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.

Thank you for watching. We have lots of other unique videos, so please subscribe, sign up for our free e-book at ComposiMold.com, and let us know what we can do to help you with you mold making ideas.

Make Your Own Soft Bait Fishing Lures with Mold Making and Casting

Now you can make your own lures. Mix and match heads, bodies, and tails to create the perfect lure for your angling needs. Then make a mold of your unique lure shape and cast with the included Soft Bait Rubber. The mold Putty is re-usable, so melt your mold and make as many different shaped lures as you want.
To start making your own soft bait lures, you can use the shapes we provide, but when you’re ready you can expand into almost any shape.
Supplies Included:
  •  ImPRESSive Putty (You Press it over your objects to mold…get it? And it’s re-usable for dozens of molds. Impressive, we know.)
  •  2 part fishing lure Soft Bait Rubber (non-PVC based). Enough rubber for up to 20 rubber lures
  •  9 interchangeable fishing lure pieces for over 50 unique lure shapes.
  •  Gloves, stir sticks, mixing cups, and instructions.

MIX AND MATCH HEADS, BODIES, AND TALES FOR 50 COMBINATIONS OF CUSTOM SOFT BAIT FISHING LURES

MAKE THE LURE SHAPE AND MOLD
  1. Create a truly unique lure by choosing one head, body, and tail from the included shapes. You can make your lure longer by using 2 body pieces instead of 1.
  2. Use a dot of hot glue to hold each one together. Scrape away any hot glue along the seam.
  3. Heat the ImPRESSive Putty in the microwave in 15 sec. intervals until dough-like with no lumps.
  4. CAUTION HOT: Let stand for 10 minutes until temperature is comfortable to handle.
  5. Place your glued shape on a flat surface and PRESS the ImPRESSive putty onto the shape.
  6. Let Putty cool at room temperature until firm to the touch or 15 minutes in the freezer.
  7. Remove original shape by flexing the Putty away from it and pulling it out.
CAST THE LURE, then Cast your lure.
  1. Thoroughly mix Part A and Part B of Soft Bait Rubber in equal portions by volume.
  2. If you choose, you can add any dyes, fillers, glitters, scents at this time. IDEA: Add crushed up pieces of Styrofoam to decrease weight of lure or add dry sand to make it more dense. Resin Colorants and Glow In The Dark Powder sold separately.  
  3. Wipe any Activator off the inside of the mold with a paper towel or cloth before pouring your Soft Bait Rubber in.
  4. Pour your Soft Bait Rubber into the mold until it is flush with the top of the mold. Tap mold gently to release any air bubbles.
  5. Let the resin cure in the mold for 5-10 minutes or until rubbery to the touch.
  6. Flex the mold away from the casting to remove your one-of-a-kind soft bait fishing lure.
  7. Try it out…Go fishing.

 
CAST MULTIPLE LURES OR RE-MAKE YOUR LURE SHAPE
You might want to make a couple of the same lure just in case your neighbor decides to help himself to your prize winning lure. So repeat the casting process above to create multiple lures in that configuration.
OR
Break the lure shapes apart by slicing through the cooled hot glue. Scrape the cooled hot glue off of the pieces and rearrange them into a totally different lure configuration. Re-Melt the ImPRESSive Putty mold and repeat the process of creating your mold and castings.
SAFETY: ImPRESSive Putty is hot when melted and can burn. DO NOT handle straight out of the microwave. Let it stand until cool enough to handle comfortably. ImPRESSive Putty is not certified for use with edible materials. Leaking Activator from Putty can stain furniture. Store in an airtight container. Intended for ages 10 and up. Do not eat the Putty.
Soft Bait Rubber:  The soft casting rubber is a two part silicone casting resin with very low hardness (Shore D of 5) formulated to attract really good looking and big fish. While still in liquid form, the Soft Bait Rubber should be kept away from your skin. Use gloves. Do not eat or drink. 
Please do not litter. Please do not leave your rubber lures in the water or fish. The lures are not biodegradable.

ComposiMold is Your Tool for Duplicating Almost Anything

Mold making is a process that enables you to duplicate parts that are broken, add new parts in different materials, or just make more copies of an object, and ComposiMold re-usable mold making materials are the tools that allow you to duplicate what you want, when you want.

Like a tool, like a saw, like a router, or 3D printer; you don’t use it once and then throw it out. ComposiMold is there for you, now and tomorrow. Unlike other mold making materials that are used to make one mold, ComposiMold and ImPRESSive Putty can be used dozens…maybe 100’s of times. It is your mold making tool. Your duplicating tool.

In many instances instead of buying a new part, you can make a new part. In instances where you don't like a part or it breaks, you can make something new. If you want a new piece for your art, you can duplicate it.

Video of making a new part for a Powered Parachute

So for hardware, hobby, craft, arts, and prototypes for industry: The ComposiMold products are ready to help you make what you want, when you want. For fast molds, ImPRESSive Putty is ready: heat, press, and mold. So if you break a handle, need to fix your trim, or want to make a new Monopoly game board piece.


