Ever fancied making a carbon prototype or one off creation? Don't have thousands of pounds to spend on industrial equipment? Compound 9 is the radical new substance which allows you to make super strong, lightweight carbon shapes, models and prototypes using only your bare hands if needs be but also conventional tools if you want to get really fancy.

Compound 9 comes in granular form, and to get started all you need is a bowl of hot water. Pour the granules into the bowl and as long as the water temperature is between 50° and 100°, it will turn into a soft, pliable putty for around two minutes. Need more time to fettle? Just dunk it again. You can also use any sort of dry heat like a heat gun, hair dryer or soldering iron if you want to heat specific sections of your creation.

Because it's such a new substance, it's true potential hasn't even been realised yet. That's where you, the super clever GeekCore pioneers come into play. You'll undoubtably be the ones who turn this amazing substance into something rediculously awesome and in the process get internet famous!

So get rolling, cutting, squashing, welding, moulding and drilling the possibilities are endless.


C9 melts to a putty-like consistency at only 50°C (122°F), easily achieved with hot water or air. You can form it into any shape you like. And because of its low heat conductivity, it doesn’t feel very hot, even at higher temperatures.

treeUnlimited Reusability

If you have built something and it didn’t work out or if you have an old project which is obsolete by now, simply put it in hot water and start again from where Compound 9 was shipped to you. Hopefully it will never become something called “waste”.

hammer High Impact Resistance

Compound 9 shows very high inner damping characteristics. Combined with its ductile nature it suits perfectly when shock absorbing capacity is required.

cross Self Healing

Minor inner micro-cracks can heal at room temperature and over days, as long as there is compressive internal stress involved.

bodybuilder Super Strong

Its tensile strength per weight competes with construction steel, whereas its stiffness is rather similar to modern plastics.

wrench Easy Repairability

If sudden mechanical overload has damaged the part you have built, simply heat up the area where the damage has occurred. Now, you can either form it back to its original state or reinforce the area with more C9 to make it stronger. Iterate this (damagereinforce) over and over again and you will archive the greatest design with least material and weight nature can offer.

rod Prototyping Reinvented

You don’t need to invest in machinery or tools. Things in your household will do the job. Drill holes with drinking straws, cut sheets with scissors. Of course, established industry machines will result in much higher precision and reproducibility. But for prototyping / proof of concept and functionality, it should do the job.

plane Ultra Lightweight

With a density of only 1.3 g/cm^3 it is much less dense than steel or aluminum.
