In October of 2010, Instructables member mikey77 published How To Make Your Own Sugru Substitute. His creation gave us what he called "Oogoo", a silicone / cornstarch mixture that is cheep, easy to make and handily rivaled it's marketed predecessor Sugru. The last few months have shown us a rising popularity in the use of Instamorph in the maker arsenal. This instructable will introduce you to how well these two media work together, in that they do not work together at all. The result is a quick, easy-release and highly detailed mold making method. Here's how it works:

Step 1: Gather Your Media.

What you'll need:

-Oogoo. Follow mikey77's recipe or your own favorite mixture, if you have one.

-Instamorph. Generically, it's thermoplastic. It also goes by Shapelock or Polymold.

-Heating vessel and silicone rolling pin.

Step 2: Find Something to Recreate.

I chose my thumb. Just because. That's why.

Step 3: Ready the Instamorph Mold.

Heat a generous amount of Instamorph. My favorite way to heat Instamorph is through hot water. Use the rolling pin to roll out a sheet of Instamorph about 1/16-inch thick, big enough to envelope what ever you want to mold.

If you choose to make an imprint mold, form a block thick enough to take the impression of your object.

Reheat the slab of Instamorph to make it pliable. If you are using your hand like me, make sure the Instamorph sheet is not too hot. Luckily, Instamorph becomes very workable at mild temperatures. Tightly pack the plastic around your thumb to pick up all the lines and wrinkles. You can run the mold under cold water to set the outside. Let the inside cool for 20 minutes and carefully extract your thumb so as not to "blur the details".

Step 4: Mix Your Oogoo.

A trick I have learned is to fill your mold with water and empty that water into your mixing vessel. This will give you a sense of how much Oogoo you will need to fill your mold. Empty out the water and mix your Oogoo ingredients.

Use a mixing rod (or barbecue skewer) to push the Oogoo into the spaces inside the mold, making sure to at least coat the walls of the mold.

Side Note: Some recipes call for types of paint thinner or Naphtha solvent in order to thin the unset oogoo and make it more workable. Experiment with these recipes to find what works for you and fulfills your mold making needs. This instructable might be helpful: Fun With Oogoo: Make A Folding Indoor Frisbee

Step 5: Finish.

Allow Oogoo to set for a few hours. Once set, Oogoo releases from Instamorph quite easily. If you are molding something deep, (like a thumb) you may want to run hot water over the mold to soften the Instamorph and peel it away from the Oogoo. You will destroy your mold this way, but with the rework-ability of Instamorph, creating another mold takes very little time.

As you can see in the result, both Instamorph and Oogoo have great detail capturing ability.

Step 6: Going Further.

Enjoy!

<p>This really is awesome. Oogoo is cheap and instamorph is reusable. Great combination. I wonder, I do have some Radio Shack brand instamorph stuff, I'm very curious as to whether or not the instamorph flows if its hot enough. I'm thinking maybe using it like lost wax casting. Thoughts?</p>
<p>Hm, I've heated Instamorph up to boiling temperatures. It never flows like melted wax. Even with a heat gun it just bubbles then burns. I've done lost wax before, using hot metals to fill molds, I honestly dont think Instamorph is what you're looking for here. These are just my thoughts. But it does sound interesting to know what the limits are to this stuff. Sounds like a great experiment. Post your findings if you do it!!!</p>
<p>most modleing clay will the never dry stuff you can heat it to like 170 i think and it becomes pour-able</p>
I had given up all crafting about 5 years ago due to depression. Thank God, I'm better now &amp; found myself wanting to get back into crafting again! Needless to say, I was clueless as to what the heck all this instamorph stuff was or this oogoo, sugroo stuff was either! Due to this excellent tutorial, now I know &amp; I can't wait to get started with this stuff!!!
<p> I have had many periods of severe depression and live with constant mild to moderate symptoms, so I know what you mean. Sometimes just getting out of bed and getting dressed is an accomplishment. But I am beginning to find balance and my creativity is slowly returning. And Instructables has been really helpful in giving me the inspiration and drive to at least try to do things, even if I don't always succeed. The biggest problem I have now is that I want to do *everything*. I just found out about Oogoo yesterday and I read a comment today that jogged my memory about Instamorph, which led me here, and now I desperately want to get started with both, but I haven't even finished my current projects, and I already have several others planned.... there just aren't enough hours in the day. </p>
<p style="margin-left: 20.0px;">This is the best comment I have ever gotten. I am certainly glad you have found your way back to some kind of maker-space. Making things has brought me immense amounts of joy and pride. It has helped me make strong connections with people, many of whom are now great friends. Instructables is a fantastic community of makers who cant wait to help you learn and do. There is allot of love here. Thank you for reaching out, even if it's &quot;just a thumb&quot;. : )</p><p style="margin-left: 20.0px;">There are many more instructables here on Instamorph and Oogoo, all great projects and techniques; lots of people willing to share their ideas and discoveries. Me as well.</p>
<p>Super fun! InstaMorph and oogoo: Old fashioned making + modern materials = 1 hoot after another.</p>
<p>Thank you!!</p>
So awesome. Thanks for the idea.
<p>glad you liked it!</p>
<p>Very cool! And unlike most molding materials, you don't have to worry about wasting the material to make just a single molded part.</p>
<p>There's another product out there called &quot;ComposiMold&quot; that is similar, in that it can be re-used. I saw them at Makerfaire NYC. Thanks for commenting! </p>
<p>Excellent work! I just got some instamorph for the first time, and I'm excited to start using it. This is great info, thank you!</p>
<p>Thanx for the comment! It's great stuff. Have fun!</p>
