ShapeLock is an amazingly useful polycaprolactone plastic that starts to melt and become moldable at around 160ºF. When it cools to room temperature, it becomes rigid and tough with qualities similar to nylon. By heating it in water with a microwave or using a heat gun, you can easily hand form it into almost anything.

Check out these projects to get some ideas for what you can do with this impressive material:

I am the Evangelist for the Maker Shed. It seems that there is no limit to my making interests. I’m a tinkerer at heart and have a passion for solving problems and figuring out how things work. When not working for Make I can be found falling off my unicycle, running in adverse weather conditions, skiing down the nearest hill, restoring vintage motorcycles, or working on my car.
