hardness of about 10 at room temperature)
·         ComposiMold-Firm: firmest, mostly for polymer clay push molding. (shore A hardness of about 20)


We also have the ImPRESSive Putty, which is pretty firm as well.

HOW MANY TIMES CAN ComposiMold BE RE-MELTED AND RE-USED?
With care, (not burning it and filtering debris from it) there is no limit to the number of times you can reuse ComposiMold or ComposiMold-Firm (PowerMold). They have been certified to conform to ASTM D-4236 for reuse more than 35 times.

How to get a smooth finish on your castings of 3-D parts


Smooth 3-D printed parts are difficult because of the way most 3D printers print. Each layer builds up on the previous layer so the printed part is a combination of lines or ridges. Smooth 3D printed parts make smoother, more finished castings. Whether you are making more parts in plastic, soaps, candles, or chocolate; smoother master parts will help.

For acrylic 3D printed parts or ABS plastic, use acetone that you can find at the hardware store. It is also sold as nail polish (amazing to me that acetone is acceptable for putting on your hands!).  Acetone smooths your part by basically putting the ABS into solution, and then drying away, leaving a smoother finish.
So to use, just smooth on the acetone onto your 3D printed part. You can do this by dipping, brushing, wiping. Rubber gloves is highly recommended. And definitely do not breathe the fumes of the acetone. It is not healthy for long term exposure.

If you dip your part in the acetone, as we do in the video below, be careful about leaving the acetone inside the 3D part. If the acetone cannot evaporate, it will continue to dissolve your creation.


You can also use your covered fingers to smooth out the ridges.

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 threeferIt 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.
