Introduction: Bondic How-To - Customize Your LEGO Creations

LEGO is cool, there is no denying that. But Bondic can make it cooler!

Bondic® is the World's First pocket 3D liquid plastic welder that allows you to fix, fill, mold, and even build almost anything. It will only solidify when you cure it with the included UV LED light, so you control the drying time. Once the UV light hits, it only takes 4 seconds to harden with no pressure needed and it will not stick to your skin. Keep in mind that Bondic® is NOT A GLUE and should not be used like one. It literally is a welding tool that uses a unique formula to build new plastic around two objects instead of “gluing” two flat surfaces together. Think of Bondic® closer to that of a 3D printer, creating new material where it has been lost. Additionally, for Bondic® to stick onto surfaces, it needs to be rough to allow the Bondic® fluid to seep into the pores of said objects and literally “grab” onto them when cured. We always like to think of Bondic as like gripping something with your hands. If you are trying to grab onto a smooth surface it will be really difficult to do so. But if the surface is rough, you can get a much better grip.

Step 1: Make the Surface Rough

Before you start creating your own pieces on the LEGO set, make sure you roughen the surface you are applying Bondic on. For this, you can use a nail file or sand paper.

Bondic needs a rough surface area to be able to "grab" onto things when it cures. The rougher the surface, the stronger the hold.

Step 2: Apply Bondic

Bondic will always cure to itself, the bond is so cohesive, every layer you make will fuse into one solid piece. To begin making hooks add drop layer of Bondic (roughly 0.5mm) and cure it with the UV light for 4 seconds. One trick to use is to simply tap the end of the light against the drop you are curing, if the light does not stick then it is 100% hard plastic now.

Keep building layer by layer (like a 3D printer) until you have created the desired shape.

You can create hooks, shapes and designs on any part!

Step 3: Cloning Shapes With Silly Putty

One of the coolest features of Bondic is being able to clone shapes using silly putty.

Start by pressing in any shape or piece into the putty and pull it out leaving a perfect mold.

Next, add in a layer of Bondic to the mold (roughly 0.5mm in size) and begin curing. Keep adding layer after layer until you have completely filled up the shape in the silly putty.

Step 4: Finalizing Your Mold

Once your mold is completely filled up and 100% cured, you can now pull it out. If there are any
imperfections, just use your nail file and shape it to the exact size you want!