Stop thinking of mold making materials as a onetime use material. It’s not! Unlike silicone, unlike urethane, unlike alginate, ComposiMold and ImPRESSive Putty are re-usable molds.

Plastic Casting and Rubber Casting

Here we describe the plastics and rubbers as basic types of material to use as a casting material:

Plastic casting parts
Plastic parts cast in molds
 Rubber or elastomeric: Rubbers range from super soft to hard, almost like plastic. The hardness are ranked from Shore OO-5, very soft like a rubber fishing lure to Shore A to Shore D of 80 or 90, which is hard like a skateboard wheel.  Rubbers can be silicones, urethanes (also called polyurethanes), latex, PVC based, and others. The two recommended for most castings is urethane rubber or silicone rubber, and there are a lot of different options based upon the other properties you are looking for such as amount of elongation, strength (typically listed as tensile strength), tear strength (how easy it is to rip after a rip has started), color and feel, and how easy it is to make.  Thermoset resins require mixing two parts together and depending on the resin, this ratio will be different. If the instructions for a particular resin do not say specifically, they are typically mixed by weight, although many will give the mixture ratio as both by weight and volume. Each one of those rubbers will be discussed in future blog posts.
Rubber casting of an X, made with silicone rubber 

Plastic: we hear a lot of people ask for plastic that acts like the plastic of an Army soldier.  Army soldiers that you buy are made from thermoplastic resins, but you will likely be casting with thermoset resins. The difference is thermoplastics are melted into a thick goo and squeezed into the molds. Whereas the thermosets are two part resins that are mixed together as a liquid (or paste) and poured into your molds. It’s a lot easier to make your own castings with thermosets because it can be poured. Thermosets, after they are cured, cannot be re-shaped.  Thermosets can have very similar properties as compared to thermoplastics.
Different types of plastics include urethanes, epoxies, polyesters, vinyl esters, and others. For home or small industrial, the main plastic resins are epoxies and urethanes. Polyesters are much cheaper, but the smell and toxicity are extremely detrimental. It is also more complicated to use.


Rubber Casting Material

“Exotherm” of a Casting Material is the heat of reaction produced as a resin or rubber cures. If the casting is thin then heat is easily dissipated in the mold, but thicker pieces will create more heat. To compensate, large pieces can be poured in intervals or add fillers to the casting material.

5 Mold Making Techniques to Rule to World

How to Use Different Mold Making Methods
How to Use Different Mold Making Methods
The purpose of mold making is to duplicate your creations either in the same material the original is made in or into another material. But first you have to make your mold. The mold making process is very versatile, so you can choose how you do it based upon what your master object is shaped like. Typically, you don’t want to make your mold any more complicated than you need. Here are 5 techniques that can be used:
1.       Pour Block mold method: This is the go-to method. Because ComposiMold is clear. You can always make it into a cut block mold. The technique is a simple: place your master into a mold box and pour ComposiMold over it. It gives you a sense of what the mold will look like, and you can always re-melt it and make it a different way.  If your part is lightweight and will float in water, hot glue it to the bottom of the container.

Pour Block Mold Making Technique

2.       Cut block mold: Almost as easy as the pour block method. Make a pour block method and then cut out your master where you want the parting line to be. Because ComposiMold is a clear rubber that you can cut with scissors or a knife, we just pour it over the part, allow the ComposiMold to cool, and cut the mold in half. Sounds easy, and for the most part it is. You will still have to worry about where to make the parting line and keeping the part together while casting the new piece. There is no reason why more complex molds with three or pieces cannot be made using this same techniques.

3.     The Press Mold: With ImPRESSive Putty, just press your Putty over the part you are molding. The nice part about the rubber molding putty is that you don’t need a mold box. However, you will lose a little detail on the corners.
Press Molds Technique

Press Molding Technique
 The Brush-on Mold or Paint on Mold: Paint-on molds are made by painting the molding material directly onto a model’s surface. The advantages of a paint-on mold are that it is possible to use less material and you can mold parts that you could not do with a typical molding process. An example where you may need to use a Paint-on mold is making a mold of something attached to a wall.

5.       2 Part Mold Making Method: In many cases, it is best to prepare the mold in two parts. This may be because there are specific undercuts that you need to mold around, you want to make a parting line that is not straight, or you want a three part mold. The two part mold is well suited for dramatic undercuts that would leave spaces or voids in your mold. Use clay or polymer clay to build up around the figurine. Build up the area to the point where you want the parting line in the mold. This parting line is selected to allow the mold to be separated easily. After the clay is completed, lightly cover the master part and clay with a mold release. Pour ComposiMold over the Master and clay to make the first half of your mold. When the ComposiMold has solidified, pull off the first half of the mold, flip your Master and pour ComposiMold over the part again being sure to have mold release in between the layers, and in larger molds chill your first ComposiMold half before pouring the second. After the second ComposiMold half has solidified, pull it off of the Master. Pull out the Master part from the mold. You are now ready to make your casting.
